The seeds of Otoba paruifolia contain three novel compounds apparently derived from homogentisic acid, rel-(1'R,5'R)-2-(1'-farnesyl-5'-hydroxy-2'-oxocyclohex-3'-en-1'-yl)-acetic acid and its acetate as well as rel- (1'R,4'S,5'R)-2-(1'-farnesyl-4',5'-dihydroxy-2'-oxocyclohexan-1'-yl)-acetic acid δ-lactone. The structure of an additional isolate, previously described as 2-(1'-farnesyl-2'-hydroxy-5-oxocyclohex-3'-en-1'-yl)-acetic acid γ-lactone was revised to rel-(1'R,5'R)-2-(1'-farnesyl-5-hydroxy-2'-oxocyclohex-3'-en-1'-yl)-acetic acid δ-lactone.
