Otholobium glandulosum (L.) J.W. Grimes (= Psoralea glandulosa L.) (Fabaceae) is a resinous bush that grows in Chile. The chemical composition of its resinous exudate was determined for the first time. Three meroterpenic: bakuchiol (8), 3-hydroxybakuchiol (11), 12-hydroxyisobakuchiol (12) and a new compound kuchiol (13) were isolated and their structures were determined. The antioxidant activity of the terpenic compounds and resin was evaluated using the bleaching of DPPH radical, Ferric Reducing Antioxidant Power (FRAP) and Total Reactive Antioxidant Properties (TRAP) assays.
