摘要
从中国广西药用植物苍白秤钩风 (Diploclisiaglaucescens)藤茎的 95 %乙醇提取物中分离得到 5个脱皮甾酮类化合物 ( 1 5 )。通过NMR、MS以及化学沟通等方法分别将其结构鉴定为 paristeroneC 2 0 ,2 2 monoacetonide( 1) ,paristerone( 2 ) ,ecdysterone( 3) ,makisteroneC( 4 )和capisterone( 5 )。化合物 1为首次从自然界分得的天然产物 ,2 ,4 。
Five ecdysteroids were isolated from the EtOH extract of the stems of Diploclisia glaucescens. Their structures were identified as paristerone 20,22 monoacetonide(1),paristerone(2),β ecdysterone(3),makisterone C(4)and capitasterone(5),respectively,on the basis of chemical and physical evidence.This is the first report of paristerone 20,22 monoacetonide isolated from natural source.Compounds 2,4,and 5 were also isolated for the first time from D.glaucescens .
