摘要: 从月腺大戟(Euphorbia ebracteolata Hayata)的干燥根中首次分得4种萜类化合物,根据理化数据和光谱分析,鉴定其中2种为新的二萜内酯,分别命名为月腺大戟甲素(ebracteolatanolide A)和月腺大戟乙素(ebracteolatanolide B),另2种为已知化合物Jolkinolide B和3-乙酰α香树脂醇。Abstract: Euphorbia ebractolata has been used as insecticide and tuberculocide. Four crystalline compounds were isolated from the root of this plant. They were characterized by their physico-chemical properties and spectral data as: 3-acety α-amyrin (I), Jolkinolide B (II), ebracteolatanolide A (III) and ebracteolatanolide B (IV). I and II were isolated for the first time from E.ebracteolata Hayata. III and IV are new compounds.
