[Study on chemical constituents of the ethyl acetate extract from Blumea aromatica].

To study the chemical constituents of the ethyl acetate extract from Blumea aromatica. Column chromatographic techniques were used for the isolation and purification. Spectroscopic techniques were used for the identification of structures. Seven compounds were isolated from the ethyl acetate extract of 80% alcohol extract of the whole plant, and their structures were identified as xanthoxylin(1), dibutyl phthalate(2), luteolin-3',4',7-trimethyl ether(3), rubiadin(4), eriodictyol(5), kaempherol(6), luteolin 7,3'-dimethyl ether(7). All the compounds are isolated from this plant for the first time. Among them, compounds 2,4 and 7 are isolated from this genus for the first time.
