摘要
用二维NMR技术 (HMBC和NOESY)研究了从药用冬青属植物满树星中分离出的一新 1 8,1 9 裂乌索酸型三萜皂甙 满树星甙I(aculeosideI) 。
A novel 18,19 seco ursane saponin, aculeoside I (1) was isolated from the leaves of Ilex aculeolata Nakai. 2D NMR methods were used to elucidate its chemical structure. The structure of the new saponin was determined as 3,19 dihydroxyl 16,21 epoxy 18,19 seco 13(18) urs ene 28 oic acid 19 O α L rhamnopyranosyl (1→2) α L arabinopyranoside.
