Abstract

From the resinous exudate of Heliotropium sinuatum (family Boraginaceae), a new compound: 4-(3′,5′-dihydroxynonadecyl)phenol 1, together with eight previously described flavonoids, were isolated and their antioxidant activities were assessed by quenching measurements with ABTS and DPPH cation radicals.
