Objective: To optimize microwave-assisted extraction process conditions of total alkaloids from Lycopodii Herba. Method: Acid dye colorimetry was employed to determine the content of total alkaloids with lycodoline as index component.Based on single factor tests
effects of liquid-solid ratio
extraction temperature and time on yield of total alkaloids were investigated with a three-factor and three-level Box-Behnken central composite design
microwave-assisted extraction conditions of total alkaloids from Lycopodii Herba was optimized by response surface methodology and compared with traditional extraction technique. Result: Optimum conditions were as follows:extracted 8 min with 17 times the amount of methanol-water-hydrochloric acid (85:15:1) at 72℃;yield of total alkaloids was 4.092 mg·g-1 under these conditions
which was consistent with the theoretic value of 4.070 mg·g-1. Conclusion: Microwave-assisted extraction process has many advantages over conventional methods
such as time saving
high extraction ratio and low solvent consumption.
