摘　　要：目的研究二蕊荷莲豆Drymariadiandra的化学成分。方法采用大孔树脂D-101,硅胶柱色谱和PR-18进行反复分离纯化,通过波谱分析方法鉴定化合物结构。结果分离并鉴定了2个化合物:6-羧甲基-5,7,4′-三羟基黄酮()和4[E],8[E]-N-[2′-D-羟基-十六烷酰基]-1-O-D-吡喃葡萄糖基-4,8-二烯-十八鞘氨醇(大豆脑苷,)。结论化合物为新化合物,化合物首次从该植物中分离得到。Objective To investigate the chemical costituents from Drymaria diandra. Methods Compounds were separated and purified by repeated column chromatographies on macroporous resin D-101, silica gel, and RP-18. Two compounds were identified by spectral analysis. Results Two com-pounds were isolated from D. diandra. Their structures were identified as 6-carboxymethyl-5, 7, 4′-trihy-droxyflavone ( ) and 1-O-β-D-glucopyranosyl-(2S, 3R, 4E, 8E)-Z-N-(2′-hydroxypalmitoyl) octadecas-phinga-4, 8-dienine (soya cerebroside , ). Conclusion Compound is a new compound. Compound is obtained from this plant for the first time.
