dichapetalum barteri/neoplasms

Two new bisbibenzyls, heudelotol A (1) and B (2), along with the known bibenzyls, (E)-combretastatin A-1 (3) and combretastatin B-1 (4) have been isolated from the ethyl acetate extract of the roots of Dichapetalum heudelotii. Structure elucidation of all four isolated compounds was achieved using

Fractionation of an ethyl acetate-soluble extract of the stem bark of Dichapetalum gelonioides, collected in the Philippines, using the LNCaP (hormone-dependent human prostate) cell line as a monitor, led to the purification of three dichapetalin-type triterpenoids [dichapetalins A (1), I (2), and J

Six dichapetalins named dichapetalins N-S were isolated from Dichapetalum mombuttense, Dichapetalum zenkeri and Dichapetalum leucosia. They were accompanied in the same plants by the known dichapetalins A, B, C, I, L and M. The structures of the compounds were elucidated by 1D and 2D NMR experiments
