摘要
目的:研究宾川獐牙菜的化学成分。方法:用系统溶剂提取,常规方法进行分离纯化,根据化合物的理化性质以及~1H-NMR、^(13)C-NMR等波谱鉴定化合物的结构。结果:从宾川獐牙菜中分离得到7个化合物,分别鉴定为:1,2,3,4-四氢-1,4,8-三羟基-6-甲氧基酮(Ⅰ)、红白金花内酯(Ⅱ)、1-O-β-D-吡喃葡萄糖-1,2,3,4-四氢-4,8-二羟基-6-甲氧基酮(Ⅲ)、山楂酸(Ⅳ)、1-羟基-3,7-二甲氧基酮(Ⅴ)、1,8-二羟基-3,5-二甲氧基酮(Ⅵ)、1,7-二羟基-3,4,8-三甲氧基酮(Ⅶ)。结论:所有化合物均为首次该植物中分离得到。
Objective: To study the chemical constituents of Swertia binchuanensis. Methods: The constituents were separated and purifyed by conventional methods. Their structures were identified on the basis of spectral analysis such as -1H-NMR,-(13)C-NMR. Results:Seven compounds were isolated and identified as 1,2,3,4-tetrahydro-1,4,8-trihydroxy-6-methoxyxanhone( Ⅰ),erythrocentaurin( Ⅱ),1-O-β-D-glucopyranosyl-1,2,3,4-tetrahydro-4,8-dihydroxy-6-methoxyxanthone( Ⅲ),maslinic acid( Ⅳ),1-hydroxy-3,7-dimethoxyxanthone( Ⅴ),1,8-dihydroxy-3,5-dimethoxyxanthone( Ⅵ),1,7-dihydroxy-3,4,8-termethoxyxanthone( Ⅶ). Conclusion: All compounds were isolated from Swertia binchuanensis for the first time.
