摘要：

A new flavonoid glycoside, identified as rhamnazin-3-O-beta-D-(6 ''-beta-hydroxy-beta-methylglutaryl)-beta-D-glucoside-4'-O-beta-D-glucoside (1), along with four known compounds, shikimic acid (2), quebrachitol (3), abscisic acid (4), 3,5-dihydroxy-1,7-bis(4-hydroxyphenyl)heptane (5), were isolated from the branches and leaves of Viscum coloraturn. Their structures were elucidated on the basis of MS, 1D NMR, and 2D NMR techniques. All compounds were isolated in the family Loranthaceae for the first time. This paper describes the isolation, structural elucidation as well as in vitro antioxidant activity of these isolates.
