Abstract:
Objective: To study the chemical constituents from the cane of Pileostegia viburnoides. Methods: The compounds were isolated and purified by silica gel and Sephadex LH-20 column chromatography. Their structures were identified on the basis of their physicochemical properties and spectroscopic data. Results: Thirteen compounds were isolated from the cane of P. viburnoides and their structures were identified as friedelin (1), 3-oxo-nofriedelin-28-al (2), stigmast-4-en-3-one (3), stigmasterol (4), (24R)-5A- stigmastane-3, 6-dione (5), tetracosyl amine (6), ursolic acid (7), pomolic acid (8), oleanolic acid (9), umbelliferone (10), 4-hydroxymellein (11), cleomiscosin A (12), and daucosterol (13), respectively. Conclusion: Compound 6 is obtained as a natural product for the first time; Compounds 2-5, 7-9, 11, and 12 are obtained from this genus for the first time and all the compounds are obtained from P. viburnoides for the first time.
