Pharmaceutical Intermediates(L-theanine)

About L-theanine: Name:L-theanine CAS:3081-61-6 Molecular:C7H14N2O3 Residue on ignition:≤0.2% Chloride:≤0.05% Loss on drying:≤0.5% Heavy metal(Pb): ≤10ppm Arsenic:≤4ppm Ph:5.0-6.5 Melting point:202-215°C MW:174.2 Purity:99%min New Production methods: Bio-Enzymatic The L-theanine is mainly used in the Pharmaceutical Intermediates in the following aspects: (1),The L-theanine can be used as an antitumor medicine. The animal experiment proves that the theanine can extend the transferability of the tumor of the mice and the time of the survival time of those with leukemia. (2),The L-theanine can reduce the pressure. The animal experiment shows that the systolic and diastolic pressure of artificial-pressure-rising mice which have taken the theanine can be decreased. (3),The L-theanine can be added to the soothing medicine. It has been regarded as the effective element of the soothing medicine and can prevent the parkinson's disease, alzheimer disease and conduction nerve dysfunction. The comparision of L-theanine through the process enzyme synthesis with through the process of chemical synthesisL-Theanine through the process of microbe ferment is all L type,because of special and distinctive effect of microbe enzyme.Specific Rotation [α]20/D of our product is +8.2-+8.3degreeDuring the process of microbe ferment,we do not add any chemistry reagent .The raw material of production are L-Glutamine and ethylamine.so do not worry about the safety of our product.All the raw materials of our product are food grade.
