본원 발명은 구체적으로, The present invention specifically,

스피루리나를 황산 또는 메타올 용액에서 교반하는 단계(S 10);Stirring Spirulina in sulfuric acid or methanol solution (S 10);

상기 교반 스피루리나에 다이클로로메탄 및 물을 첨가 후, 유기층 용액을 수득하는 단계(S 20); After adding dichloromethane and water to the stirred Spirulina, obtaining an organic layer solution (S 20);

를 포함하는 클로린 e6염을 제조하는 방법이다. It is a method of producing a chlorine e6 salt containing.

칼럼크로마토그래피[column chromatography]는 유리관과 같은 원기둥 모양의 관에 산화알루미늄이나 이온교환수지 등을 충전한 칼럼을 사용한 크로마토그래피를 말한다. 칼럼의 충전제로서 산화알루미늄·활성탄·산화마그네슘 등을 사용한 것을 흡착크로마토그래피, 녹말·셀룰로스 등을 사용한 것을 분배크로마토그래피, 이온교환수지를 사용한 것을 이온교환크로마토그래피라고 한다.Column chromatography refers to chromatography using a column filled with aluminum oxide or an ion exchange resin in a cylindrical tube such as a glass tube. Adsorption chromatography using aluminum oxide, activated carbon, magnesium oxide, etc. as a filler for the column, distribution chromatography using starch, cellulose, etc., and ion exchange chromatography using an ion exchange resin.

본원 발명에서 상기 클로린 e6염을 제조하는 과정중에 사용된 크로마토그래피는 시료들이 섞여있는 혼합물을 이동상과 함께 정지상에 흘려보내면 시료의 특징에 따라 통과하는 속도가 다르다는 점을 이용해 시료를 분리해내기 때문에 별도의 정제과정을 거치는 종래에 비하여 현저하게 간단한 방법이므로, 이로 인해서 높은 생산성을 확보할 수 있게 된다. The chromatography used in the process of preparing the chlorine e6 salt in the present invention separates the sample by using the fact that the passing rate is different depending on the characteristics of the sample when the mixture in which the samples are mixed is passed along with the mobile phase. Since it is a remarkably simple method compared to the prior art that undergoes the purification process of, it is possible to secure high productivity.

<실시예><Example>

스피루리나 300g을 5%황산/메탄올 4L 용액에 12시간동안 교반한다. 다이클로로메탄과 물을 첨가 후, 분리된 유기층 용액 수득하고, 2% 아세톤/다이클로로메탄 용액으로 칼럼크로마토그래피로 정제함으로써 메틸페오포비드-a(Mpa)를 획득한다. 300 g of Spirulina was stirred in a 4 L solution of 5% sulfuric acid/methanol for 12 hours. After the addition of dichloromethane and water, a separated organic layer solution was obtained and purified by column chromatography with a 2% acetone/dichloromethane solution to obtain methyl peoh forbidden -a (Mpa).

상기 획득된 메틸페오포비드 -a(MPa)를 아세톤에 용해 후 5N의 수산화나트륨 (약 5당량)을 첨가한 후, 80℃에서 6시간 교반 후 여과함으로서 클로린 e6염을 제조한다. After dissolving the obtained methyl peoh forbidden -a (MPa) in acetone, 5N sodium hydroxide (about 5 equivalents) was added, stirred at 80° C. for 6 hours, and filtered to prepare a chlorine e6 salt.

상기와 같은 방법은 기존의 페오피틴을 거쳐서 클로린 e6염을 획득하는 과정에비하여 복잡한 정제과정을 거치지 않기 때문에 더욱 간단하게 클로린 e6염을 획득할 수 있는 이점이 있으며, 상기와 같은 방법에 의하여 획득된 클로린 e6염의 특성을 기존 다른 방법에 의해서 획득된 클로린 e6와 대비하여 볼 때, 더 나은 순도와 수득률을 가지는 것으로 확인된다. The above method has the advantage of more simply obtaining chlorine e6 salt because it does not undergo a complicated purification process compared to the process of obtaining chlorine e6 salt through conventional pheophytin, and is obtained by the above method. When the properties of the chlorine e6 salt are compared with the chlorine e6 obtained by other conventional methods, it is confirmed to have better purity and yield.

