Tóm tắt

Prunella vulgaris L. (PV) have been reported to have a variety of important biological activities. A process for rosmarinic acid (RA) extraction - antioxidants from PV was performed to obtain the highest extraction yield, strongest antioxidant activity and optimized by a multi-response optimization process. A three-level three-factor Box- Behnken design (BBD) was performed as response surface methodology (RSM) with desirability function (D) to attain the optimal extraction parameters. The rosmarinic acid extraction rate was determined by UV-Vis method with linear line Y = 2.1033x + 0.1108, R2 = 0.9966. The DPPH


and ABTS●+ scavenging percentage was used to represent the antioxidant ability. The maximum D value of 0.251, along with the maximum yield (6.025%), %RA (0.115%), scavenging percentage DPPH (IC50) (84.975 µg/ml) and ABTS


(TEAC) (0.207) were achieved after an ethanol


concentration of 60o, an extraction time of 60 min, using an extraction temperature of 50°C.
