Antioxidant Activity of Saraca Indica (Roxb.) De. Wilde Methanolic Leaf Extract

Abstract

India is home to one of the most significant indigenous medicinal herb called Saraca asoka, an IUCN (International Union for Conservation of Nature) red listed tree species. The goal of the current study was to assess the antioxidant capacity of Saraca indica leaf extract. The findings indicated that certain active phytochemicals with antioxidant properties were present in the extracts. The maximum percentage for scavenging the DPPH radical was 60.50% at a concentration of 0.0825 mg/ml. The methanolic extract of Ashoka leaf has an IC50-DPPH value of 0.064 mg/ml.

The total flavonoid value was found to be 2.41±0.004 mg of quercetin equivalent per gram of flavonoid in the dry extract sample, and the total tannin value was found to be 4.16±0.003 mg per gram in the dry extract sample. The FRAP value of the methanolic leaf extract was found to be 25.2±0.004 mg ferrous sulphate hexahydrate equivalent per gram of dry weight. The methanolic leaf extract of Saraca indica at a concentration of 0.2 mg/ml has an absorbance value of 0.332±0.004 for the reduction power assay.
