OBJECTIVE:To study the chemical constituents of the flower of Zang Epipremnum aureum. METHODS:The con-stituents of ethyl acetate extract of the flower of E. aureum were separated and purified with varied chromatographic techniques, and the structures were identified based on spectral data and chemical properties. RESULTS:Ten compounds were isolated from eth-yl acetate extract of the flower of E. aureum,they were identified as rutamontine(1),edgeworoside C(2),edgeworin(3),tiliro-side (4),helichrysoside (5),kaempferol (6),2,4-dihydroxypheny-2-hydroxy-4-metho-xybenzyl-ketone (7),ethyl caffeate (8), phthalic acid bis-(2-ethyl-hexyl) ester (9) and noreugenin (10). CONCLUSIONS:Compound 7 is firstly isolated from natural source,compounds 5,8 and 9 is firstly isolated from the family Thymelaeaceae,compound 6 is firstly isolated from Edgeworthia and compound 2 and 10 are firstly isolated from the flowers of E. aureum. The study lays certain foundation for the quality evalua-tion of E. aureum.%目的:研究藏药绿萝花的化学成分。方法:采用多种柱色谱对绿萝花乙酸乙酯粗提物进行分离纯化,根据理化性质和波谱数据分析鉴定化合物结构。结果:从绿萝花乙酸乙酯粗提物中分离得到10个化合物,分别鉴定为Rutamontine(1)、结香苷C (2)、结香素(3)、银锻苷(4)、Helichrysoside(5)、山柰酚(6)、2,4-Dihydroxypheny-2-hydroxy-4-methoxybenzyl-ketone(7)、咖啡酸乙酯(8)、Phthalic acid bis-(2-ethyl-hexyl)ester(9)、去甲基丁香色原酮(10)。结论:化合物7为首次从植物来源分离得到,化合物5、8和9为首次从瑞香科植物分离得到,化合物6为首次从结香属分离得到,化合物2、10为首次从绿萝花分离得到。本研究为绿萝花质量评价奠定了一定基础。
