Abstract

This study was conducted to analyze not only for the quality guaranteed of red ginseng but also for the minor ginsenosides. Although several studies have reported to analyze ginseng saponins, those were focused to major saponins, including 6 to 7 ginsenosides. As increase of interest in medicinal effect of ginseng products, anasis of various ginsenosides in both red and white ginseng are strongly demanded. To perform optital condition of 12 ginsenoside analysis, We controlled HPLC conditions, such as the gradient elution of the mobile phase. We found the adequate separation method for 12 ginse-nosides. The optimum condition was as following : H$_2$O/CH$_3$CN ratios were 82/18, 70/30, 55/45 and 50/50, respectively. Sol-vent flow rate was 1.00 ma/min. Column temperature was kept to 35$^{\circ}$C. UV detector was set to 203 nm.

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 Rb$_1$, Rb$_2$, Rb$_3$, Rc, Rd, Re, Rf Rg$_1$, Rg$_2$, Rg$_3$, Rh$_1$, Rh$_2$의 총 12종의 사포닌을 양호하게 분리하는데 성공하였다. 이동상의 흐름 속도는 1.00ml/min이고 column온도는 35$^{\circ}$C, UV detector의 파장은 203nm로 모두 일정하게 한 결과였으며, 최적의 분석조건은 H$_2$O와 CH$_3$CN의 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.
