摘要
To study the chemical constituents,the ethanol extract of dried stem of Akebia quinata(Thunb.) Decne.was seperated by dichloromethane,n-butanol in sequence.The n-butanol extract was further isolated by D101 macroporous resin and silica gel column chromatography.A new triterpene with two known triterpenes were isolated,their structures were identified as 3α,24-dihydroxy-30-norolean-12,20(29)-dien-28-oic acid(Ⅰ),3α,24,29-trihydroxyolean-12-en-28-oic acid(Ⅱ),2α,3β,23-trihydroxyolean-12-en-28-oic acid(Ⅲ).The new compound Ⅱ was nominated as quinatic stem acid.The structures were identified and elucidated by physicochemical properties and spectral analysis.
