[Study on the chemical constituents of Viscum ovalifolium].

OBJECTIVE: To study the chemical constituents of Viscum ovalifolium. METHODS: The chemical constituents from Viscum ovalifolium were isolated and purified by silica gel column chromatography, polyamide column chromatography and recrystallization methods. Their structures were elucidated by physicochemical properties and spectral analysis. RESULTS: Twelve compounds were isolated and their structures were identified as 1-octadecene (1), ethyl palmitate (2), 28-hydrxy-amyrone (3), betulinic acid (4), rutin (5), quercetin (6), beta-amyrinpalmitate (7), lupeol acetate (8), beta-amyrin (9), beta-sitosterol (10), lupeol (11) and oleanolic acid (12). CONCLUSION: Compounds 1 - 6 are obtained from this plant for the first time.
