Abstract: An efficient microwave –assisted extraction (MAE) technique was developed to extract total phenolics content (TPC) from Yellow bell flowers. The optimal extraction conditions were as follows: methanol concentration 50%v/v; temperature, 60 °C; extraction time, 2 min. At this condition, maximum TPC (0.610 mg gallic acid equivalents/g dry). The condition that maximum total phenolic content was the same as the conditions that maximum antioxidant activity DPPH (0.361 mg TE equivalents/g dry).
