白树的化学成分研究Ⅱ

Studies on chemical constituents of Suregada glomerulata Ⅱ

目的:研究白树Suregada glomerulata的化学成分。方法:采用硅胶,Sephadex LH-20,大孔树脂D101,ODS等柱色谱及重结晶等方法分离纯化,通过理化常数测定和光谱分析鉴定化合物的结构。结果:从中分离得到9个已知化合物分别为Jolkinolide B(1),8α,14-dihydro-7-oxo-jolkinolide E(2),泽漆内酯乙(3),ent-kauran-16β,17-diol(4),7-羰基-β-谷甾醇(5),东莨菪内酯(6),腺苷(7),1′-sinapoylglucose(8),蔗糖(9)。结论:化合物2～9为首次从该属植物中得到。

Objective： To study the chemical constituents of Suregada glornerulata. Method： Isolation and purification were carried out on silica gel, sephardex LH - 20, ODS column chromatography etc. Constituents were identified by physicochemical properties and spectral analysis. Result： Nine compounds, Jolkinolide B （1） , 8a, 14-dihydro-7-oxo-jolkinolide E （2）, helioscopinolide B （3）, entkauran-16β, 17-diol （4）, 7-oxo-β-sitosterol （5）, scopoletin （6）, adenosine （7）, 1＇-sinapoylglucose （8）, sucrose （9）, were obtained and identified. Conclusion： Compounds 2-9 were isolated from S. glomertdata for the first time.
