目的:研究大叶南五味子果实的化学成分。方法:采用硅胶柱层析、Sephadex LH-20、HPLC等色谱技术进行分离纯化,NMR和EI-MS等波谱学方法进行结构鉴定,结果:从中分离得到9个化合物,分别鉴定为:4,5-二羟基-3-甲氧基二苯(Ⅰ)、eriobofuran(Ⅱ)、3β,16β-二羟基-12-烯-乌苏烷(Ⅲ)、2α,3β,6β,23-tetrahydroxy urs-12,18-dien-28-oic acid(Ⅳ)、2α,3β,23-trihydroxy urs-12-en-28-oic acid(Ⅴ)、芦丁(Ⅵ)、2-乙基己酸(Ⅶ)、2-月桂酸单甘油酯(Ⅷ)、单蓖麻油酸甘油酯(Ⅸ)。结论:以上9个化合物均为首次从南五味子属植物中分离得到。
Objective:To study the chemical constituents from the fruits of Kadsura marmorata.Methods:The chemical constituents were isolated and purified by chromatography on silica gel,Sephadex LH-20 column and HPLC. Results:9 compounds were isolated and identified as 4,5-dihydroxy-3-methoxybiphenyl(Ⅰ),eriobofuran(Ⅱ),3β,16β-dihydroxy urs-12-ene(Ⅲ),2α,3β,6β,23-tetrahydroxy urs-12,18-dien-28-oic acid(Ⅳ),2α,3β,23-trihydroxy urs-12-en-28-oic acid(Ⅴ),rutin(Ⅵ),2-ethylhexanoic acid(Ⅶ),2-monolaurin(Ⅷ),glyceryl monoricinoleate(Ⅸ) on the basis of NMR and EI-MS spectroscopic analysis.Conclusion:All these compounds are isolated from this genus for the first time.
