非生物胁迫对发芽谷物多酚的影响研究进展

Research Progress on Effect of Abiotic Stress on Polyphenols of Sprouted Cereal

发芽能显著提高谷物还原糖、必需氨基酸、游离脂肪酸、膳食纤维及多酚类化合物的含量。非生物胁迫在一定程度上可以促进发芽谷物多酚类化合物的积累,同时提高发芽率,缩短发芽周期。本文考察了糙米、燕麦、荞麦、小麦、大麦等五种谷物发芽前后多酚种类的变化,同时介绍了谷物发芽时受到非生物胁迫(包括盐胁迫、超声波胁迫、光胁迫、等离子体胁迫及低氧胁迫)后多酚类化合物的变化,并简要阐述了非生物胁迫影响发芽谷物积累多酚类化合物的机理,旨在为谷物在逆境条件下发芽提供参考,以及为后续研究发芽谷物多酚提供可利用资源。

Germination can significantly increase the content of reducing sugars,essential amino acids,free fatty acids,dietary fiber and polyphenols of grain.Abiotic stress can promote the accumulation of polyphenols in sprouted cereal,increase the germination rate and shorten the germination cycle.In this paper,the changes of polyphenols before and after the germination of five kinds of grains,such as brown rice,oats,buckwheat,wheat and barley were examined,on the other hand the changes of polyphenols under abiotic stress(including salt stress,ultrasonic stress,light stress,plasma stress and hypoxia stress)during grain germination were introduced,and briefly expounded the abiotic stress affect the germinated grain accumulation mechanism of polyphenol compounds,aiming at providing reference for grain under the condition of adversity to sprout,and offering available resources for the following-up research on the germination of grain polyphenols.
