绿茶中氨基酸分析

The Biochrom 30 Amino Acid Analyser is a well
established analytical instrument for clinical
diagnosis as its IVD approval allows the diagnosis
of inborn errors of metabolism such as
Phenylketonuria.
This robust and reliable instrument is also capable
of other types of applications far from the clinical
market e.g. its usage in the food industry allows
routine analysis of amino acid content in food and
feedstuff in quality control laboratories.
The Biochrom 30 can also be used for analysing
rare, unusual amino acids or derived molecules for
research purposes.
In order to develop new methods for analysing
molecules of interest in the scientific market, a
new application has been developed to analyse
the theanine content in green tea leaves.
Theanine is a molecule derived from the amino
acid glutamine and is usually found in tea
(infusions of Camellia sinensis), and also in the
basidiomycete mushroom Boletus badius.
Because it can enter the brain, theanine has
psychoactive properties. Theanine has been
shown to reduce mental and physical stress, may
produce fee领s of relaxation, and improves
cognition and mood when taken in combination
with caffeine. These effects are believed to be
caused by the ability of theanine to increase GABA
production in the brain.
The chemical structure of theanine allows it to be
separated and detected in green tea samples
using a Biochrom 30 Amino Acid Analyser. Biochrom 30+ 全自动氨基酸分析仪
