Eight compounds were isolated from the ethyl-acetate extract of the stem of Mallotus apelta Muell. -Arg. The structures of eight compounds were identified by means of spectroscopic analysis as 12-ursen-3-one (I), 3-hydroxy-12-ursen (II), mussaenoside (III), 6-methoxy-2H-1-benzopyron4-one (IV), ursolic acid (V), acetyl aleuritolic acid (VI), beta-sitosterol-3-O-beta-D-glucopyranoside (daucosterol VII), beta-sitosterol (VII). Compound I to approximately V were obtained from this plant for the first time.
