Objective: To study chemical constituents of Gardenia jasminoides. Method: Silica gel and Sephadex LH-20 column chromatography were employed for the isolation and purification. The structures were identified on the basis of spectroscopic data and chemical methods. Result: Seven triterpenoids were identified as ursolic acid(1)
19α-hydroxy-3-acetylursolic acid (2)
isotaraxerol (3)
rotundic acid(4)
barbinervic acid (5)
clethric acid (6)
myrianthic acid (7)
respectively. Conclusion: Compounds 2-7 are reported from the genus Gardenia for the first time.
