茉莉根化学成分研究

Studies on the Chemical Constituents of the Root of Jasminum sambac

目的研究茉莉根Jasminumsambac(L.)Aiton的化学成分。方法采用溶剂萃取和柱色谱方法分离纯化,根据理化性质和光谱数据确定所得化合物的结构。结果从茉莉根的乙醇提取物中分离得到5个化合物,分别鉴定为:(+)-cycloo-livil(I),(+)-cycloolivil-4'-O-β-D-glucoside(II),iridanetriol(III),iridanetetraol(IV),β-胡萝卜苷(V)。结论化合物I、II为首次从素馨属分离得到,化合物III为首次从该植物分离得到。

Aim To study the chemical constituents in the roots of Jasminum sambac （ L. ） Aiton. Methods The chemical components were isolated by solvent extraction and column chromatography. The chemical structures were identified on the basis of physic-chemical constants and spectral data. Results Five compounds were isolated and identified as （ ＋ ） -cycloolivil （ Ⅰ ）, （ ＋ ） -cycloolivil-4＇-O-β-D-glucoside （ Ⅱ ）, iridane triol （ Ⅲ ）, iridane tetraol （Ⅳ）, β-daucostedo （Ⅴ）. Conclusion Compound Ⅰ and Ⅱ were isolated from genus Jasminum for the first time, and compound Ⅲ was isolated from this olant for the first time.
