Free Radical Scavenging Effect

The antioxidant capacity of apples peel extracts during the fruit development from three apple varieties (i.e., Ionathan, Golden Delicious and Starkrimson) were analyzed  at 7, 15, 35, 65, 107, 145 days after full bloom (DAFB). The total antioxidant capacities of extracts were evaluated using free radical scavenging effect over 1,1-diphenyl l-2-picrylhydrazyl (DPPH) radical,  being determined by a spectrophotometric method.The maximum antioxidant capacity was recorded in the apples harvested 7 DAFB.

Free Radical Scavenging Effect

This study was planned to assess the antioxidant and free radical scavenging effect of D-carvone against L-NAME (Nω-nitro-L-arginine methyl ester hydrochloride) induced hypertension. Hypertension was encouraged in adult male albino rats of the Wistar strain, considering 180–230 g, by oral administration of the L-NAME (40 mg/kg/ body weight/day) in drinking water for 4 weeks. Rats were cured with D-carvone (5, 10 and 20 mg/kg body weight) for four weeks. A significant reduction in the levels of non-enzymatic antioxidants such as vitamin C, vitamin E and reduced glutathione (GSH), in plasma were perceived in L-NAME induced hypertensive rats. Moreover, in vitro free radical scavenging activity of ABTS+ and DPPH• radical scavenging possible of D-carvone was also quantified. Treatment with D-carvone (5, 10 and 20 mg/kg bw) carries back all the above parameters to near usual level, in which 20 mg/kg displayed the highest effect than that of other two doses. Further, D-carvone displays concentration dependent antioxidant potential. These results suggest that D-carvone acts as an antioxidant and free radical scavenging agent against L-NAME induced hypertension.
