摘要
目的:研究蜜柑草正丁醇部位的化学成分。方法:利用柱色谱分离技术,对蜜柑草75%乙醇提取物的正丁醇萃取部位进行分离纯化,并通过1H-NMR、13C-NMR、MS等波谱技术进行结构鉴定。结果:从蜜柑草正丁醇部位中分离得到6个化合物,分别鉴定为:鞣花酸(1)、叶下株乙素(2)、叶下株丙素(3)、花椒素(4)、橙皮素-7-O-[(α-L-吡喃鼠李糖基(6→1)]-β-D-吡喃葡萄糖苷(5)、4-O-甲基没食子酸(6)。结论:其中,化合物2~6为首次从该植物中分离得到。
Objective: To study the chemical constituents of n-BuOH extract from Phyllanthus matsumurae.Methods: Column chromatography was used for the isolation and purification.Spectroscopic methods including1H-NMR,13C-NMR and MS were used for the identification of structures.Results: Six compounds were isolated from the n-BuOH extract of 75% alcohol extract of the whole plant and identified as ellagic acid( 1),phyllanthuspermin B( 2),phyllanthuspermin C( 3),xanthoxylin( 4),hesperetin-7-O-[6-O-( α-L-rhamnopy ranosyl) ]-β-D-glucopyranoside( 5) and 4-O-methylgallic acid( 6).Conclusion: Compounds 2 ~ 6 are obtained from this plant for the first time.
