title: [Study on chemical constituents of Potentilla chinensis Ser].
abstract: Five compounds (I - V) were isolated from Potentilla chinensis Ser. On the basis of spectral data and chemical evidence. I - V were identified as 2alpha-hydroxyoleanolic acid (I), 2alpha-hydroxyursolic acid (II), 5, 7, 4'-trihydroxyflavone (IIl), beta-sitosterol (IV), daucostarine (V). All these compounds were isolated from Potentilla chinensis Ser for the first time.
