Is open to the public.

한국공개특허공보 특2003-0038009(감귤박에서 연속공정에 의한 플라보노이드와 펙틴의 추출 및 정제방법)에는, 감귤박에 메탄올을 넣고 가열하여 플라보노이드를 추출하고, 그 잔사를 분말화하고 여기에 염산과 물을 투입하여 추출하고, 동결건조시켜 펙틴을 추출하는 것으로 구성된 연속공정에 의한 플라보노이드와 펙틴의 추출 및 정제방법에 관한 것이 공개되어 있다.In Korean Patent Laid-Open Publication No. 2003-0038009 (a method of extracting and purifying flavonoids and pectins by a continuous process from citrus fruits), methanol is added to citrus fruits and heated to extract flavonoids, and the residue is powdered and hydrochloric acid and Disclosed is a method for extracting and purifying flavonoids and pectins by a continuous process comprising extraction by adding water, lyophilization and extracting pectin.

그러나, 종래의 방법으로 감귤류에서 플라보노이드를 추출하면 추출된 플라보노이드 양이 극히 적고, 생리활성도 다소 떨어지며, 네오헤스페리딘을 다량 추출하기도 어려웠다.However, when the flavonoids are extracted from citrus fruits by the conventional method, the amount of the extracted flavonoids is extremely small, the physiological activity is slightly reduced, and it is difficult to extract a large amount of neohesperidin.

한국식품과학회지 "제주재래종 감귤류 미숙과의 neohesperidin, naringin 및 hesperidin 함량"(류미라 외, Vol. 34, No.1, pp. 132-135(2002) 에는, 제주 재래종 감귤류 9 종 즉, 당유자, 지각, 편귤, 감자, 동정귤, 병귤, 빈귤, 사두감, 진귤 에서 각 숙기별로 시료를 분석한 결과, 당유자와 지각은 네오헤스페리딘과 나린진의 함량이 높고, 빈귤과 동정귤은 헤스페리딘의 함량이 높다는 내용이 공개되어 있다.The Korean Society of Food Science and Technology "Neohesperidin, naringin and hesperidin Contents of Jeju Native Citrus Fruits Immature" (Ryu Mira et al., Vol. 34, No.1, pp. 132-135 (2002)) show that 9 kinds of Jeju citrus fruits, As a result of analyzing the samples by each ripening season, crust, cinnamon, potato, virgin tangerine, bottle tangerine, bilberry, tangerine, and tangerine, sugar and crust have high content of neohesperidin and naringin, and This high content is open to the public.

그러나, 상기와 같은 내용은 각 감귤류의 플라보노이드의 함량을 단순히 분석한 것으로서, 감귤류의 플라보노이드 함량이 다소 적으며, 또한 실질적으로 다양하게 활용하기 위해서 감귤류에서 분획물을 다량 제조하기는 어려웠다.However, the above contents are simply analyzed the content of each citrus flavonoid, the citrus flavonoid content is somewhat less, and it was difficult to prepare a large amount of fractions in citrus fruits to utilize a variety.

한편, 당유자(Citrus grandis)는 제주도에서 자생되는 약용과일로써, 유자보다 열매가 약 10 배 정도 크고, 나린진 등의 플라보노이드가 풍부해 기침과 감기에 좋다고 알려진 과실이다.On the other hand, Citrus grandis is a medicinal fruit native to Jeju Island, which is about 10 times larger in fruit than citron and rich in flavonoids such as naringin, which is known to be good for coughing and colds.

종래에 감귤류 유래 플라보노이드 중 당유자와 지각에서 네오헤스페리딘의 함량이 높다는 사실이 알려져 있으나, 실제로 해당 과실에서 분획물을 다량 분획하기가 어려웠으며, 종래의 방법과 같이 일반적인 추출물로 제조하면 생리활성도 높지 않는 문제점이 있었다.It is known that the content of neohesperidin is high in the sugar crust and the crust of citrus-derived flavonoids, but it is difficult to fractionate a large amount of fractions from the fruit, and when prepared as a general extract as in the conventional method, the biological activity is not high. There was this.

따라서, 당유자에서 플라보노이드를 다량 분획하여 종래의 감귤류보다 경제성이 높고, 생리활성 또한 높아 보다 폭넓게 활용할 수 있는 연구가 더욱 필요한 실정이다.Therefore, a large amount of flavonoids from sugar-sugars is more economical than conventional citrus fruits, and the biophysical activity is also high.

