Abstract

In our systematical investigation on Chinese Meliaceae plants, the stems of Cipadessa baccifera collected in Yunnan province were studied. Two new tetranortriterpenoids, cipadessalide ( 1) and rubralin D ( 2), one new pregnane, 3beta,4beta-dihydroxy-2beta-acetoxypregnan-16-one ( 3), and two new sesquiterpenoids, bacciferins A ( 4) and B ( 5), along with 10 known compounds were isolated. Their structures were elucidated by 1D and 2D NMR spectra and other spectroscopic studies, as well as chemical conversion.
