Three novel prenylated xanthones, 1-3, have been isolated from the root bark of Carcinragerrardii HARVEY ex T. R. SIM (G. natalensis SCHLECHTEK; G. transuaalensis BUKTT DAVY; Guttiferae). Structure elucidation was achieved by a combination of one-and two-dimensional NMR spectroscopic techniques, inc
