Water-soluble constituents from of seeds Orychophragmus violaceus / 中国药学杂志

ABSTRACT

OBJECTIVE: To study water-soluble constituents from the seeds Orychophragmus violaceus. METHODS: The constituents were isolated and purified by silica gel chromatography repeatedly, and the structures were identified by spectral analysis and chemical methods. RESULTS: Fifteen water-soluble compounds were isolated from the seeds Orychophragmus violaceus and their structures were identified as blumenol A(1), 3', 5', 5, 7-tetrahydroxylflavanone(2), (+)-catechin(3), quercetin(4), adenosine(5), salicylic acid(6), 2'-deoxy adenosine(7), p-coumaric acid(8), vanillic acid(9), protocatechuic acid(10), caffeic acid(11), syringic acid(12), daucosterol(13), succinic acid(14) and azelaic acid(15). CONCLUSION: All compounds are isolated from Orychophragmus violaceus for the first time. This study can establish the foundation for the classification chemical composition this plant.
