Two new prenylated benzoic acid derivatives, leptoic acid A and (+)-S-anodendroic acid (1-2), along with one known compound, 2,2-dimethyl-2H-1-benzopyran-6-carboxylic acid (3) were isolated from the stem of Euodia lepta (spreng.) Merr. Their structures were elucidated on the basis of the chemical and spectroscopic evidence.
