摘要
目的:研究长梗南五味子藤茎的化学成分。方法:采用硅胶、Sephadex LH-20、半制备高效液相色谱等多种色谱技术进行分离纯化,通过波谱数据并结合文献鉴定化合物的结构。结果:从长梗南五味子藤茎的甲醇提取物中分离得到了7个化合物,分别鉴定为:longipedunin D(1)、renchangianin A(2)、renchangianin B(3)、meso-dihydroguaiaretic acid(4)、异落叶松脂素-9-O-β-D-木糖苷(5)、(-)-棓儿茶素(6)、(+)-儿茶素(7)。结论:其中,化合物1为新的木脂素类化合物,化合物2、3为首次从该植物中分离得到。
Objective： To investigate the chemical constituents from stems of Kadsura longipedunculata. Methods： The constituents were isolated and purified by various chromatographic methods,and their structures were elucidated by spectroscopic analysis and comparison with literatures. Results： Seven compounds were isolated from the stems of Kadsura longipedunculata and were identified as longipedunin D（ 1）,renchangianin A（ 2）,renchangianin B（ 3）,meso-dihydroguaiaretic acid（ 4）,isolariciresinol-9-O-β-D-xyloside（ 5）,（-）-gallocatechin（ 6） and（ ＋）-catechin（ 7）. Conclusion： Compound 1 is a novel lignan,and compounds 2,3 are isolated from this plant for the first time.
