Abstract:

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%.

Key words: lotus leaves, alkaloids, ultrasonic-assisted method, extraction technology