본 발명은 상기의 문제를 해결하기 위해, 당유자로부터 네오헤스페리딘을 포함하는 플라보노이드 분획조성물의 제조방법을 제공하는데 그 목적이 있다.In order to solve the above problems, an object of the present invention is to provide a method for producing a flavonoid fraction composition comprising neohesperidine from sugar.

당유자(Citrus grandis)는 제주도에서 자생되는 약용과일로써, 유자보다 열매가 약 10 배 정도 크고, 나린진 등의 플라보노이드가 풍부해 기침과 감기에 좋다고 알려진 과실이다.Citrus grandis is a medicinal fruit that grows on Jeju Island. Fruit is about 10 times larger than citron and rich in flavonoids such as naringin, which is known to be good for coughing and colds.

종래에 감귤류 유래 플라보노이드 중 당유자와 지각에서 네오헤스페리딘의 함량이 높다는 사실이 알려져 있으나, 실제로 해당 과실에서 분획물을 다량 분획하기가 어려웠으며, 종래의 방법과 같이 일반적인 추출물로 제조하면 생리활성도 높지 않는 문제점이 있었다.It is known that the content of neohesperidin is high in the sugar crust and the crust of citrus-derived flavonoids, but it is difficult to fractionate a large amount of fractions from the fruit, and when prepared as a general extract as in the conventional method, the biological activity is not high. There was this.

본 발명의 발명자들은 상기의 문제를 해결하기 위해 당유자를 이용하여 네오헤스페리딘이 다량 함유된 분획물을 다량 분획하고, 생리활성 또한 뛰어난 플라보노이드 분획조성물을 제조하기 위해 많은 시행착오를 겪으며 본 발명을 완성하였다.In order to solve the above problems, the inventors of the present invention have undergone many trials and errors to prepare a flavonoid fraction composition having a large fraction of neohesperidine-containing fractions and a physiologically active flavonoid fraction composition. .

본 발명의 당유자 유래 네오헤스페리딘이 포함된 플라보노이드 분획조성물은 당유자 미숙과를 분쇄하고, 이 분쇄물에 80 % 메탄올 수용액을 상기 분쇄물 1 ㎏ 당 1.5 ℓ를 가한 다음, 1 시간 동안 80 ~ 90 ℃로 중탕하여 1차 추출하고, 이 1차 추출액을 감압여과하여 여과액을 얻은 후, 이 여과액에 상기 과정을 반복하여 2차 추출액을 제조하고, 이 2차 추출액을 감압농축하되 감압농축시 암갈색 시럽 상태로 변할때 30 % 에탄올을 가하여 노란색 침전이 생기게 하고, 이를 원심분리하여 침전물을 제거한 후 완전히 농축하여 농축물을 제조한 다음, 이 농축물에 농축물의 중량대비 25 배의 증류수를 넣고 녹인 후 여과한 여과액을 초미세여과 키트를 이용하여 여과하고, 이 여과액을 MPLC 컬럼에 XAD-16 레진을 충진하여 30 % 에탄올 용액으로 용출시켜 플라보노이드 분획조성물을 얻는다.Flavonoid fraction composition containing the sugar-derived neohesperidine-derived sugar of the present invention is pulverized, the sugar-dried immature fruit fruit, 80 L aqueous solution of 1.5% per kg of the pulverized powder is added, 80-90 for 1 hour After primary extraction with a water bath at 50 ° C., the primary extract was filtered under reduced pressure to obtain a filtrate, and the filtrate was repeated to prepare a secondary extract, and the secondary extract was concentrated under reduced pressure. 30% ethanol is added to give a yellow precipitate when it turns into dark brown syrup. The precipitate is removed by centrifugation, and the concentrate is completely concentrated to make a concentrate. Then, 25 times of distilled water is added to the concentrate and dissolved. The filtrate was filtered using an ultrafiltration kit, and the filtrate was filled with XAD-16 resin in an MPLC column and eluted with a 30% ethanol solution. To obtain a composition.

