摘要： Dali tea (DLT) made by wild tea plant (Camellia taliensis) has been very popular in the market.However, the signature compounds and health benefits of DLT were not reported yet. To comprehensively understand metabolite signatures and potential health-function, the distinct metabolite signatures and hypoadiposity effect between DLT and Yunkang tea (YKT, made by Camellia sinensis var assamica cv. Yunkang 10) were comparative investigated. Our data found that catechins, and dimeric catechins were lower in DLT than YKT. In contrast, the levels of phenolic acid and amino acids were higher in DLT than YKT. An un-targeted metabolomics and a chemometric analysis indicated that flavonoid biosynthesis is a major pathway that distinguishes DLT from YKT. Additionally, chlorogenic acid, ellagic acid, arginine, tyrosine, and theanine were identified as characteristic metabolites of DLT. Furthermore, animal experiment showed that YKT performs better efficiency than DLT on alleviating hyperadiposity and renal damages in high-fat-diet induced obese mice.
