Three new megastigmane glucopyranosides, komaroveside A [(3S,4R,5Z,7E)-3,4-dihydroxy-5,7-megastigmadien-9-one-3-O-β-D-glucopyranoside] (1), komaroveside B [(3S,4S,5S,6R,7E)-5,6-epoxy-3,4-dihydroxy-7-megastigmen-9-one-3-O-β-D-glucopyranoside] (2) and komaroveside C [(3S,4S,5S,6R,7E,9S)-5,6-epoxy-3,4,9-trihydroxy-7-megastigmen-3-O-β-D-glucopyranoside] (3) were isolated, together with eight known compounds, from Cardamine komarovii. The identification of these compounds and the elucidation of their structures were based on 1D- and 2D-NMR spectral data analysis. The isolated compounds were tested for their cytotoxicity against four human tumor cell lines (A549, SK-OV-3, SK-MEL-2, HCT15) in vitro using the sulforhodamine B bioassay.
从荠菜中分离出三种新的麦角甾烷葡萄糖苷,即komaroveside A [(3S,4R,5Z,7E)-3,4-二羟基-5,7-麦角甾烷二烯-9-酮-3-O-β-D-葡萄糖苷] (1)、komaroveside B [(3S,4S,5S,6R,7E)-5,6-环氧-3,4-二羟基-7-麦角甾烷-9-酮-3-O-β-D-葡萄糖苷] (2) 和 komaroveside C [(3S,4S,5S,6R,7E,9S)-5,6-环氧-3,4,9-三羟基-7-麦角甾烷-3-O-β-D-葡萄糖苷] (3),以及八种已知化合物。这些化合物的鉴定及其结构的阐明是基于1D和2D-NMR光谱数据分析。分离出的化合物使用磺基罗丹明B生物测定法在体外测试了其对四种人类肿瘤细胞系(A549、SK-OV-3、SK-MEL-
