✦ Synopsis

Two new furanoid diterpener, malabarolide Br (1) and menispermacide, have been isolated from the stems of Tinoeponr makabarica. Their structures were established by single crystal X-ray diffraction. The structure of menispermacide (2) was revised on the basis of single crystal X-ray diffraction analysis. Menispermacide provider the only known example of the occurrence of disulfide bearing diterpene from higher plants.
