“药食同源”植物葛根中总黄酮提取方法的研究进展

Research progress on extraction of total flavonoids from Puerariae Radix

葛根是一种药食同源类植物,在中药和食品工业中有着广泛应用。药食同源体现了食物的药用功能,药食同源植物兼具了食物丰富的营养价值和中药的药用价值。葛根黄酮是葛根的主要活性成分。本文主要综述了葛根总黄酮的提取方法,重点介绍了浸提法、超声辅助提取法、微波辅助提取法、超声波预处理微波萃取法、超临界流体萃取法、微生物酶解破壁法等提取方法,并对提取葛根总黄酮的发展作出了展望,以期对葛根的生产提供理论参考和指导。

Puerariae Radix is a kind of ＂homology of medicine and food＂ plant, which is widely used in traditional Chinese medicine and food industry. Homology of medicine and food means that some foods and medicines are derived from the same source. Medicinal and edible traditional Chinese herbs have both nutritional and medicinal value. In this paper, the extraction methods of total flavonoids from Puerariae Radix were reviewed. The extraction methods such as soaking extraction, ultrasonic assisted extraction, microwave assisted extraction, ultrasonic pretreatment and microwave extraction, supercritical fluid extraction, and microbial enzymatic extraction were introduced. The development of extraction of total flavonoids from Puerariae Radix was prospected. The paper can give theoretical reference and guidance for the production of Puerariae Radix.
