Studies on Chemical Constituents of Gaultheria leucocarpa var. Yunnanensis (Franch.) T. Z. Hsu R. C. Fang

目的:研究滇白珠地上部分的化学成分.方法:质谱、核磁等鉴定结构.结果:从95%乙醇提取物的氯仿淬取相中获得4个化合物,正三十二烷酸及同系物(1),熊果酸(2),香草酸(3)和槲皮苷(4).结论:化合物1,4为首次从该植物中得到,化合物2和3为首次从地上部分得到.To separate and identify the chemical constituents of the aerial part of Gaultheria leucocarpa var. yunnanensis.The compounds were extracted with solvents, isolated by column chromatography and identified by spectral analysis.Four compounds were identified as n-dotriacontane and its homologous compound(1), ursolic acid(2), vanillic acid(3), and quercitrin(4).The compounds 1, 4 were obtained from the plant for the first time, and 2 and 3 were from above-ground part of the plant for the first time.PubMed中文核心期刊要目总览(PKU)中国科学引文数据库(CSCD)012844-8462
