Two New Diterpenoids from Plectranthus nummularius BRIQ.

Abstract

Two new antioxidative diterpenoids, plectranthol A (3)[19-O-(3, 4-dihydroxybenzoyl)-11, 12-dihydroxy-20(10→5)-abeo-abieta-1(10), 6, 8, 11, 13-tetraene] and plectranthol B (4)[12-O-(3-methyl-2-butenoyl)-19-O-(3, 4-dihydroxybenzoyl)-11-hydroxyabieta-8, 11, 13-triene] along with two known diterpenoids, parvifloron E (1) and F (2) were isolated from the leaves of Plectranthus nummularius BRIQ. Antioxidative activities of the compounds were measured by the α, α-diphenyi-β-picrylhydrazyl (DPPH) method.
