Abstract
Eum Yang Kwak, the aerial part of Epimedium koreanum, is widely used as a folk medicine for stimulant in man, tonic, and hypotensive purpose. The plant contains icariin (a specific flavonoid), magnoflorine (an alkaloid) and tannin, but their contents are not known until now. In this paper, a quantitative analysis method for them was developed. Determination of icariin and magnoflorine was successfully achived by high performance liquid chromatography equipped with a UV detector in the ranges of
음양곽 성분 중에서 icariin, magnoflorine을 분리하고 이를 표준품으로 음양곽 추출액의 이들 성분에 대하여 HPLC를 이용한 정량법을 수립하였으며 이 성분들의 추출효율을 여러 가지 추출조건하에서 검토하고 그 함량을 분석 하였다. Icariin은 0.1-0.4 mg/ml 농도에서, magnoflorine은 0.02-0.1 mg/ml 농도에서 아래와 같은 조건으로 정량 분석하였다. Icariin의 HPLC조건 :칼럼, LiChrosorbRPl8; 용출용매, MeOH/water/acetic acid (60 : 40 : 0.5); 검출기, 자외부 흡광광도계; 측정파장, 270 nm; 주사량,
