temperature for 1 h. The blank was prepared by replacing the oleoresin
with 1 ml of methanol. The absorbance was measured at
517 nm against methanol. The scavenging activity was expressed
as the % inhibition and calculated by using the following formula,2 h of incubation at room temperature, the absorbance was measured
at 765 nm. Gallic acid (0–500 mg/L) was used for calibration
of standard curve. The results are expressed as gallic acid equivalents
(GAEs) in mg/g of resin.
