Abstract
|
|
|
Chemical constituents and amino acid contents of tea leaves which were harvested three times (May, July and August) from the tree at two different locations were studied.
The contents of total nitrogen, ascorbic acid and amino acid decreased, while those of fiber and tannin increased in the order of May, july and August crops.
No differences were observed in the contents of reducing sugar, caffeine and ash among tea leaves harvested at different times.
There were no effects of locations on the contents of chemical constituents of tea leaves.
