摘要
目的建立知母中总黄酮提取工艺,为知母总黄酮开发和利用提供依据。方法对提取方法、提取溶剂、提取时间进行研究,采用紫外分光光度法测定知母中总黄酮含量。结果知母中总黄酮较佳提取工艺为:70%乙醇超声提取30min。结论该方法简便、快速、准确,可作为知母中总黄酮提取及含量测定方法。
Objective To estable a method of extraction technology of total flavonoids to offer a basis for Anemarrhena's development. Methods It was studied on method, solvent, time of extraction of Anemarrhena's tatol flavonoids and was determined tatol flavonoids'content of Anemarrhena by UV - spectrophotometry. Results It was best extraction technology of Ultrasonic Extraction total flavanoids for 30min by 70% acohol. Conclusion This method was simple, quick, and accurated, and suitable to extract and determine total flavonoids' content of Anemarrhena.
