目的:探究超声波法和普通回流法提取广西益母草中总碱的效益。方法:超声波法和普通回流法。结果:在提取益母草总碱时,超声波提取法较回流提取法有省时、节能、提出率高等优点。结论:用超声波法提取益母草中的总碱优于用普通回流法,超声波法提取益母草总碱的最佳条件为超声波频率为80 kHz,超声处理40 min,以75%乙醇为溶剂。 Objective: To explore the ultrasonic method and the ordinary reflux method to extract total alkaloids from Guangxi Motherwort benefit. Methods: Ultrasonic method and ordinary reflux method. Results: When extracting total alkaloids from Leonurus, ultrasonic extraction has the advantages of saving time, saving energy and presenting higher rates than reflux extraction. CONCLUSION: Ultrasound extraction of total alkaloids from motherwort is better than that of common refluxing method. The optimal conditions of extraction of total alkaloids from motherwort by ultrasonic method are ultrasonic frequency 80 kHz, sonication 40 min and 75% ethanol as solvent.
