摘要
从栗柄金粉蕨( Onychium lucidum ) 地上部分的甲醇抽提物中分到10 个成分, 经详细的一维、二维核磁数据分析, 它们被鉴定为: 木犀草甙(1) , 3 , 7 - 二甲基槲皮素(2) , 高山甙B (3) , 金粉蕨素(4) , 栗柄醇(5) , 金粉蕨醇B(6) , β- 谷甾醇(7) , 胡萝卜甙(8) ,齐墩果酸(9) 和蔗糖(10) 。栗柄醇系新成分。1 , 2, 9 系首次由金粉蕨属分到。
Ten compounds were isolated from the methanolic extract of the aerial parts of Onychium lucidum These compounds were identified as luteoloside(1), 3,7-dimethylquercetin(2), contigoside B(3), onychin(4), lucidol(1β-methoxy-2β,3α,4β,5α,6β-pentahydroxycyclohexane)(5), onychiol B(6),β-sitosterol(7), daucosterol(8), oleanolic acid(9) and sucrose(10). Compound 5 is a new constituent, while 1, 2 and 9 were isolated from the genus Onychium for the first time. Their structures were elucidated on the basis of detailed spectroscopic analysis, in particular, two-dimensional NMR( 1H- 1H COSY; 1H- 1H NOE; 1H- 13 C COSY, COLOC)data.
