Four flavonoids (1-4), a phenylethyl glycoside (5), and a phenylpropanoid glycoside (6) were
isolated from the flowers of Buddleia officinalis (Loganiaceae). Their structures were determined
by chemical and spectral analysis. Among the isolated compounds, luteolin (1) and
acteoside (6) exhibited the most potent antioxidative activity on the NBT superoxide scavenging
assay. In addition, compounds 1-6 revealed weak antifungal activity, and no hemolytic
activity.
