HPLC에 의한 미량 Ginsenoside의 분석법을 확립하고자 연구를 수행하였던 바, 그 결과를 요약하면 다음과 같다. 인삼 ginsenosid의 분석은 많이 시도되어 왔으나 주요 사포닌 및 미량 사포닌의 분석법이 정립되지 않고 있는 실정인바, 본 연구에서는 이동상 용매의 기울기 용리를 다양하게 변화를 주어 Rb1, Rb2, Rb3, Rc, Rd, Re, Rf Rg1, Rg2, Rg3, Rh1, Rh2의 총 12종의 사포닌을 양호하게 분리하는데 성공하였다. 이동상의 흐름 속도는 1.00ml/min이고 column온도는 35˚C, UV detector의 파장은 203nm로 모두 일정하게 한 결과였으며, 최적의 분석조건은 H2O와 CH3CN의 용매 조성이 82/18, 70/30, 55/45, 50/50으로 각각의 ginsenosides의 안정적인 Area 값을 얻을 수 있었고 재현성을 시도해본 결과, 반복간 편차가 적어 재현성이 매우 양호한 것으로 나타났다.

This study investigated the distributive property of micropollutants in sediment around Gwang-yang bay using simultaneous analytical method of 310 chemicals. In the results, the major micropollutants detected were CH type chemicals such as aliphatic, polycyclic compounds, benzenes, and CHN(O) type chemicals aromatic amines, and pesticides. Insecticides of pesticide type were frequently detected at all sampling site. The total concentration of micropollutants were higher in summer than in winter and measured within the range of ND ～ 36.50㎍/L. Also, because of effect of seomjin river, GY6 of all sampling site detected by the highest concentration, GY10 and 11 located in Gwang-yang outside bay were not detected the micropollutants. From the result of this study, we should estimated that the industrial complex located in Gwang-yang inside bay and an inflow of fresh water through the Seomjin river are major pollution sources of Gwang-yang bay.

In this study, we try to determine the distributive property in southwest coastal waters, such as Kwang-yang bay, Ka-mak bay, Yeo-ja bay, Wan-do, Hea-nam, Young-gwang, and Mok-po, using simultaneous analytical method of 310 chemicals. The results were detected tens of the organic pollutants in sampling sites, and the major chemicals detected were CH type chemicals such as aliphatic, polycyclic compounds and were CHN(O) type chemicals such as aromatic amines, nitro compounds. In particular, pesticides were mainly detected in summer, phenols and phthalate esters were not seasonal effect. Also, a number of aromatic chemicals were detected in Kwang-yang bay. From the results of this study, we confirmed that it is mainly contaminated in summer and the pesticide chemicals are the major pollutants in southwest coastal waters.
