title: Two octanordammarane triterpenes from Commiphora kua.
abstract: The resin of Commiphora kwo yielded two new octanordammarane triterpenes namely 15 alpha-hydroxymansumbinone and 28-acetoxy-15 alpha-hydroxymansumbinone, along with the four known compounds, mansumbinone, mansumbinol, (16S, 20R)-dihydroxydammar-24-en-3-one and T-cadinol. These structures were elucidated by spectroscopic techniques, including 1D and 2D NMR spectroscopy, and X-ray analysis.
