- Abstract
Extracts of nine plants were studied for DPPH radical scavenging and reducing abilities. Pentatropis spiralis, Calotropis procera, Helitropium curassavicum, Withania somnifera and Chenopodium album showed reducing power ranging from 34% to 146%. Suaeda fruticosa, Trianthema portulacastrum, Pluchea lanceolata and Rumex dentatus has excellent antioxidant potential proved by their DPPH scavenging and reducing power. 1000µg/10µl chloroform extract of S. fruticosa gave 92% scavenging with IC50 value less than 0.7µg/10µl while its hexane extract possessed 80% reducing activity at 100µg/10µl concentration. DPPH free radical scavenging by methanolic extract of Trianthema portulacastrum was 60% and 76% at 1000 and 100µg/10µl respectively with IC50 value of 0.03µg/10µl while the reducing activity of 124% at 100µg/10µl. Methanolic extract of P. lanceolata showed 91% and 70% scavenging activity at 1000 and 100µg/10µl with IC50 value of 0.7µg/ 10µl. Reducing power is comparable with the reference BHA standard that is 98% at 100µg/10µl concentration. Rumex dentatus' extracts are excellent DPPH scavengers and hydrogen donators produced 156% reduction. Chloroform extract was inefficient antioxidant. These results make these plants a candidate for future research for treating ailments due to imbalance in free radicals.
