Studies on the Components of Clerodendron trichotomum THUNB. III. A New Glycoside, Acacetin-7-glucurono-(1→2)-glucuronide from the Leaves

A new glycoside (I) was isolated from the leaves of Clerodendron trichotomum THUNB. and confirmed to be acacetin-7-β-D-glucurono-(1→2)-β-D-glucuronide, the sugar part of which was the same as that of glycyrrhizin in licorice.
