核桃果实多酚活性及其分离纯化研究进展

核桃多酚类化合物主要为酚酸和单宁类,以及少量的黄酮类,是核桃果实重要的化学组成成分。在生产中,核桃多酚往往随加工副产物被废弃,造成资源浪费。核桃多酚具有多种生物活性,且果实不同部位多酚的种类和含量差别较大。本文从核桃果实多酚的种类、含量、生物活性及分离纯化等方面进行概述,以期为核桃多酚的产业化制备提供理论依据。

Research Progress on Polyphenol Activity and Separation and Purification of Walnut Fruit

Walnut(Juglans regia L.)polyphenols mainly include phenolic acids and tannins,as well as small amounts of flavonoids,which are important chemical components of walnut fruit. Polyphenols are discarded along with processing by-products in walnut production,resulting in resource waste. The phenols of walnut exhibit many bioactivities and varieties and their contents in different parts of the walnut fruit have large differences. The types,contents,biological activities,separation and purification of phenolic compounds in walnut fruits are summarized in this paper,which provides a theoretical basis for in industrialization of phenols.
