Abstract: The level of theanine biosynthesis of tea cultured cells initiated from different explant material and the dynamics of theanine biosynthesis in tea suspension cell were analyzed. The suitable medium for theanine biosynthesis and the effect of medium renewal were also tested. According to the result, the peak of theanine accumulation was appeared on the 11th day during a culture cycle. But if the medium was renewed in an interval of 10 days, theanine could be continuously accumulated in the cells until about the 30th day and reached a high peak of 20% cell dry weight.
