Title: Chemical constituents from Hypericum pseudohenryi
Abstract: Objective To study the chemical constituents of Hypericum pseudohenryi. Methods The chemical constituents were isolated and purified by various column chromatographic methods. Their chemical structures were identified by physicochemical properties and spectral analyses. Results Twenty-one compounds were isolated from the acetone extract and identified as 3, 4-O-isopropylidenyl shikimic acid(1), shikimic acid(2), protocatechuic acid(3), caffeic acid(4), benzoic acid(5), chlorogenic acid(6), methyl chlorogenate(7), 1, 3, 6, 7-tetrahydroxyxanthone(8), 4-hydroxy-2, 3-dimethoxyxanthone(9), 1, 5-dihydroxy-2- methoxyxanthone(10), C-3/C-8″ biapigenin(11), kaempferol(12), quercetin(13), quercitin(14), quercetin-3-O-β-D- arabinopyranoside(15), hyperin(16), isoquercitrin(17), loliolide(18), farrerol(19), 1-monopalmitin(20), and β-sitosterol(21). Conclusion All compounds are isolated from this endemic plant for the first time, and compounds 18 and 20 are isolated from the plants of Hypericum Linn. for the first time.
