Abstract:
Total phenolic and flavonoid contents in various extracts of Salvia aristata (Labiateae) were evaluated by colorimetric methods and the best results were found for 50% hydro methanol extract with total phenolic (51.25±0.035mg/L) and flavonoid contents (10.95±0.004 mg/L). The extracts were also subjected to screening for their possible antioxidant activity by using 2, 2-diphenyl-1-picrylhydrazyl (DPPH) assay and the free radical scavenging activity of 50% hydro methanol extract was better than the other extracts (IC50=3.4 mg/mL). Significant correlation was found between radical scavenging activity and total phenolic and flavonoid contents of the extracts.
