[Study on chemical constituents of Gardenia jasminoides(III)].

OBJECTIVE

To investigate the chemical constituents of Gardenia jasminoides fruits.

METHODS

Various column chromatography were used in the isolation and purification, and physiochemical constant determination and spectral analysis were adopted to determine the chemical structures.

RESULTS

Twelve compounds were isolated from Gardenia jasminoides including jasminoside I (1), gardenoside (2), gardaloside (3), 3-hydroxy-urs-12-ene-11-ketone(4), 5, 4'-dihydroxyl-7, 3', 5'-trimethoxyflavone (5), 5, 7, 3', 4', 5'-pentamethoxyflavone(6), 3, 5, 6, 4'-tetrahydroxy-3', 5'-dimethoxyflavone (7), shikimic acid (8), 1, 2, 4-benzenetriol (9), 3, 4-dimethoxy-benzoic acid (10), dibutyl phthalate (11) and diisobutyl phthalate (12).

CONCLUSIONS

Compounds 4 - 7 and 9 -10 were isolated from this plant for the first time.
