In plants, flavonoids play an important role in biological processes. They are involved in UV-scavenging, fertility and disease resistance. Therefore, in this study, we attempted to quantify and characterize phenolic compounds in Aesculus parviflora Walt. leaves and Aesculus glabra leaves partly suffering from attack by a leaf mining insect (C. ohridella). A total of 28 phenolic compounds belonging to the hydroxycinnamic acid, flavan-3-ols and flavonol groups were identified and quantified in Aesculus parviflora and A. glabra leaf extracts. Significantly decreased concentrations of some phenolic compounds, especially of flavan-3-ols, were observed in infected leaves compared to the non-infected ones. Additionally, a higher content of polymeric procyanidins in leaves of Aesculus parviflora than in Aesculus glabra may explain their greater resistance to C. ohridella insects.
在植物中，类黄酮在生物过程中发挥着重要作用。它们参与紫外线清除、生育能力和抗病性。因此，在本研究中，我们试图对小花七叶树（Aesculus parviflora Walt.）叶片和部分遭受潜叶昆虫（C. ohridella）侵害的光滑七叶树（Aesculus glabra）叶片中的酚类化合物进行定量和表征。在小花七叶树和光滑七叶树的叶片提取物中，共鉴定并定量了28种属于羟基肉桂酸、黄烷 - 3 - 醇和黄酮醇类的酚类化合物。与未感染叶片相比，在感染叶片中观察到一些酚类化合物的浓度显著降低，尤其是黄烷 - 3 - 醇。此外，小花七叶树叶片中聚合原花青素的含量高于光滑七叶树，这可能解释了它们对C. ohridella昆虫具有更强抗性的原因。
