[Studies on the chemical constituents of MEICHA (II)].
OBJECTIVE
To study the chemical constituents of MEICHA.


METHODS
Chromatography and spectroscopic analysis were employed to isolate and elucidate the chemical constituents in the plant.


RESULTS
Seven compounds were obtained and identified as beta3-sitosterol (I), oleanolic acid (II), quercetin (III), Taxifolin (IV), Catechin (V), Querceetin-3-O-alpha-L-rhamnoside (VI) and Gallic acid (VII).


CONCLUSIONS
Seven compounds are isolated from this plant for the first time.
