The influence of stress factors on a plant may lead to worse functioning of the plant and the loss of its crop. The effect of solani feeding on with regard to active compounds in the leaves was investigated in the study. The antioxidant activity of the leaves, the material on which the insects fed, was compared with that of the material that was not infested by the aphids. Stress level was evaluated on the basis of such physiological parameters as chlorophyll fluorescence and photosynthesis activity. An increase of 34.5% in the content of polyphenolic compounds, as compared to control, was demonstrated in the material exposed to the biotic stress caused by aphids. The content of phenolic acids was 28% higher while that of flavonoids rose by 25%. The increase in polyphenolic compounds augmented the antioxidant activity of the material.
胁迫因素对植物的影响可能导致植物功能变差及其作物减产。本研究调查了茄蚜取食对叶片中活性化合物的影响。将昆虫取食的叶片材料的抗氧化活性与未受蚜虫侵害的材料的抗氧化活性进行了比较。基于叶绿素荧光和光合作用活性等生理参数评估胁迫水平。与对照相比，遭受蚜虫引起的生物胁迫的材料中多酚类化合物含量增加了34.5%。酚酸含量高出28%，而黄酮类化合物含量上升了25%。多酚类化合物的增加增强了材料的抗氧化活性。
