Abstract： The growing environment significantly influences the accumulation of chemical compounds in tea plants. However，systematic studies onthe changes in chemical compositionafter translocating thetea cultivar “Huangshanzhong'to the high-latitude Shandong region remain scarce.This study investigated the green tea samples of Camella sinensis cv.Huangshanzhong from tworegions： the native origin （YCD，Huangshan，Anhui） and a transplanted region （SD，Rizhao， Shandong）. Differences in thecontent levels of the chemical components were analyzed.Additionaly，widely-targetedmetabolomicstechniques wereemployed toidentifydierentialmetabolites andelucidate core metabolic pathways.The results demonstrate that SD samples exhibited significantly higher levels of water-soluble carbohydrates，total ash， water-soluble ash，water extract content and total gallylated catechins than YCD.While the total polyphenols and caffeine showed no inter-regional diference.SD accumulated more asparagine， glutamate，and arginine， whereas YCD was richer in flavor-related amino acids，such as theanine， GABA， lysine.Metabolomicsanalysis identified116 diferential metabolites （73upregulated，43 downregulated），with flavonoids exhibitingthe highest abundance and diversity among them.KEGG enrichment analysis further revealed thatthe purine metabolism，phenylalanine metabolism，and pyrimidine metabolism pathways were the most significantly enriched pathways，contributing most to the diferences between the SD and YCD samples.This study provideda systematiccomparison of chemical components in green tea from cv.‘Huangshanzhong’after high-latitude transplantation versus the original cultivation，offering scientific insights into tea cultivar adaptation and flavor quality optimization.

‘黄山群体种’（Camelliasinensiscv.Huangshanzhong）原产于安徽省黄山附近地区[1]，是黄山毛峰、松萝茶等历史名茶的核心原料，更是安徽本地的优势茶树品种。（剩余22145字）
