查询词典 sod

The main chemical compositions of tea flower were studied. It is the first time to determine the levels of protein, reducing saccharides and SOD activity in different blooming stages of tea flowers collected from three cultivars of Camellia sinensis with different picking time. Results showed that there were significant differences among cultivars and blooming stages, as well as the change of these chemical constituents along with time. Consequently we selected the right cultivar that has high protein, reducing saccharides or SOD activity and the fitting deflower time.
