摘要：

Chemical investigation on the constituents of the cones of Cycas beddomei has resulted in the isolation of a new biflavonoid, 2,3-dihydro-4(m)-O-methyl amentoflavone, along with 2,3,2",3"-tetrahydro hinokiflavone, 2,3,2",3"-tetrahydro, amentoflavone, 2,3-dihydro amentoflavone. The last two compounds were not reported earlier from this plant. The structure of the new compound was established by detailed analysis of its spectral (mainly 1D and 2D NMR) data.
