Abstract

A new method of microwave assisted extraction (MAE) was used to extract antioxidant compounds from Plantago major L. Ultrasound-assisted extraction (UAE) and kinetic maceration were studied as comparison process. The effect of part of plant, duration and temperature on the free radical scavenger activity, total phenol and flavonoid content of the extract were determined. MAE was found to be the most effective method capable of yielding 1.72 %GAE total phenol, 1.94 %CE total flavonoid and giving EC50 equivalent to 474.11 ppm of crude drug with 700C and 20 min of extraction temperature and time, respectively. The percent recovery of antioxidant compounds was found to increase with increasing MAE time and temperature. It was also found that antioxidant compounds of the leaf was much greater than that of root and petiole.
