[Study on Phenylpropanoids of Gardenia jasminoides].

OBJECTIVE

To investigate the phenylpropanoids constituents of Gardenia jasminoides.

METHODS

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

RESULTS

Eight compounds were isolated from Gardenia jasminoides, including 4-hydroxy-cinnamic acid methylester (1), 3, 5-dimethoxy-4-hydroxy-cinnamic acid methylester (2), pisoninol II (3), 7-hydroxy-orebiusin A (4), (E) -3-(4'-hydroxyphenyl) -acrylic acid n-butyl ester (5), (E) -3-(4'-methoxyphenyl) -acrylic acid n-butyl ester (6), 4-methoxyl-phenylpropanol n-butyl ether (7) and cycloolivil (8).

CONCLUSION

All compounds are firstly isolated from this plant.
