Description

本発明は、主に、ノリ由来水溶性成分を含有する制癌剤、及び、ノリ由来水溶性成分を含有する食品組成物に関する。   The present invention mainly relates to an anticancer agent containing a laver-derived water-soluble component and a food composition containing a laver-derived water-soluble component.

ノリは、板ノリ、佃煮、粉末等に加工され、主に東南アジアで広く摂取されている食品である。ノリは、ビタミン、ミネラル、食物繊維等の栄養価に富んでおり、人々の食生活の健全化に大きく寄与している。   Nori is a food that has been processed into plate paste, boiled rice, powder, etc., and is widely consumed mainly in Southeast Asia. Nori is rich in nutritional values such as vitamins, minerals, and dietary fiber, and contributes greatly to the health of people's diet.

しかし、近年、ノリ生育環境の悪化により、ノリの色落ちや品質低下がもたらされており、商品価値の低い「色落ちノリ」や「下等ノリ」が大量に廃棄されている。   However, in recent years, the deterioration of the laver growing environment has led to the color fading and quality degradation of the laver, and a large amount of “colored laver” and “lower laver” with low commercial value are discarded.

このような廃棄ノリに新たな価値を見いだし、有効利用することが急務となっている。   There is an urgent need to find new value and effectively use such waste.

近年、褐藻類由来の多糖類が抗血管新生作用を通じて制癌効果を発現することが報告された(非特許文献1)。しかしながら、ノリ由来の水溶性成分の制癌効果については何ら示唆されていない。   In recent years, it has been reported that polysaccharides derived from brown algae express an anticancer effect through an anti-angiogenic action (Non-patent Document 1). However, there is no suggestion about the anticancer effect of the water-soluble component derived from laver.

また、アマノリ属藻類由来のグリセロ糖脂質がテロメラーゼ阻害を通じて制癌作用を発現する可能性が示された(非特許文献2、及び、非特許文献3)。しかしながら、グリセロ糖脂質はメタノール/クロロホルム混液等の毒性の強い有機溶媒を用いて抽出しなければならないため、グリセロ糖脂質を有効成分とする制癌剤の製造には、このような有機溶媒の調製、有機溶媒からのグリセロ糖脂質の精度の高い精製、有機溶媒の後処理等の工程が必要であり、省力化、省エネルギー化、環境保護等の観点から望ましくない。   Moreover, the possibility that the glyceroglycolipid derived from the genus Amanori algae develops an anticancer effect through telomerase inhibition was shown (Non-patent Documents 2 and 3). However, since glyceroglycolipids must be extracted using a highly toxic organic solvent such as methanol / chloroform mixture, the preparation of such organic solvents, organic Steps such as highly accurate purification of glyceroglycolipid from the solvent and post-treatment of the organic solvent are necessary, which is not desirable from the viewpoint of labor saving, energy saving, environmental protection and the like.

近年、ノリに含まれる高分子多糖類であるポルフィランに抗腫瘍活性を介した制癌作用があることが見出された(非特許文献4)。ポルフィランは約100,000又はそれ以上の分子量を有する分子であるが、体内への吸収効率の点では、一般的に、より低分子であることが望ましい。
今まで、水等の水性溶媒により簡便に抽出できる低分子ノリ由来成分の制癌作用は報告されていない。

In recent years, it has been found that porphyran, which is a polymeric polysaccharide contained in paste, has an anticancer activity via antitumor activity (Non-Patent Document 4). Porphyran is a molecule having a molecular weight of about 100,000 or more, but it is generally desirable to be a lower molecule in terms of absorption efficiency into the body.
Until now, the anticancer action of low molecular glue derived components that can be easily extracted with an aqueous solvent such as water has not been reported.

本発明者らは、ノリの新規用途を見出すべく鋭意研究を行った結果、ノリから抽出した水溶性成分のうち、ポアサイズ2000オングストロームのフィルターを通過する成分が癌細胞の増殖を抑制することを見出し、本発明を完成するに至った。   As a result of diligent research to find a new use of paste, the present inventors have found that, among water-soluble components extracted from paste, a component that passes through a filter having a pore size of 2000 angstroms suppresses the growth of cancer cells. The present invention has been completed.

