摘要:

目的:对药用植物双参的化学成分进行研究。方法:采用硅胶、Sephadex LH-20、ODS等多种柱层析方法对双参进行分
离纯化,采用现代波谱学技术对分离得到的化合物进行结构鉴定。结果:从双参地下部分的乙酸乙酯部位分离得到4个三萜
类成分,分别鉴定为3β,28-二羟基-乌苏烷(1)、3β,23-二羟基-12-烯-28-酸(2)、α-香树精(3)和3β-羟基-24-降-乌苏-4
(23),12-二烯-28-酸(4)。结论:这4 个三萜类成分首次从该药用植物中分离得到。

Abstract:

Objective: To study the chemical compositions of the Medicinal Plants Triplostegia glandulifera. Methods: The
compounds were isolated and purified by silica gel, Sephadex LH-20 and ODS column chromatography methods, and their structures
were identified by modern spectroscopy techniques. Results: Four trierpenoid compositions were isolated from ethyl acetate fraction of
the underground part of T. glandulifera and identified as 3β, 28-dihydroxy-ursane(1), 3β, 23-Dihydroxyurs-12-en-28-oic-acid
(2), α-Amirina(3), and 3β-hydroxy-24-nor-urs-4(23), 12-dien-28-oic acid(4). Conclusion: Four trierpenoid compositions
were isolated from this genus for the first time.

Key words: Triplostegia glandulifera, underground part, trierpenoid compositions
