Lantana camara L., Family Verbenaceae commonly known as wild or red sage, is the most widespread species of this genus, growing luxuriantly in tropical, sub-tropical and temperate regions [1]. L. camara is used in folk medicine as vulnerary, diaphoretic, carminative, antiseptic, antispasmodic and tonic and [2–3]. A phytochemical investigation of the aqueous-methanolic extract of its flowers had led to isolation of a new flavonoidal compound, apigenin 7-O-β-D-galacturonopyranosyl-(2→1)-O-β-D-galacturonopyranoside with the eleven flavonoids, luteolin 7-O-β-D-glucuronopyranosyl-(2→1)-O-β-D-glucuronopyranoside, apigenin 7-O-β-D-glucuronopyranosyl-(2→1)-O-β-D-glucuronopyranoside, vitexin, isovitexin, apigenin 7-O-β-D-galacturonopyranoside, luteolin 7-O-β-D-glucopyranoside, luteolin 7-O-β-D-galactopyranoside, luteolin 4'-O-β-D-glucopyranoside, apigenin 7-O-β-D-glucopyranoside, luteolin and apigenin. The aqueous methanolic of L. camara flowers and some compounds proved a significant antioxidant effect.
