OBJECTIVE To study the chemical constituents of Viburnum erosum var. erosum and Viburnum odoratissimum var. awabuki.METHODS Compounds were isolated by various column chromatographies and identified by a combination of spectrophotometric METHODS. RESULTS Eight(No. 1-8) and 5(No. 2, 4, 9-11) compounds were isolated from the stems and leaves of V. erosum var. erosum and V. odoratissimum var. awabuki, respectively. The compounds are identified as follows: β-sitosterol(1), ursolic acid(2), blumeatin(3), daucosterol(4),(-)-lyoniresinol 3α-O-β-D-glucopyranoside(5),(+)-lyoniresinol 3α-O-β-D-glucopyranoside(6), adoxoside(7), loganin(8), a-amyrin(9), 6α-hydroxylup-20(29)-en-3-on-28-oic acid(10), 2a-hydroxyursolic acid(11). CONCLUSION Compounds 3, 5, 7, 8 are isolated for the first time from the genus Viburnum. Six(No. 2-5, 7, 8) and 3(No. 4, 9, 11) compounds are isolated from the stems and leaves of V. erosum var. erosum and V. odoratissimum var. awabuki for the first time, respectively.
