From the root of Rhamnella frangulioides(=Microrhamnus frangulioides), three compounds (Comp. I ; $mp;140{sim}142^{circ},;Comp.;II;;;mp;196^{circ},;Comp.;III;;;mp;136{sim}138^{circ})$ were isolated by silica gel column chromatographic purification which were identified as ${eta}-sitosterol$, chrysophanol, 1-methyl-2-carboxymethyl-3-methoxy-4,8-dihydroxy andthraquinone, respectively by spectral analysis.
