摘要
目的研究灰毛浆果楝Cipadessa cinerascens茎的化学成分。方法采用正、反相硅胶柱色谱与Sephadex LH-20凝胶柱色谱进行分离纯化,并运用各种波谱方法对分离的化合物进行结构鉴定。结果从灰毛浆果楝茎中分离得到17个化合物,分别鉴定为羊毛甾-7-烯-3-酮-22,25-环氧-23,24-丙酮乙缩醛(1)、chisopanin M(2)、3β-羟基-5-烯-豆甾(3)、7α-羟基-4-烯-3-酮-豆甾(4)、3β-羟基-5-烯-7-酮-豆甾(5)、7α-羟基-谷甾醇(6)、22E-7α-甲氧基-5α,6α-环氧-8(14),22-二烯-3β-羟基麦角甾(7)、7β-羟基-4-烯-3-酮-胆甾(8)、3β-乙酰氧基-2β,4β-二羟基-16-酮-孕甾(9)、17α,20R-二羟基-3,16-二酮-孕甾(10)、2β,3β-二羟基-16-酮-孕甾(11)、3β,7α-二羟基-20-酮-孕甾(12)、2α,3β-二羟基-5-烯-20-酮-孕甾(13)、1,4-二烯-3,16-二酮-2-羟基雄甾(14)、5-烯-17-酮-3β,16β-二羟基雄甾(15)、芹菜素(16)和annuionone D(17)。结论除化合物14和17外,其余化合物均为首次从灰毛浆果楝中分离得到。
Objective To study the chemical constituents from the stems of Cipadessa cinerascens.Methods The constituents were separated by column chromatography and their structures were elucidated by spectral data analyses.Results Seventeen chemical constituents were isolated from the Et OAc extract in the stems of C.cinerascens and their structures were identified as lanost-7-en-3-one-22,25-epoxy-23,24-acetone acetal(1),chisopanin M(2),3β-hydroxy-5-enstigmast(3),7α-hydroxy-4-en-3-one-stigmast(4),3β-hydroxy-5-en-7-one-stigmast(5),7α-hydroxysitosterol(6),22E-7α-methoxy-5α,6α-epoxy-8(14),22-dien-3β-hydroxy-ergosta(7),7β-hydroxy-4-en-3-one-cholest(8),3β-acetyloxy-2β,4β-dihydroxy-16-one-pregnan(9),17α,20R-dihydroxy-3,16-dione-pregnan(10),2β,3β-dihydroxy-16-one-pregnan(11),3β,7α-dihydroxy-20-onepregnan(12),2α,3β-dihydroxy-5-en-20-one-pregnan(13),1,4-dien-3,16-dione-2-hydroxyandrosta(14),5-en-17-one-3β,16β-dihydroxyandrost(15),apegenin(16),and annuionone D(17).Conclusion All the compounds except 14 and 17 are obtained from this plant for the first time.