以下、本発明をより詳細に説明する。
〔I〕ノリ由来水溶性成分
本発明の制癌剤及び食品組成物に含まれるノリ由来水溶性成分は、ポアサイズ2000オングストロームのフィルターを通過する。例えば、本発明の制癌剤及び食品組成物に含まれるノリ由来水溶性成分は、水に溶解した場合に、pH3〜10程度、好ましくはpH4〜8程度、さらに好ましくはpH5〜7程度、温度0〜90℃程度、好ましくは3〜65℃程度の限外濾過条件下において、2000オングストロームのポアサイズを有するセラミック膜式濃縮装置(例えば、株式会社ノリタケカンパニーリミテド製セラミックフィルター)を通過することができる分子である。このようにポアサイズ2000オングストロームのフィルターを通過できる分子は、約10,000以下の分子量を有する低分子であると考えられる。それゆえ、本発明の制癌剤の有効成分であるノリ由来水溶性成分は、約100,000程度、あるいはそれ以上の分子量を有するポルフィランのような高分子とは異なる低分子であると考えられる。
Hereinafter, the present invention will be described in more detail.
[I] Nori-derived water-soluble component The nori-derived water-soluble component contained in the anticancer agent and food composition of the present invention passes through a filter having a pore size of 2000 angstroms. For example, the paste-derived water-soluble component contained in the anticancer agent and food composition of the present invention, when dissolved in water, has a pH of about 3 to 10, preferably about pH 4 to 8, more preferably about pH 5 to 7, and a temperature of 0 to A molecule that can pass through a ceramic membrane concentrator having a pore size of 2000 angstroms (for example, a ceramic filter manufactured by Noritake Co., Ltd.) under ultrafiltration conditions of about 90 ° C., preferably about 3 to 65 ° C. is there. Thus, molecules that can pass through a filter having a pore size of 2000 angstrom are considered to be small molecules having a molecular weight of about 10,000 or less. Therefore, the Nori-derived water-soluble component, which is an active ingredient of the anticancer agent of the present invention, is considered to be a low molecule different from a polymer such as porphyran having a molecular weight of about 100,000 or more.

本発明におけるノリ由来水溶性成分は、水、水系緩衝液(リン酸緩衝液、クエン酸緩衝液、酢酸緩衝液等)、生理的食塩水、ブドウ糖溶液、リンゲル液等の水をベースとする溶液には実質的に可溶性であるが、エタノール、アセトン、1−ブタノール、2−プロパノール、酢酸エチル、クロロホルム、ヘキサンには実質的に不溶性である。それゆえ、本発明におけるノリ由来水溶性成分の主構造は、典型的な脂質又は糖脂質とは異なる構造であると考えられる。   The water-soluble component derived from laver in the present invention is a water-based solution such as water, aqueous buffer solution (phosphate buffer solution, citrate buffer solution, acetate buffer solution, etc.), physiological saline, glucose solution, Ringer solution, etc. Is substantially soluble, but is substantially insoluble in ethanol, acetone, 1-butanol, 2-propanol, ethyl acetate, chloroform, and hexane. Therefore, the main structure of the water-soluble component derived from laver in the present invention is considered to be a structure different from typical lipids or glycolipids.

