Abstract :
Salacia is a valuable medicinal genus found to be composed of various secondary metabolites. Hence, the present study was aimed to estimate three important secondary metabolites such as phenol, flavonoid and tannin. Antioxidant assays such as DPPH assay and ABTS assay and Total Antioxidant Capacity were also studied for this medicinal genus. Seven species of Salacia were considered for this present study. They are Salacia beddomei Gamble, Salacia chinensis L, Salacia fruticosa Heyne ex Lawson, Salacia gambleana Whiting & Kaul, Salacia macrosperma Wight, Salacia malabarica Gamble, and Salacia oblonga Wall. Various concentrations such as 20µg, 40µg, 60 µg, 80 µg and 100 µg were taken for all studies and the values are entered in terms of Mean±SD. In case of DPPH assay and ABTS assay, IC50 values are calculated using ANNOVA and Total Antioxidant Capacity was calculated using a calibration curve.
