| Abstract: | Summer and autumn green tea varieties Fuding and Zhuyeqi were chosen to study Mn content and Mn extracting rate. The results showed that the Mn content in summer and autumn green tea was 1876.8 -2337.4 mg/kg; the changeable trend of Mn content was similar in both Fuding and Zhuyeqi. Mn content was the highest in late August, while lower in early July and middle September;the Mn extracting rate in Fuding and Zhuyeqi was 35.3% -42, 7% ,Mn extracting rate in Zhuyeqi was higher than that in Fuding. As the time went on, the Mn extracting rate in Zhuyeqi decreased, while increased in Fuding. |
