Triterpenoids constituents of whole plant of Lantana camara Linn / 中国药学杂志

ABSTRACT

OBJECTIVE: To study the chemical constituents of triterpenoids from Lantana camara Linn. METHODS: The compounds were isolated and purified by repeated column chromatography on silica gel, Sephadex LH-20 and ODS. Their structures were i-dentified by physicochemical properties and spectroscopic analysis. RESULTS: Eleven compounds were isolated and identified as lantadene A (1), lantadene B (2), oleanonic acid (3), lupeol acetate (4), 3β-acetyloleanolic acid (5), oleanolic acid (6), 3-O-acetyl pomolic acid(7), 3β, 25-epoxy-3α, 21α-dihydroxy-22β-angeloyloxyolean-12-ene-28-oic acid (8), betulinic acid (9), 2α, 3α, 19-trihy-droxy-12-en-28-ursolic acid(10), 22-oxo-3β, 24-dihydroxyolean-12-ene(11). CONCLUSION: Compounds 4, 5, 7-11 are isolated from this plant for the first time.
