To investigate the correlation between the difference of secondary metabolites and the disease-resistance activity of different varieties of Congou black tea. Among a total of 657 secondary metabolites identified, 183 metabolites had anti-disease activity, 113 were key active ingredients in traditional Chinese medicine (TCM), 73.22% had multiple anti-disease activities, and all were mainly flavonoids and phenolic acids. The main enriched metabolic pathways were phenylpropanoid biosynthesis, biosynthesis of secondary metabolites, flavonoid biosynthesis, and metabolic pathways. Flavonoid and phenolic acid secondary metabolites were more correlated with anti-disease activity and key active TCM ingredients. Conclusion: The types of JGY and Q601 Congou black tea of the relative contents show large differences in secondary metabolites. Flavonoid and phenolic acid secondary metabolites were identified as the primary factors contributing to the variation in secondary metabolites among different varieties of Congou black tea. These compounds also exhibited a stronger correlation with disease resistance activity.
探究不同品种工夫红茶次生代谢产物差异与抗病活性之间的相关性。在总共鉴定出的657种次生代谢产物中，183种代谢产物具有抗病活性，113种是中药中的关键活性成分，73.22%具有多种抗病活性，且均主要为黄酮类和酚酸类。主要富集的代谢途径有苯丙烷生物合成、次生代谢产物生物合成、黄酮类生物合成以及代谢途径。黄酮类和酚酸类次生代谢产物与抗病活性及中药关键活性成分的相关性更强。结论：JGY和Q601品种工夫红茶次生代谢产物的种类及相对含量差异较大。黄酮类和酚酸类次生代谢产物被确定为导致不同品种工夫红茶次生代谢产物差异的主要因素。这些化合物与抗病活性也表现出更强的相关性。
