目的研究太白山地区白檀(Symplocos paniculata)的化学成分。方法采用硅胶柱色谱、Sephadex LH-20柱色谱,结合重结晶等方法分离纯化化合物,并通过化合物的理化性质和波谱数据鉴定其化学结构。结果从白檀中分离并鉴定了7个化合物,分别为β-豆甾醇(1)、蒲公英赛醇(2)、19-α-羟基-3-O-乙酰熊果酸(3)、熊果酸(4)、3-氧代-19α,23,24-三羟基熊果-12-烯-28-酸(5)、正三十碳酸(6)和胡萝卜苷(7)。结论这7个化合物均为首次从该植物中分离得到,其中化合物1,2,3,5,6和7为首次从该属植物中分离得到。
Objective To study the chemical constituents of Symplocos paniculata in Taibai Mountain. Methods The compounds were isolated and purified by column chromatography on silica gel, Sephadex LH-20 column and recrystallization. Their chemical structures were elucidated on the basis of physico-chemical properties and spectral data. Results Seven compounds were isolated from white sandalwood and identified as β-stigmasterol (1), dandelion alcohol (2), 19-α-hydroxy-3-O- (4), 3-oxo-19α, 23,24-trihydroxy bearberry-12-en-28-oic acid (5), n-trimelcarbonic acid (6) and daucosteride (7). Conclusion These seven compounds were isolated from this plant for the first time. Compounds 1, 2, 3, 5, 6 and 7 were isolated from this genus for the first time.
