摘要： Different tea cultivars possess various manufacturing suitibilities. However, its underlying relationship with lipids remains unexplored. Herein, 22 Chinese tea cultivars suitable for green, black, oolong and white tea manufacturing were analyzed by comparative lipidomics using UHPLC-Q-Exactive/MS. A total of 430 lipids were detected and 84 key differential molecules were screened. The green tea cultivars showed the most pronounced differences compared with other cultivars, with higher contents of glycerophospholipids (except PA), PUFA and chlorophylls. White tea cultivars were featured by higher contents of lysophospholipids and very-long-chain-fatty acids. Oolong tea cultivars contained higher abundance of glycoglycerolipids (MGDG, DGDG) and PA, whereas all lipid subclasses were at moderate abundance in black tea cultivars. Through multivariate ROC analysis, 20 lipids were identified as potential biomarkers for stepwise discrimination of manufacturing suitabilities and the predictive accuracies were 100 % using optimal models. Our results provided novel insights into the tea resource evaluation and manufacturing suitabilities.