상기 방법에 의해 제조된 본 발명의 당유자 유래 플라보노이드 분획물은 당유자 전체 중량대비 9 ~ 16 %를 얻을 수 있으며, 그 전체분획물 중 네오헤스페리딘은 60 ~ 70 %, 나린진은 20 ~ 35 %를 차지했다.The sugar-derived flavonoid fraction of the present invention prepared by the above method was able to obtain 9-16% of the total weight of sugar-oil, and neohesperidine was 60-70% and naringin 20-35% of the total fraction. .

상기와 같이 분획했을때 가장 분획조성물의 양이 많았으며, 네오헤스페리딘의 양을 다량 분획할 수 있었다.When fractionated as described above, the amount of the most fraction composition was large, and the amount of neohesperidin could be largely fractionated.

본 발명의 플라보노이드 분획조성물 중 대부분을 차지하는 네오헤스페리딘 (Neohesperidin)은 감귤류 중 당유자, 지각, 편귤에 함유되어 있는 플라보노이드 중 하나이다.Neohesperidin, which occupies most of the flavonoid fraction composition of the present invention, is one of the flavonoids contained in sugar citron, crust, and citrus fruits of citrus fruits.

네오헤스페리딘을 수소 환원반응시키거나, 감귤류의 나린진으로부터 화학반응을 통해 네오헤스페리딘을 만들고 다시 수소 환원반응을 시켜 네오헤스피리딘 디히드로칼콘을 제조할 수 있다.Neohesperidine may be reduced by hydrogen reduction, or neohesperidine may be prepared by chemical reaction from citrus naringin, followed by hydrogen reduction to produce neohespyridine dihydrochalcone.

It is widely used because it can be widely used for sauces, spices, toothpaste, and mouthwashes.

이러한 네오헤스페리딘 디하이드로칼콘을 네오헤스페리딘으로 제조하기 때문에 네오헤스페리딘을 효율적으로 다량 분획하는 것은 산업상 이용가치가 매우 높은 것이라 할 수 있다.Since neohesperidine dihydrochalcone is prepared from neohesperidine, efficient fractionation of neohesperidine can be said to be of high industrial value.

또한, 네오헤스페리딘 자체도 생리활성이 뛰어날 것으로 추정되어 본 발명의 생리활성 실험을 수행하여, 그 생리활성을 입증하였다.In addition, neohesperidine itself was estimated to be excellent in physiological activity, and the physiological activity experiment of the present invention was performed to prove its physiological activity.

나린진(Naringin)은 감귤류에 다량 함유되어 있다고 널리 알려져 있는 물질로서 항산화작용, 항동맥경화작용, 항암작용을 하는 플라보노이드 중 하나이다.Naringin is one of the citrus fruits that is widely known as an antioxidant, anti-arteriosclerosis, and anti-cancer flavonoids.

나린진 또한 네오헤스페리딘 디하이드로칼콘으로 화학적 변환이 가능하다.Naringin can also be chemically converted to neohesperidine dihydrochalcone.

본 발명은 상기와 같은 특징을 갖고 있는 네오헤스페리딘과 나린진이 다량 함유되어 있는 플라보노이드 분획조성물을 당유자로부터 제조하여 쥬스, 음료, 주류, 제과, 소스류, 향신료, 치약, 구강청정제, 화장품 등에 다양하게 활용할 수 있다.The present invention prepares flavonoid fraction composition containing a large amount of neohesperidin and naringin having the above characteristics from sugar-dried milk, juices, beverages, alcoholic beverages, confectionery, sauces, spices, toothpaste, mouthwashes, cosmetics, etc. Can be.

크산틴 산화효소(xanthine oxidase)는 산화적 환경에서 크산틴 탈수소효소로부터 생성된다.Xanthine oxidase is produced from xanthine dehydrogenase in an oxidative environment.

크산틴 산화효소는 하이포크산틴을 산화시켜 최종적으로 요산과 산소를 형성하며, 산소유리기와 수소과산화기가 이 산소로부터 발생되게 된다.Xanthine oxidase oxidizes hypoxanthine and finally forms uric acid and oxygen, and oxygen free radicals and hydrogen peroxide groups are generated from this oxygen.

요산의 축적은 고요산형증과 통풍을 유발하는 것으로 알려져 있고, 크산틴 산화효소에 의해 생성된 산소유리기는 세포의 손상을 초래한다.Accumulation of uric acid is known to cause hyperuricosis and gout, and oxygen free radicals produced by xanthine oxidase cause cell damage.
