Objective:
To study the constituents of the stems of Periploca forrestii.
Method:
The compounds were separated and purified by silica gel column chromatography, recrystallization and high-performance liquid chromatography. The structures were identified by various spectroscopic methods.
Result:
Nine compounds were isolated and identified as 3-O-acetyloleanolic acid (1), 14-ursen-3-ol-1-one (2), taraxasterol (3), jacoumaric acid (4), periplogenin (5), 2alpha,3beta-dihydroxyursolic acid (6), E-p-hydroxy-cinnamic acid (7), caffeic acid (8), proanthocyanidin A2 (9).
Conclusion:
All compounds except 6 were isolated from this plant for the first time, compound 4, 9 were obtained from the Periploca for the first time.
