Abstract
4'-Demethyldeoxypodophyllotoxin was isolated as the sole cytotoxic constituent of a chloroform-soluble extract of the stem bark of AMANOA OBLONGIFOLIA. Also identified from this extract were a number of noncytotoxic isolates that comprised the lignans, (+)-sesamin and paulownin, the triterpenes, friedelin, canophyllol, betulin, betulinic acid, and ursolic acid, and the sterols, beta-sitosterol and daucosterol.
