[Studies on constituents in Uncaria macrophylla Wall].Zhongguo Zhong Yao Za Zhi. 2000 Aug; 25(8):484-5.ZZ
To study the chemical constituents of Uncaria macrophylla.
Compounds were isolated by Columu Chromatography, and the structures were identified by NMR spectral data and other methods.
RESULT AND CONCLUSION
Six compounds were isolated and identified as ursolic acid, 3 beta-6 beta-23-trihydroxyurs-12-en-28-oic acid, 3 beta, 6 beta, 19 alpha-trihydroxyurs-12-en-28-oic acid, epicatechin, beta-sitosterol and daucosterin. All the compounds were isolated for the first time from the plant.
