Abstract:
Objective: To study the chemical constituents of CHCl3 and EtOAc extracts from Oxytropis myriophy. Methods: The CHCl3 and EtOAc extracts of O. myriophy were isolated and purified by silica gel chromatography, Sephadex LH-20, and PTLC chromatography. The structures were identified by spectral methods. Results: Eleven compounds were obtained and identified from the CHCl3 and EtOAc extracts from O. myriophy, namely 5-hydroxyl-7,4'-dimethoxyflavone (1), 4-hydroxylacetophenone (2), 5,4'-dihydroxyl-7,3'-dimethoxyflavone (3), 5,7-dihydroxyl-6,4'-dimethoxyflavone (4), isorhamnetin (5), kaempferol (6), acetophenone- 4-O-β-D-glucoside (7), 2-hydroxyl-6-methoxyacetophenone-4-O-β-D-glucoside (8), 6-methoxycoumarin-7-O-β-D-glucoside (9), isorhamnetin-3-O-β-D-glucoside (10), and kaempferol-3-O-β-D-glucoside (11). Conclusion: All of the compounds are isolated from this plant for the first time and compound 1, 7, and 8 are isolated from the plants of Oxytropis DC. for the first time.
