Objective: To investigate the chemical components 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: Ten compounds were isolated and elucidated as syringic acid (1), syringaldehyde (2), vanillic acid (3), 3-hydroxy-vanillic acid (4), 3, 4, 5-trimethoxy-phenol (5), 4-hydroxy-3,5-dimethoxy-phenol (6), 4-methoxy-benzaldehyde (7), 7-hydroxy-5-methoxy-chromone (8), crocin-1 (9), crocin-2 (10).
Conclusion: Compounds 2, 4 - 8 are first isolated from this plant.
