通过硅胶和葡聚糖凝胶LH-20柱色谱分离纯化,得到了粗裂地钱中的三种黄酮化合物:4′,5,6-三羟基-3′,7-二甲氧基黄酮(1),5,7,4′-三甲氧基黄酮(2)和5,7,4’-三羟基黄酮(3)。三种黄酮的分子结构由质谱和核磁共振鉴定,其中4′,5,6.三羟基.3′,7-二甲氧基黄酮和5,7,4′.三甲氧基黄酮为首次从粗裂地钱中分离得到。关键词:粗裂地钱;4’,5,6.三羟基-3′,7-二甲氧基黄酮;5,7,4'-三甲氧基黄酮;5,7,4'-三羟基黄酮
Three flavonoids were isolated from Marcha tiazmc by chromatography on silica gel column and Sephadex LH- 20 column. The obtained compounds were identified as 4′, 5,6-trihydroxyl-3′, 7-dimethoxyflavone ( 1 ), 5,7,4′-trimethoxyflavone (2), 5,7,4′-trihydroxylflavone (3) by analysis of their ESI-MS, 1H and 13 C NMR. 5,7,4′-Trimethoxyflavone and 4′,5,6-Trihydroxyl-3′ ,7-dimethoxyflavone were first obtained from Marcha tiazmc.
