Objective:
To study the triterpenoids from the fruits of Ligustrum lucidum.
Methods:
The constituents were extracted with 95% EtOH, partitioned with different solvents, isolated and purified by silica gel, Sephadex LH-20 and PHPLC column chromatography. The structures were elucidated by physicochemical properties and spectroscopic data.
Results:
Thirteen compounds were isolated and identified as methyl oleanolate (1), 3-O-acetylursolic acid (2), 3-ketooleanolic acid (3), 19alpha-hydroxyl ursolic acid (4), lupeol (5), 3-O-acetyl oleanolic acid (6), oleanolic acid (7), betulin (8), ursolic acid (9), fouquierol (10), 19alpha-hydroxyl acetylursolic acid (11), 3-O-cis-P-coumaroyl maslinic acid (12) and 3-O-trans-P-coumaroyl maslinic acid (13).
Conclusion:
Compounds 1 - 4 are obtained from this plant for the first time.
