摘要
From the methanolic extract of the roots of Clerodendrum philipinum, a new rearranged abietane diterpene (1) and eight known compounds were isolated by various chromatography methods. Their structures were identified by means of spectroscopic methods, including 1D- and 2D-NMR, as 17(15-->16),18(4-->3)-bisabeo-11,12,14,16-tetrahydroxy-3,5,8,11,13,15-abietahexaen-7-one (1), binankadsurin A, clerodenoside A, martynoside, acteoside, isoacteoside, astragalin, p3-sitosterol, and daucosterol. Binankadsurin A was found for the first time from a Clerodendrum species.
