Abstract Activity-directed fractionation of the ethanolic extract of Psorospermumfebrifugum has led to the isolation and structural elucidation of eight new dihydrofuranoxanthones. Six compounds were found to exhibit significant in vitro cytotoxic activity against 9PS cells in culture. A new dihydrofuranoxanthone epoxide, related to psorospermin exhibited activity both in vitro and in vivo .
