Chemical constituents of monoterpenes in fruits of Gardenia jasminoides / 中草药

ABSTRACT

Objective: To investigate the chemical constituents of monoterpenes in the fruits of Gardenia jasminoides. Methods: Various column chromatographies were used in the isolation and purification, and the physicochemical constant determination and spectral analysis were adopted to identify the chemical structures of monoterpenes. Results: Twelve monoterpenes were isolated from G. jasminoides, such as jasminoside B (1), jasminoside G (2), jasminodiol (3), crocusatin-C (4), (7S)-6-(hydroxymethyl)-1, 1, 5-trimethylcyclohex-3-enone (5), bornyl-6-O-β-D-xylopyranosyl-β-D-glucopyranoside (6), (10R, 11R)-gardendiol (7), (10S, 11S)-gardendiol (8), (5S, 9S)-gardenate A (9), (5R, 9R)-gardenate A (10), jasminoside E (11), and 5, 6-dihydroxymethyl-1, 1-dimethylcyclohex-4-enone (12). Conclusion: Compounds 5, 6, 8, 10, and 12 are first isolated from this plant.
