Fig. 2From: Natural products isolated from Tetragonula carbonaria cerumen modulate free radical-scavenging and 5-lipoxygenase activities in vitroAnalytical reversed-phase HPLC traces of a methanolic extract of T. carbonaria cerumen (2Â mg/mL), in the absence a and presence b of the free radical initiator, AAPH (80Â mg/mL). Peak intensities that decreased in the presence of AAPH (numbered arrows) indicate constituent compounds that scavenged AAPH-derived free radicals after 8Â hBack to article page
