目的]明确海南油楠叶的化学成分。方法]采用硅胶柱色谱对海南油楠叶的正己烷提取物和醋酸乙酯提取物进行分离,根据理化性质及波谱分析确定结构。结果]分离得到9个化合物,鉴定为木栓酮(1)、3β-3-壬氧基-12-齐墩果烯(2)、8R,9R-环氧-β-石竹烯(3)、蒲公英萜醇(4)、豆甾烷-5烯-3-醇(5)、麦角甾-5-烯-3-醇(6)、2α,3β,-二羟基-24-去甲基-4(23)-12-齐墩果烯(7)、齐墩果酸(8)和邻苯二甲酸二戊酯(9)。结论]化合物1~9均为首次从该植物的树叶中分离得到。

Research on the Chemical Constituents in Leaf of Sindora glabra Merr. ex De Wit.

Objective] The chemical constituents in Sindora glabra Merr. ex De Wit. leaf was analyzed. Method] The Hexane and ethyl acetate extracted from the leaves were isolated and purified with silica gel column chromatography and the structure of the extracts was elucidated based on their physicochemical property and spectroscopic analysis. Result] Nine compounds: friedelin,3β-3-nonyloxy-12-oleanen,8R,9R-epoxy-β-carophyllene, Taraxero, stigmastane-5-ene-3-ol, ergosta-5-ene-3-ol, 2α, 3β,-dyhydroxyl-24-methyl-4(23)-12-oleanen,oleanolic acid and di-amyl phthalate,were isolated. Conclusion] The compounds: friedelin, 3β-3-nonyloxy-12-oleanen, 8R, 9R-epoxy-β-carophyllene, taraxero, stigmastane-5-ene-3-ol,ergosta-5-ene-3-ol, oleanolic acid, and diamyl phthalate are firstly isolated from Sindora glabra Merr. ex De Wit.
