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.

本文研究了茶花中主要化学成分的含量，首次对不同茶树品种、开花状态和采摘时间的茶花中蛋白质、还原糖含量，以及SOD活力进行系统研究，明确了不同茶树品种、不同开花状态茶花中蛋白质、还原糖含量和SOD活力的差异，以及这些化学成分随时间的变化规律，从而筛选出了高蛋白质、还原糖含量，以及高SOD活力的茶树品种和适宜的采花时间。
