【Abstract】 Four compounds were isolated from Viscum coloratum （Kom.）Nakai by means of both solvent extraction and chro- matographic separation methods.These constituents were identified through spectral analysis of IR,¹H-NMR,¹³C-NMR and MS.They are syringin,oleanolic acid,β-acetylamyrin and homoeriodictyol-7-β-D-glucoside.It is the first separation from freshly col- lected Viscum colortum （Kom.） Nakai,which parasitizing on pear tree.更多还原
