Abstract
산양삼은 식품 또는 약초로써 많이 사용되고 있다. 이번 연구의 목표는 high performance liquid chromatography (HPLC) - charged aerosol detection (CAD)에 의해 산양삼의 추출물에 사포닌들의 분석을 최적화 하는 것이다. CAD는 물리적인 특성은 물론이고 입자크기, 스펙트럼 특성과는 무관하게 비휘발성 물질도 분석할 수 있다. 산양삼 추출물 중 Gensenoside Rb1, Rd, Rg1, Rf, Re 및 Rh1을 분석하였다. HPLC-CAD분석을 위한 사포닌 추출물은 건조 산양삼 10 g에 95% 에탄올 100 ml을 넣어 80℃에서 24시간 동안 추출하여 사포닌을 얻었다. 6개의 주요한 사포닌을 정량화하였을 경우 값은 다음과 같다. 사포닌들의 함량은 Rb1 (5.48±0.12 mg/g), Rd (5.33±0.14 mg/g), Rg1 (12.80±0.05 mg/g), Rf (19.08±0.68 mg/g), Re (19.87± 0.05 mg/g), 및 Rh1 (16.47±0.16 mg/g)로 확인하였다. 대체적으로 산양삼 추출물의 사포닌은 protopanaxatriol (Rg1, Rf, Re, Rh1)의 값이 protopanaxadiol (Rb1, Rd)보다 높게 확인 되었다. 이번 연구에서는 산양삼 사포닌의 분석조건을 HPLC-CAD를 이용하여 최적화하였고 제품화를 위해 약리활성에 관한 연구도 매우 중요할 것이다. Cultivated wild ginseng is a widely used dietary supplement and medicinal herb. The aim of this study was to optimize the ginseng using high performance liquid chromatography (HPLC)- charged aerosol detection (CAD) for ginsenoside analysis. CAD measures the physical property of an analyte and responds to almost all non-volatile species, independent of their nature, spectral properties, or particle size. It has become widely employed in pharmaceutical analysis. The cultivated wild ginseng extracts were analyzed for compositions of ginsenosides Rb1, Rd, Rg1, Rf, Re, and Rh1. The optimal analysis condition was set up from an experiment using a gradient. Ten grams of cultivated wild ginseng were extracted with 95% EtOH 100 ml for 24 hr at 80℃. The contents of the 6six major ginsenosides in the cultivated wild ginseng extract were Rb1 (5.48±0.12 mg/g), Rd (5.33±0.14 mg/g), Rg1 (12.80± 0.05 mg/g), Rf (19.08±0.68 mg/g), Re (19.87±0.05 mg/g), and Rh1 (16.47±0.16 mg/g), respectively. HPLC showed that the protopanaxatriol group (Rg1, Rf, Re, Rh1) had more content than the protopanaxadiol group (Rb1, Rd) in cultivated wild ginseng extract. In summary, the ginsenosides were identified with HPLC-CAD analysis, and their presence and quantity imply the importance of quality control, as well as the pharmacological activity of the ginseng root.