本発明におけるノリ由来水溶性成分は、常法により製造することができ、例えば、ノリを水中で常温〜120℃にて0.5〜20時間加熱し、水の添加による冷却後、固液分離を行い、熱水可溶性抽出液を得たのち、2000オングストロームのポアサイズを有するフィルターを用いて限外濾過を行なうことにより製造することができる。限外濾過フィルターとしては、2000オングストロームのポアサイズを有する平膜式限外濾過装置、中空糸膜式限外濾過装置、セラミック膜式濃縮装置(例えば、株式会社ノリタケカンパニーリミテド製セラミックフィルター)を好適に用いることができる。限外濾過のフィルターとして中空糸膜やセラミックフィルター等の限外濾過膜を使用した場合には、濃縮と高分子成分の除去を同時に達成することができる。限外濾過に供するときのノリ由来水溶性成分を含む溶液のpHは、ノリ由来水溶性成分の構造変化をもたらすような強酸又は強アルカリでない限り特に限定されず、例えば、pH3〜10程度、好ましくはpH4〜8程度、さらに好ましくはpH5〜7程度であり、温度は、特に限定されず、作業効率を高めるには、例えば、0〜90℃程度、好ましくは3〜65℃程度である。ノリ由来水溶性成分を水で抽出した溶液を、pH調整しないまま限外濾過に供する場合、溶液のpHは通常pH5〜7程度になる。限外濾過中多少のpH変化が生じることがあるが、上記範囲内であれば、限外濾過やノリ由来水溶性成分の抗癌作用にはほとんど影響しないと考えられる。また、温度の変化が、限外濾過やノリ由来水溶性成分の制癌作用に及ぼす影響もほとんどないと考えられる。必要に応じて、殺菌、濃縮、乾燥、造粒等の操作を行ってもよい。このとき濃縮は、例えば、常圧加熱濃縮、減圧濃縮等の常法により行うことができる。また乾燥は、噴霧乾燥、真空乾燥、エバポレーターによる乾燥、凍結乾燥等の常法により行うことができる。ノリ由来水溶性成分を得る方法は、これらの方法に限定されない。   The glue-derived water-soluble component in the present invention can be produced by a conventional method. For example, the glue is heated in water at room temperature to 120 ° C. for 0.5 to 20 hours, cooled by addition of water, and then solid-liquid separated. To obtain a hot water-soluble extract, followed by ultrafiltration using a filter having a pore size of 2000 angstroms. As the ultrafiltration filter, a flat membrane type ultrafiltration device having a pore size of 2000 angstroms, a hollow fiber membrane type ultrafiltration device, and a ceramic membrane type concentrating device (for example, a ceramic filter manufactured by Noritake Co., Ltd.) are preferably used. Can be used. When an ultrafiltration membrane such as a hollow fiber membrane or a ceramic filter is used as the ultrafiltration filter, concentration and removal of the polymer component can be achieved simultaneously. The pH of the solution containing the seaweed-derived water-soluble component when subjected to ultrafiltration is not particularly limited as long as it is not a strong acid or strong alkali that causes a structural change of the seaweed-derived water-soluble component, for example, about pH 3 to 10, preferably Is about pH 4-8, more preferably about pH 5-7, and the temperature is not particularly limited, and is about 0-90 ° C., preferably about 3-65 ° C., for example, in order to increase working efficiency. When the solution obtained by extracting the water-soluble component derived from laver with water is subjected to ultrafiltration without adjusting the pH, the pH of the solution is usually about 5 to 7. Although some pH change may occur during ultrafiltration, it is considered that the anti-cancer effect of ultrafiltration and the water-soluble component derived from seaweed is hardly affected as long as it is within the above range. In addition, it is considered that the change in temperature has little influence on the anti-cancer effect of ultrafiltration and paste-derived water-soluble components. You may perform operations, such as sterilization, concentration, drying, and granulation, as needed. At this time, the concentration can be performed by a conventional method such as normal pressure heating concentration or reduced pressure concentration. Drying can be carried out by conventional methods such as spray drying, vacuum drying, drying with an evaporator, freeze drying and the like. The method for obtaining the paste-derived water-soluble component is not limited to these methods.

ノリの由来は、特に限定されないが、好ましくはアマノリ属藻類及びウシケノリ属藻類からなる群より選択される少なくとも1種であり、特にアマノリ属藻類が好ましい。アマノリ属藻類の中でも、特に、スサビノリ、アサクサノリ及び檀紫菜からなる群より選択される少なくとも1種が好ましく、特にスサビノリが好ましい。スサビノリから得られた本発明のノリ由来水溶性成分は、癌細胞に対して強い増殖抑制効果を発揮することができる。
〔II〕ノリ由来水溶性成分中のメタノール可溶性成分及びメタノール不溶性成分
本発明者らは、さらに、ポアサイズ2000オングストロームのフィルターを通過するノリ由来水溶性成分がメタノール可溶性成分とメタノール不溶性成分とを含有し、この各々が癌細胞に対して増殖抑制効果を発揮することを見出した。
The origin of the laver is not particularly limited, but is preferably at least one selected from the group consisting of the genus Alori and the genus Algeria, and is particularly preferably Algae. Among the algae species, at least one selected from the group consisting of Susavinori, Asakusanori and Danshakusai is particularly preferred, and Susabiori is particularly preferred. The seaweed-derived water-soluble component of the present invention obtained from Susabiori can exert a strong growth inhibitory effect on cancer cells.
[II] Methanol-soluble component and methanol-insoluble component in laver-derived water-soluble component The present inventors further include that the laver-derived water-soluble component that passes through a filter having a pore size of 2000 angstroms contains a methanol-soluble component and a methanol-insoluble component. The present inventors have found that each of these exhibits a growth inhibitory effect on cancer cells.

