莲房原花青素提取方法、生理功能及其在食品工业中应用的研究进展

莲房是莲科植物莲的成熟花托，是莲的重要组成部分，在民间常被作为一种化瘀止血药使用。研究发现莲房中存在含量较多的原花青素，可作为原花青素提取的重要原料来源，有望替代葡萄籽、树莓籽等作物提取原花青素，以此能够将莲房变废为宝，降低原花青素生产成本，最终实现莲房资源的最大化利用。本文针对性地归纳了近年来有关莲房中原花青素提取工艺方法，分析了各方法的优缺点；以实例方式介绍了莲房中原花青素的主要生理功能；最后根据功能简要介绍了莲房中原花青素在食品工业中应用情况。本文研究结果将对莲房中原花青素的深入研究和莲房资源的最大化合理开发利用提供一定的理论依据。

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.
