Ultrasonic-assisted Extraction of Alkaloids from Lotus Leaves

LIU Shu-xing1,GUO Rui-xia2,ZHAO Fang1(1.Life College of Science and Technology,Shaanxi University of Science and Technology,Xi'an 710021,China ;2.Jiaozuo Teachers College,Jiaozuo 454002,China)  
Ultrasonic-assisted extraction was applied to prepare alkaloids from lotus leaves.The extraction conditions of alkaloids were optimized to maximize the yield of alkaloids by single-factor and orthogonal array methods.Under the optimized extraction conditions as follows:extraction for 0.5 h with 65% ethanol as the extraction solvent and the solid to liquid ratio of 1:50,at 45 kHz,80 ℃ and pH 5,the yield of alkaloids reached 0.17%.
