L-Theanine Cas 3081-61-6

L-Theanine is naturally found in green tea. It can also be obtained by heating L-glutamic acid under high pressure to make pyrrolidone carboxylic acid, adding anhydrous monoethylamine and heating under high pressure.
Theanine (L-Theanine) is a unique free amino acid in tea. L-Theanine is glutamic acid γ-ethylamide, which has a sweet taste. Theanine content varies depending on the variety and part of tea. Theanine accounts for 1%-2% by weight in dry tea.
