目的研究滇白珠(Gaultheria leucocarpa var.yunnanensis or var.crenulta)地上部分的化学成分。方法应用各种色谱技术进行分离纯化,用MS和NMR分析鉴定化合物结构。结果分离得到7个化合物,分别鉴定为①槲皮素-3-O-β-D葡萄糖醛酸苷、②山萘酚-3-O-β-D-葡萄糖醛酸苷、③龙胆酸甲酯、④水杨酸甲酯、⑤白珠树苷、⑥滇白珠素A、⑦滇白珠素B。结论化合物1~3是首次从该植物中分离得到。
Objective To study the chemical components of aerial parts of Gaultheria leucocarpa var.yunnanensis or var.crenulta. Methods A variety of chromatographic techniques were used for separation and purification. The structures of the compounds were identified by MS and NMR analysis. Results Seven compounds were isolated and identified as 1 quercetin-3-O-β-D glucuronide, 2 kaempferol-3-O-β-D-glucuronide, 3 gentisic acid A Ester, 4 methyl salicylate, 5 white sarcosin, 6 white cyclin A, 7 white cyclamate B. Conclusion Compounds 1-3 were isolated from this plant for the first time.
