Evaluation of Radical Scavenging Activity of Ethnomedicinal Syrup “Nitya Yevvana Kashayam”

Abstract

This study aimed to evaluate the antioxidant compounds and their free radical scavenging capacity from Crude aqueous extract of ethnomedicated syrup “ Nitya Yevvana Kashayam (NYK)”. Estimation of antioxidant activity compounds viz ., Total Phenolic Content (TPC), Total Flavonoids (TF) and Flavonol content (T.fl) were optimized by calorimetric methods respectively. DPPH and ABTS scavenging assay were used for the determination of free radical scavenging potentiality. Results reported that TPC (272.30 ± 0.44 mg GAE/gm DW), TF (158.65 ±0.82 mg QCE/gm DW) and the radical scavenging activity measurement, done with DPPH assay (EC 50 = 22.24 ± 0.18 µg/mL) and ABTS assay (EC 50 = 18.64 ± 1.35 µg/mL), present in NYK proved to be a good source of natural antiradical scavenger and therefore, recommended for utilization as potent medicine supporting the traditional ethnic claim.
