Panax ginseng C.A Meyer is frequently taken orally as a traditional herbal medicine in Asian countries. The major components of ginseng are ginsenoside, which are pharmaceutical activity. The six major ginsenosides, including Rb1, Rb2, Rc, Rd, Re and Rg1 account for 90% of total ginsenosides. Even though the minor ginsenosides, including Rg3, Rh2 and compound K has high pharmacetical activities, the price of minor ginsenosides is too high. Therefore we isolated the gypenoside V and made it converted to minor ginsenosides. In the plant Gynostemma pentaphyllum Makino, gypenosdie V was presented as dominant saponin (content about 2.4%), and was similar to protopanaxadol type ginsenosides such as ginsenoside Rb1. In this study, we confirmed that the coversion of gypenoside V to minor ginsenosides after using the various treatment such as heating, acid treatment, commercial edible enzyme, and lactobacillus. Consequently, we optimizied the transformation of gypenoside V to minor ginsenoside using Thin Layer Chromatography (TLC), High Performance Liquid Chromatography (HPLC), Time-of-flight Mass Spectrometry (LC/TOF/MS).

Fuiarium solani 와 Phytophthora cactorum 이 인삼 사포닌 성분에 어떠한 영향을 미치는가를 알기 위해서 각 첨가배지에서의 균사생육과 접종된 인삼분말의 사포닌 분석실험으로 다음과 같은 결과를 얻었다. Fuiarium solani는 수삼의 물추출물 농도에 따라 생육이 억제되었으며 조사포닌 20ppm 첨가까지 생육이 촉진되었으나 50ppm이상에서는 불규칙적인 생육 억제효과가 있었다. 그리고 nystatin은 농도에 다라 생육을 억제하였다. Phytophthora cactorum은 수삼의 물추출액, 조사포닌의 농동에 따라서 생육은 촉진되었으며 nystatin은 생육에 영향을 미치지 않았다. F. solani 및 P. cactorum 으로 접종된 인삼분말은 ginsenoside Ra, Ro peak가 나타나지 않았으며 F. solani에 의해 PD 계 ginsenoside가 3.0% 증가되고 PT계 ginsenosides는 34.9% 감소되었다. P. cactorum의 경우는 PD 계 ginsenoside가 21.1% 증가, PT계 ginsenosides는 23.5% 감소하였다. 두 균주에 의해 PD, PT계 ginsenoside의 변화가 다르게 나타났지만 PD/PT비는 동일하게 58.4%씩 각각 높아졌다. 인삼의 총 사포닌 함량은 F. solani에 의해 17.8%, P. cactorum에 의해서 2.5%씩 각각 감소하였다.

It has generally been accepted that quality of ginseng should be determined not by the content of a single component but by composition and balance of total active principles. However, there still can be an exception with a product in which a given ginsenoside is used for the treatment of a specific disease. Although ginsenosides have been regarded to be major active components of ginseng and employed as index components for the quality control, it does not consistent with the traditional concept on ginseng quality creterion; main root has been more highly appreciated than the lateral or fine root. Content of ginsenosides in the lateral or fine root is much higher than that in main root. However, the ratio of protopanaxadiol (PD) and protopanaxatriol (PT) saponins existing in various part of ginseng root is greatly different. The ratio of PD/PT saponins in main root is well balanced but the thinner the root is the higher the ratio. Thus far, a total of 34 different kinds of ginsenosides have been isolated from Korean (red) ginseng, and their pharmacological activities were elucidated partly. Interestingly, different ginsenoside shows similar or contrary effects to each other in biological systems, thus indicating the significance of absolute content of single ginsenoside as well as compositional patterns of each ginsenoside. Therefore, pharmacological activities of ginseng should be determined as a wholly concept. In these regards, standardization of ginseng material (fresh ginseng root) should be preceded to the standardization of ginseng products because ginsenoside content and non-saponin active principles such as polysaccharides and nitrogen (N)-containing compound including proteins are significantly different from part to part of the root. In other words, the main root contains less ginsenosides than other lateral or fine roots. Contents of polysaccharides and N-containing compound in main root is higher. However, the quality control of ginseng products focused on non-saponin compounds has limitation in applying to the analytical method, because of the difficult chemical analysis of these compounds. Content of ginsenosides, and ratios of PD/PT and ginsenoside Rb,/Rg, are inversely proportional to the diameter of ginseng root. Therefore, these can be served as the chemical parameters for the indirect method of evaluating from what part of the root does the material originate. Furthermore, contents of polysaccharides and N-containing compounds show inverse relationship to saponin content. Therefore, it seems that index for analytical chemistry of saponin can be applied to the indirect method of evaluating not only saponin but also non-saponin compounds of ginseng. From these viewpoints, it is strongly recommended that quality of ginseng or ginseng products be judged not only by the absolute content of given ginsenoside but also by varieties and compositional balance of ginsenosides, including contents of non-saponin active principles.

본 연구는 인삼 잎의 이용증대를 위해 마이크로웨이브에 의한 인삼 잎의 잔류농약 추출효과와 발효 인삼 잎의 ginsenoside 유용 유도체의 전환 검토 및 품질 특성을 분석 하였다. 인삼 잎에 잔류되어 있는 tolclofos-methyl와 azoxystrobin을 microwave로 추출하기 위한 용매는 hexane이 가장 효율적 이었다. tolclofos-methyl와 azoxystrobin이 잔류되어 있는 인삼 잎에서의 microwave를 이용한 추출 최적 조건은 power 50~95 watts, 추출용매는 hexane, 추출시간은 3분으로 나타났다. 인삼 잎 추출물의 발효에서 발효전과 비교하여 $Rg_1$과 $Rb_1$은 감소한 반면 $Rh_1$, $Rg_3$, $Rk_1$ 및 $Rh_2$는 발효 후 모두 증가한 것으로 나타났다. 특히 홍삼에서 대표적인 성분으로 알려져 있는 $Rg_3$의 경우 발효전 $2.77{\mu}g/g$에서 발효 후 균주의 종류에 따라 $70.62{\sim}77.61{\mu}g/g$으로 증가하였다. 7일간 발효 후 인삼 잎의 총 페놀성 화합물 및 전자공여능은 일부 균주에서는 발효전과 비교하여 감소하다가 다시 증가하는 경향을 나타내었으나, 발효가 진행됨에 따라 전반적으로 감소되는 경향을 나타내었다.