メタノール可溶性成分及びメタノール不溶性成分は、常法、例えば次のような方法により得ることができる:ノリ由来水溶性成分をメタノールに懸濁し、4〜100℃にて0〜20時間抽出し、次いで抽出液を遠心分離し、遠心上清及び沈殿物を別々に回収する。遠心上清および沈殿物は、適宜、濃縮、乾燥、凍結乾燥、精製、造粒、殺菌等を行ってもよい。このように得られた遠心上清をメタノール可溶性成分、沈殿物をメタノール不溶性成分として使用することができる。メタノール可溶性成分及びメタノール不溶性成分を得る方法は、これらの方法に限定されない。   The methanol-soluble component and the methanol-insoluble component can be obtained by a conventional method, for example, the following method: The water-soluble component derived from laver is suspended in methanol, extracted at 4 to 100 ° C. for 0 to 20 hours, and then extracted. Centrifuge the solution and collect the supernatant and precipitate separately. The centrifugal supernatant and the precipitate may be appropriately concentrated, dried, lyophilized, purified, granulated, sterilized and the like. The centrifugal supernatant thus obtained can be used as a methanol-soluble component, and the precipitate as a methanol-insoluble component. The method for obtaining the methanol-soluble component and the methanol-insoluble component is not limited to these methods.

メタノール可溶性成分及びメタノール不溶性成分は、オートクレーブ滅菌してもその制癌作用が低下しない。   Methanol-soluble components and methanol-insoluble components are not reduced in their anticancer effects even when autoclaved.

メタノール可溶性成分及びメタノール不溶性成分をpH7.4の生理リン酸緩衝液(PBS)に懸濁し、Ultraspec 3000 Spectrophotometer(Pharmacia Biotech, City, State)により紫外可視スペクトルを測定したところ、メタノール可溶性成分は336nm、メタノール不溶性成分は253nmに吸収極大を示した。
〔III〕制癌作用
本発明におけるポアサイズ2000オングストロームのフィルターを通過するノリ由来水溶性成分は、骨髄性白血病細胞(例えば、ヒト前骨髄性白血病細胞HL−60)、悪性黒色腫細胞(例えば、マウスメラノーマB16)等の癌細胞の増殖を抑制することができる。
A methanol-soluble component and a methanol-insoluble component were suspended in a physiological phosphate buffer (PBS) having a pH of 7.4, and an ultraviolet-visible spectrum was measured using an Ultraspec 3000 Spectrophotometer (Pharmacia Biotech, City, State). The methanol-soluble component was 336 nm. The methanol-insoluble component showed an absorption maximum at 253 nm.
[III] Anticancer activity The water-soluble component derived from Nori that passes through a filter having a pore size of 2000 angstroms in the present invention is myeloid leukemia cells (for example, human promyelocytic leukemia cells HL-60), malignant melanoma cells (for example, mice) The proliferation of cancer cells such as melanoma B16) can be suppressed.

制癌作用の程度は、ノリ由来水溶性成分存在下における癌細胞の増殖率が、ノリ由来水溶性成分非存在下における癌細胞の増殖率と比べて低い限りにおいて限定されない。例えば、ノリ由来水溶性成分113μg/mlの存在下では、ヒト前骨髄性白血病細胞HL−60の増殖率を、ノリ由来水溶性成分非存在下の場合の約50%以下にまで低減させることができる。   The degree of anticancer action is not limited as long as the growth rate of cancer cells in the presence of a water-soluble component derived from laver is lower than the growth rate of cancer cells in the absence of a water-soluble component derived from laver. For example, in the presence of 113 μg / ml of a water-soluble component derived from seaweed, the growth rate of human promyelocytic leukemia cells HL-60 can be reduced to about 50% or less of that in the absence of a water-soluble component derived from seaweed. it can.

さらに、前記ノリ由来水溶性成分に含まれるメタノール可溶性成分及びメタノール不溶性成分は、それぞれ単独で、骨髄性白血病細胞(例えば、ヒト前骨髄性白血病細胞HL−60)、悪性黒色腫細胞(例えば、マウスメラノーマB16)等の癌細胞の増殖を抑制する作用を有する。