칼럼크로마토그래피는 시료를 액체용매로 일정한 압력으로 밀어 분리관인 칼럼관; Column)을 통과시켜 화합물을 분리하고 분석하는 방법으로서, 분리관의 충진제(고정상)과 시료(이동상)의 친화도에 의해 작용되는 압력으로 인한 흐름에 대한 저항이 발생하게 되므로, 고정상과 이동상의 친화도가 높으면 늦게 검출된다. 그래서 '고압 액체크로마토그래피(high pressure liquid chromatography)'라고 한다. Column chromatography is a column tube that is a separation tube by pushing a sample with a liquid solvent at a constant pressure; Column) to separate and analyze compounds.As resistance to flow occurs due to pressure applied by the affinity of the filler (fixed phase) and the sample (mobile phase) in the separation tube, the affinity of the stationary phase and the mobile phase If the degree is high, it is detected late. Therefore, it is called'high pressure liquid chromatography'.

그러므로, HPLC를 동일한 조건에서 측정하여 동일 시간의 peak가 측정되면 그 시간대의 물질은 같은 물질로 볼 수 있으며, 측정된 면적비율을 비교하여 순도 및 농도를 분석 할 수 있게 된다. Therefore, when HPLC is measured under the same conditions and the peak at the same time is measured, the material at that time can be regarded as the same material, and purity and concentration can be analyzed by comparing the measured area ratio.

그런데 도 3에서 보는 바와 같이, 기존의 방법에 의한 클로린 e6염은 측정시간이 3.637분이 대부분을 차지하기는 하지만, 그 외에 peak #1, #3~#7에서 다량의 불순물들이 검출되었다고 볼 수 있다. However, as shown in Figure 3, although the measurement time of chlorine e6 salt by the conventional method occupies most of 3.637 minutes, it can be seen that a large amount of impurities were detected in peaks #1 and #3 to #7. .

반면, 도 4에서 보는 바와 같이 본원발명의 방법에 의해 합성한 클로린 e6염은 peak #6에서 일분의 불순물과 기타 불순물이 검출되기는 하였지만, 그 양이 현저하게 적은 것을 알 수 있다. On the other hand, as shown in FIG. 4, although one minute of impurities and other impurities were detected at peak #6 in the chlorine e6 salt synthesized by the method of the present invention, it can be seen that the amount is remarkably small.

이처럼 본원 발명에 의한 칼럼크로마토그래피 측정결과 본원 발명에 의한 합성된 물질의 성분은 기준 물질의 주 peak가 3.637분에서 측정됨에 따라서, 합성한 물질의 HPLC에서도 3.637분에서 측정되어 같은 물질임을 확인할 수 있으며, 합성한 물질의 HPLC에서 측정된 전체 면적을 각 peak의 면적의 비율을 계산하여 순도가 약 97%이상의 순도를 가지는 것으로 측정되었다. As a result of column chromatography measurement according to the present invention, as the main peak of the reference substance is measured at 3.637 minutes, the components of the synthesized substance according to the present invention are measured at 3.637 minutes in HPLC of the synthesized substance, confirming that they are the same substance. , By calculating the ratio of the area of each peak to the total area measured by HPLC of the synthesized material, the purity was determined to have a purity of about 97% or more.

한편, 도 5는 종래방법에 의한 클로린 e6염과 본원 발명에 의한 클로린 e6염의 UV-Vis 비교를 그래프로 표시한 것이다.Meanwhile, FIG. 5 is a graph showing a comparison of UV-Vis between the chlorine e6 salt according to the conventional method and the chlorine e6 salt according to the present invention.

동일한 화합물은 UV-Vis에서 동일한 경향이 나타나게 되는데, 종래방법에 의한 클로린 e6염을 다양한 농도로 흡광도의 세기를 측정한 후, 본원 발명에 의한 클로린 e6염을 다양한 농도로 흡광도의 세기를 측정하였다. 이에 나타나는 흡광도 세기를 상호 비교하여 농도를 분석할 수 있다. 종래방법에 의한 클로린 e6염과 본원 발명에 의한 클로린 e6염의 UV-Vis 측정결과 동일한 경향의 peak가 측정되었다. The same compound shows the same tendency in UV-Vis. After measuring the absorbance intensity of the chlorine e6 salt according to the conventional method at various concentrations, the absorbance intensity of the chlorine e6 salt according to the present invention was measured at various concentrations. The concentration can be analyzed by comparing the absorbance intensity that appears. As a result of UV-Vis measurement of the chlorine e6 salt according to the conventional method and the chlorine e6 salt according to the present invention, peaks of the same trend were measured.
