Lipid marker composition for distinguishing green tea from white tea as well as screening method and application of lipid marker composition

The invention relates to the technical field of tea distinguishing, in particular to a lipid marker composition for distinguishing green tea and white tea as well as a screening method and application. The invention discloses a lipid marker composition for distinguishing green tea from white tea. The lipid marker composition comprises the following lipid markers: phosphatidyl ethanolamine 36: 6 and monogalactose diacylglycerol 38: 6. The content of the two lipid markers in the green tea is obviously different from the content of the two lipid markers in the white tea. The green tea and the white tea can be effectively distinguished by utilizing the two lipid markers. 本发明涉及茶叶判别技术领域，具体涉及用于区分绿茶和白茶的脂质标志物组合物及筛选方法与应用。用于区分绿茶和白茶的脂质标志物组合物，包括以下脂质标志物：磷脂酰乙醇胺36:6和单半乳糖二酰甘油38:6。上述的2个脂质标志物在绿茶中的含量与在白茶中的含量有明显的差异。利用上述的2个脂质标志物，可以有效区分绿茶和白茶。
