Abstract

Ultrasonic extraction of flavonoids in leaves of Hippophae rhamnoides Linn. (TFH) was optimized by an orthogonal experiment. The effects of ultrasonic treatment time, temperature, ratio of liquor to material and extraction times on the extraction yield of TFH were investigated. The optimized ultrasonic extraction was determined as follows: ratio of liquor to material 25mL/g at 46℃ for 25min with 85 % ethanol in a single ultrasonic extraction process. A comparison was conducted between ultrasonic and Soxhlet extraction. The extraction yield of TFH is 1.72 % by ultrasonic extraction, which is almost the same as by Soxhlet extraction. Ultrasonic extraction is faster and needs less solvent, which are superior to Soxhlet extraction. Mathematical simulation values based on ultrasonic extraction are consistent with experimental values.
