油茶多酚的提取及功能研究进展

摘要

Polyphenolsis themostimportantandwidely distributed secondarymetabolitesin Camellia oleifera. It not only promotesquality,luster,lfavorand stressresistance ofC. oleifera, butalso possesses excellent biologicalfunctions, suchasantioxidantactivity,antibacterialactivity, scavengingfreeradical,anti-tumor,anticoagulation,antithrombotic activity, hypoglycemicactionandinhibitingfattyacid synthase. In order tofurther understand chemicalmechanismsand potential usevalue of polyphenolsin C. oleifera,and to offerareferenceforresearching polyphenolsinC. oleifera, this paperreviewed the statusandadvanceinresearch on extraction,ingredientanalysis,functionresearchandmolecular structuremodiifcation of polyphenolsin C. oleifera.%油茶多酚是油茶中最重要且分布最广泛的次生代谢物质之一,不仅对油茶的品质、色泽、风味和抗逆性有一定的影响,而且具有天然的抗氧化活性、抑菌、清除自由基、抗肿瘤、抗凝血、抗血栓、降血糖及对脂肪酸合酶的抑制作用等功能.为了进一步了解油茶多酚的化学本质及其潜在的利用价值,从而为油茶多酚的研究提供参考依据,文中综述了油茶多酚的提取、成分分析、功能研究和分子结构改造等方面的研究情况和研究进展.
