Extract of Ginkgo biloba:Biological Functions and Applications in Poultry Breeding

银杏叶提取物(extract of Ginkgo biloba,EGb)含有萜类内酯、黄酮类和聚异戊烯醇类化合物等活性成分。其中,黄酮类化合物具有抗氧化、清除自由基等作用,而萜类化合物作为强效血小板活化因子(plateletactivating factor,PAF)拮抗剂,可发挥改善心脑血管循环、降血脂、保护肝脏等生物学功能。为此,EGb已成为多种学科领域的研究热点之一。本文主要就EGb主要生物学功能及其在家禽养殖中的应用进行概述。

Extract of Ginkgo biloba(EGb) contains active constituents including terpene lactones,flavonoids and poly isoamyl enol compounds,and so on.Among them,flavonoids have antioxidant activity and the ability to scavenge free radicals,and terpene compounds served as antagonists against potent platelet activating factor(plateletactivating factor,PAF) have biological functions such as improving cardiovascular circulation,lowering blood fat,and protecting the liver.Therefore,EGb has become a hot pot in multi-disciplinary research areas.Main functions of EGb and its applications in poultry breeding are reviewed in this article.
