Abstract
Orthogonal experiment optimization of microwave-assisted extraction (MAE) conditions of total flavonoids from castor leaves with the factors of ethanol concentration, microwave power, extraction time, solid/liquid ratio on the yield of total flavonoids were studied. The results showed that optimum extracting conditions of total flavonoids from castor leaves were as follows: adding 1:50 g·mL-1 of 40% alcohol and extracting for 3 min,microwave irradiation power 464W. Microwave extraction of total flavonoids from castor leaves is fast, energy saving and high extraction rate.
