Abstract
[Objective]The research aimed to identify the Mengding Ganlu tea from different seasons.[Method]61 Mengding Ganlu tea sam-ples which using the same manufacturing technology from spring, summer and autumn of Ya'an area were determined by national standard methods,the ratios of tea polyphenols to theanine were calculated,and the differences of the ratio of tea samples in different seasons were ana-lyzed.[Result]The ratio of tea polyphenols to theanine in the summer-autumn tea concentrated in more than 15,while the ratio of tea polyphe-nols to theanine in the spring tea was below 15.[Conclusion]The ratio of tea polyphenols to theanine was good for distinguishing spring tea from summer-autumn tea.The Mengding Ganlu tea can be judged as spring tea when the ratio of tea polyphenols to theanine is below 15 and can be judged as summer-autumn Mengding Ganlu tea when the ratio of tea polyphenols to theanine is more than 15.关键词
