苜蓿皂甙的研究应用进展

苜蓿Medicago sativa作为高产、廉价、优质的蛋白质饲草，发挥着越来越重要的作用，苜蓿中含有皂甙、叶蛋白、黄酮类、多糖、天然色素、膳食纤维等多种生物活性成分,具有很高的饲用价值和药用价值。苜蓿皂甙是苜蓿生物活性的物质之一，具有降低胆固醇、调节脂质代谢、增强机体免疫、抗氧化等功能，对畜禽的生长性能有促进作用。对苜蓿皂甙的结构、理化特性、生物学功能以及苜蓿皂甙提取工艺进行了简单的介绍，并论述了近几年来苜蓿皂甙在动物生产中的应用，最后探讨分析了苜蓿皂甙发展存在的问题和发展前景。

Research and application progress on alfalfa saponin

As one of high quality legumes,alfalfa is becoming more and more important.Alfalfa contains many biological active components,which also have medicinal value and feeding value,such as saponin,leaf protein,flavonoid,polysaccharide,natural pigment and dietary fiber.In which,alfalfa saponin,with the functions of reducing cholesterol level,antioxidization,immune improvement,could enhance the growth performance of livestock and poultry.The structure,physical and chemical characters,biological functions,extraction techniques of alfalfa saponin and its application in animal production were discussed,and the current situation and development prospect were analyzed as well.
