英文摘要：

Polyphenols of fruit tree was one of the important secondary metabolic substances and exist widely in fruit trees and fruit organs. It made the plant could prevent low temperature, diseases and pests. There were some regulatory effects on the growth, development and adaptability of fruit trees dependent the effect, and which play an important part in various fields such as food, medical, feed and environmental protection in future because of their unique physiological and biochemical properties. As a pure natural product which was renewable, the polyphenols form fruit tree would be playing the tremendous role in future in our cyclic type economic structure. The relations of this material would be closer to the people＇s production and the life, and the prospect of application would be broader. Present situation and trend are as follow： （1） the relations of structure and the performance of polyphenol, （2） Study of derivatization reaction of fruit tree polyphenol and （3） the deepened in the healthcare mechanism aspect research and so on. The study and application of physiological and biochemical function of polyphenols of fruit tree were summarized in the article, which can provide corresponding reference to development and utilization polyphenols of fruit tree further.
