Research Progress in Extraction,Physiological Function of Lotus Seedpod Procyanidins and Their Application in Food Industry

Lotus seedpod is the mature receptacle of lotus,which is an important part of lotus. It is often used as a blood stasis and hemostatic medicine in the folk. There were lots of procyanidins in the lotus seedpod,which can be used as one of the important raw material of procyanidins extraction,and are expected to replace the crops,such as grape seed,raspberry seed,and so on. And then the waste lotus seedpod will eventually be maximized used,which can reduce the costs of procyanidins production finally. In this paper,the methods of extracting procyanidins from lotus seedpod in recent years are summarized and their advantages and disadvantages are also analyzed. In addition,the main physiological functions of procyanidins in lotus seedpod are introduced by many examples. Finally,the application of procyanidins in food industry is introduced too. The results of this study provide some theoretical basis for the further study of procyanidins in the lotus seedpod and the rational development and utilization of the lotus seedpod.
