[Objective] To analyse the constituents of Viscum ovalifolium DC. [Methods] The chemical constituents of Viscum ovalifolium DC were isolated by silica gel column chromatography, purified by crystallization and identified by spectroscopy method. [Results] Lupeol acetate, ?-amyrin and oleanolic acid were isolated and identified. [Conclusion] Lupeol acetate, ?-amyrin and oleanolic acid are isolated from Viscum ovalifolium DC for the first time.
