分别为儿茶素[(+)-catechin

表儿茶素[(-)-epicatechin

12-烯-3β-齐墩果烷(9

12-diene-3β-hydroxyolean

β-谷甾醇(β-sitosterol

油酸(oleic acid

triptohypol F(6)

wiforsinsine B(7)。结论: 化合物 5

7 为首次从苦皮藤根皮中分离得到

化合物 6

7 为首次从南蛇藤属中分离得到。

Abstract

Objective: To study the chemical constituents from the petroleum ether extract of the root barks of Celastrus angulatus. Method: Petroleum ether extraction was dissolved in 80% methanol and extracted with petroleum ether. The compounds were isolated and purified by column chromatography

recrystallization and preparative HPLC. Their structures were identified by NMR spectra and references. Result: Seven compounds were obtained and identified as (+)-catechin(1)

(-)-epicatechin(2)

3β-hydroxyolean-9

12-diene(3)

β-sitosterol(4)

oleic acid(5)

triptohypol F(6)

and wilforsinine B(7). Conclusion: Compounds 5

7 were isolated from the root barks of C. angulatus for the first time. Compounds 6 and 7 were isolated from genus Celastrus for the first time.
