There are more
than 400 kinds of substances in tea, the most important of which are: protein,
alkaloids, amino acids, tea polyphenols, etc.
Today we talk about the main ingredient in tea alkaloids, caffeine, which was first discovered in coffee. With the study of tea, the content of caffeine in tea is higher than that in coffee, and the content of caffeine in coffee is 1%-2. About %, and the content of caffeine in tea is about 2%-5%. It accounts for more than 95% of the total alkaloids of tea. Like the amino acids of tea, it is an important substance in the nitrogen cycle of tea plants. In fact, caffeine has a close relationship with the growth and metabolism of tea trees. Where is the new growth of tea, where the content of caffeine is more; the season of tea tree grows faster, and the content of caffeine in which season is more. The newer, more tender part of the tea tree contains more caffeine, and the caffeine will be decomposed as the growth time increases. Therefore, the older the raw material, the less the caffeine. The summer temperature is higher, the tea tree grows most vigorously, and the summer tea contains the highest caffeine.
Most of Pu-erh tea belongs to large-leaf tea trees, and the sunshine time and temperature are more suitable for tea tree growth. The content of caffeine is the highest in tea, which is bitter than other regions and types of tea, especially new tea.
The caffeine will decompose, and the caffeine that continues to grow will automatically decompose during the growth process. The main route is: caffeine or other purine----uric acid---allantoin----uric acid--- -- Urea - carbon dioxide (gas). However, the conversion of caffeine into the human body is not the same as: caffeine or other purines - jaundice - uric acid. Need to be taken out of the body through human metabolism.

Caffeine has the effect of refreshing, clearing heat,
reducing fire and relieving pain. Excessive intake of caffeine can cause
excitement, convulsions and other reactions, so it is not appropriate to
consume excessive caffeine. Caffeine is easily soluble in hot water. It has
been proved that more than 60% of the caffeine in tea leaves is soaked in tea
leaves for about 1.5 minutes. After soaking, the bitterness of tea can be reduced
without affecting other ingestion of beneficial substances in tea leaves.
Drinking tea as a healthy drink can achieve good health results through scientific and rational use.
