Abstract
OBJECTIVE: To investigate the chemical constituents of Kochia scoparia. METHODS: The constituents of EtOAc-soluble portion were isolated and purified by silica gel column chromatography. Their structures were identified by spectral features. RESULTS: Twelve compounds were isolated and identified as tectorigenin (1), pratensein (2), 5,2'-dihydroxy-6,7-methylenedioxyisoflavone (3), iriflogenin (4), 5-hydroxy-6, 7-methylenedioxyflavone (5), fumalicacid (6), N-trans-feruloylmethoxytyramine (7), N-transferuloyltyramine (8), stigmasterol (9), oleanolic acid (10), beta-stigmasterol (11), daucosterol (12). CONCLUSION: compounds 1-9 are isolated from this plant for the first time.
