The reaction mixture consisted of 0.2 ml of the diluted extract, 4.8 ml of distilled
water, and 0.5 ml of the Folin-Ciocalteu reagent. After 3 min, 1 ml of saturated sodium carbonate solution was added and the mixture was made
up to 10 ml with distilled water. The mixture was thoroughly mixed, allowed to stand for 1 h in the dark at the room temperature, and the absorbance
was measured at 765 nm (Jenway 6505 UV-Visspectrophotometer, 160A; Keison, Essex, England). Total phenolic content was expressed as mg gallic
acid equivalents (GAE) per 100 g of the dried
spearmint (d.s.)