これらの有機溶媒100mLに1000mgのノリ由来水溶性成分を懸濁し、37℃で1時間抽出した。この懸濁液を300xgで30秒間遠心分離した。遠心上清を減圧乾燥し、有機溶媒可溶性成分を得た。この有機溶媒可溶性成分全量を秤量後、有機溶媒と同量のPBS100mlに再溶解した。一方、沈殿物を減圧乾燥し、有機溶媒不溶性成分を得た。この有機溶媒不溶性成分全量を秤量後、有機溶媒と同量のPBS100mlに再溶解した。各PBS溶液を10000xgで5分間遠心分離し、上清をオートクレーブ滅菌し、それぞれ有機溶媒可溶性成分サンプル及び有機溶媒不溶性成分サンプルとし、後の癌細胞増殖抑制試験に用いた。   In 100 mL of these organic solvents, 1000 mg of a nori-derived water-soluble component was suspended and extracted at 37 ° C. for 1 hour. This suspension was centrifuged at 300 × g for 30 seconds. The centrifugal supernatant was dried under reduced pressure to obtain an organic solvent-soluble component. The total amount of the organic solvent-soluble component was weighed and redissolved in 100 ml of PBS in the same amount as the organic solvent. On the other hand, the precipitate was dried under reduced pressure to obtain an organic solvent insoluble component. The total amount of the organic solvent insoluble component was weighed and then redissolved in 100 ml of PBS in the same amount as the organic solvent. Each PBS solution was centrifuged at 10,000 × g for 5 minutes, and the supernatant was autoclaved to obtain an organic solvent-soluble component sample and an organic solvent-insoluble component sample, respectively, and used for the subsequent cancer cell growth inhibition test.

<癌細胞の培養>
癌細胞として、ヒト前骨髄性白血病由来HL−60細胞及びマウスメラノーマB16細胞を使用した。各癌細胞株は、5%FBS含有RPMI1640培地を用いて37℃で培養し、5〜7日の周期で継代して株細胞を維持させた。各培養液を5x10cells/mLの細胞密度になるよう1%FBS含有RPMI1640培地にまきこみ、24時間培養した。この癌細胞培養プレートを、後の癌細胞増殖抑制試験に用いた。
<Culture of cancer cells>
As cancer cells, human promyelocytic leukemia-derived HL-60 cells and mouse melanoma B16 cells were used. Each cancer cell line was cultured at 37 ° C. using RPMI1640 medium containing 5% FBS, and the cell lines were maintained by subculture in a cycle of 5 to 7 days. Each culture solution was soaked in RPMI 1640 medium containing 1% FBS so as to have a cell density of 5 × 10 4 cells / mL, and cultured for 24 hours. This cancer cell culture plate was used for a later cancer cell growth inhibition test.

<癌細胞増殖抑制試験>
1.癌細胞の増殖に及ぼす影響
前述のノリ由来水溶性成分(PBS溶液、10mg/ml)を各癌細胞培養プレートに培地の10分の1量添加し、37℃にて48時間培養後、細胞数を測定した。結果を表1に示す。
<Cancer cell growth inhibition test>
1. Effect on growth of cancer cells The above-mentioned glue-derived water-soluble component (PBS solution, 10 mg / ml) is added to each cancer cell culture plate in one-tenth of the medium, cultured at 37 ° C. for 48 hours, and the number of cells. Was measured. The results are shown in Table 1.

Figure 2007261963

この結果から、ノリ由来水溶性成分の顕著な増殖抑制効果が明らかとなった。   From this result, the remarkable growth inhibitory effect of the paste-derived water-soluble component was revealed.

更に、前述の有機溶媒可溶性成分(PBS溶解品)及び有機溶媒不溶性成分(PBS溶解品)をHL−60細胞培養プレートに培地の10分の1量添加し、48時間培養後、細胞数を測定した。結果及びノリ由来水溶性成分の各種有機溶媒への分配率を表2に示す。   Furthermore, the above-mentioned organic solvent soluble component (PBS dissolved product) and organic solvent insoluble component (PBS dissolved product) were added to an HL-60 cell culture plate at one-tenth of the medium, and after 48 hours of culture, the number of cells was measured. did. Table 2 shows the results and the distribution ratios of the water-soluble component derived from laver to various organic solvents.

Figure 2007261963
Figure 2007261963

この結果から、メタノールを除く試験した全ての有機溶媒に対してノリ由来水溶性成分は溶解性をほとんど示さず、また、僅かな可溶性画分も細胞増殖の抑制作用を認めなかった。しかしながら、メタノールに対しては、水溶性成分の総重量の約65.6%がメタノール可溶画分に、約34.4%がメタノール不溶性画分にそれぞれ分配され、両方の画分において細胞増殖の抑制活性が認められた。   From this result, it was found that the water-soluble component derived from Nori showed almost no solubility in all the organic solvents tested except methanol, and even a small amount of the soluble fraction showed no inhibitory effect on cell proliferation. However, for methanol, about 65.6% of the total weight of the water-soluble components is distributed in the methanol-soluble fraction and about 34.4% in the methanol-insoluble fraction, with cell growth in both fractions. Inhibitory activity was observed.

メタノール可溶性成分サンプル及びメタノール不溶性成分サンプルが、コントロールサンプル(PBSのみ)と比べてHL−60細胞に対して有意に強い増殖抑制作用を示した。   The methanol-soluble component sample and the methanol-insoluble component sample showed a significantly stronger growth inhibitory action on HL-60 cells than the control sample (PBS only).

そこで、メタノール可溶性成分サンプル及びメタノール不溶性成分サンプルについてUltraspec 3000 Spectrophotometer(Pharmacia Biotech, City, State)を用いて紫外可視スペクトルの測定を行った。メタノール可溶性成分は336nmに吸収極大を示し、メタノール不溶性成分は253nmに吸収極大を示した。   Therefore, the UV-visible spectrum of the methanol soluble component sample and the methanol insoluble component sample was measured using an Ultraspec 3000 Spectrophotometer (Pharmacia Biotech, City, State). The methanol-soluble component showed an absorption maximum at 336 nm, and the methanol-insoluble component showed an absorption maximum at 253 nm.

2.癌細胞の増殖に及ぼす濃度依存的影響
ノリ由来水溶性成分サンプル(10mg/ml)の2倍、2倍、2倍、2倍、2倍、2倍、2倍希釈液を調製した。各希釈液を各癌細胞培養プレートに培地の10分の1量添加し、48時間培養後、細胞数を測定した。結果を図1に示す。
2. 2 0 times from concentration-dependent effects laver on cancer cell proliferation soluble component samples (10mg / ml), 2 1-fold, 2 doubles, 2 triple, 2 four times, 2 5-fold, 2 6-fold dilution A liquid was prepared. Each dilution was added to each cancer cell culture plate in one-tenth of the medium, and after 48 hours of culture, the number of cells was measured. The results are shown in FIG.

この結果から、細胞増殖の抑制は2倍希釈液で既に有意に認められ、その作用は濃度依存的に上昇した。 From this result, suppression of cell proliferation was already significantly observed with the 26- fold dilution, and the effect increased in a concentration-dependent manner.

更に、メタノール可溶性成分サンプル(6.56mg/ml)及びメタノール不溶性成分サンプル(3.44mg/ml)の2倍、2倍、2倍、2倍希釈液を調製した。各濃度の希釈液を各癌細胞培養プレートに培地の10分の1量添加し、48時間培養後、細胞数を測定した。結果を図2に示す。 Furthermore, 2 0 times the methanol soluble component samples (6.56 mg / ml) and methanol insoluble component samples (3.44mg / ml), 2 1-fold, 2 twice, to prepare a 2 3-fold dilutions. One-tenth of the medium was added to each cancer cell culture plate at each concentration, and the number of cells was measured after 48 hours of culture. The results are shown in FIG.

この結果からメタノール可溶性画分と不溶性画分の両方に、濃度依存的な細胞増殖の抑制作用が認められることがわかる。なお、その抑制作用はメタノール不溶性画分において、より強く認められた。   From this result, it can be seen that concentration-dependent cell growth-inhibiting action is observed in both the methanol-soluble fraction and the insoluble fraction. The inhibitory action was more strongly observed in the methanol-insoluble fraction.

3.癌細胞の増殖に及ぼす経時的影響
ノリ由来水溶性成分サンプル(10mg/ml)を各癌細胞培養プレートに培地の10分の1量添加し、0、24、48、72、96、120時間培養後の細胞数を測定した。結果を図3に示す。
3. Time-dependent influence on cancer cell growth Add a 1/10 volume of water-soluble component sample (10 mg / ml) derived from Nori to each cancer cell culture plate, and culture for 0, 24, 48, 72, 96, 120 hours Later cell numbers were measured. The results are shown in FIG.

この結果から、ノリ由来水溶性成分は培養期間120時間においても顕著な増殖抑制効果を示すことがわかる。   From this result, it can be seen that the glue-derived water-soluble component shows a remarkable growth inhibitory effect even in the culture period of 120 hours.
