identification test | take 5ml of 0.1% sample aqueous solution, add 1ml of indantrione aqueous solution (TS-250), and heat for 3min, it should be purple. Take 0.1g of sample, dissolve with water and fix the volume to 50ml. Take 5μl of the solution for paper chromatographic analysis (GT-10). The expanded solvent consists of n-butanol, glacial acetic acid and water in a ratio of 5:1:2. At the same time, 5μ1 of the control solution was taken for chromatography. The control solution was prepared by dissolving 0.1g L-sodium glutamate and 0.1gL-arginine salt in 100ml of water. When the unfolding solvent of the two groups of chromatographic papers rises to 30cm, they are taken out and air-dried, dried at 100 ℃ for 20min, sprayed with water saturated with n-butanol solution 0.5% indantrione water, heated at 100 ℃ for 5min, and observed in natural light for color. The two color spots of the sample and the pair should be similar. |
content analysis | is the same as the content analysis in "DL-alanine (01102). The equivalent factor (e) in the calculation is 10.71. That is, 1ml of 0.1mol/L perchloric acid solution is equivalent to 10.71mg of this product (Cll H23 N5O6). |
Toxicity | It can be decomposed into L-glutamic acid and L-arginine in the body. High security. |
use | flavoring agent. Mainly used as green tea flavor improver (dosage 1% ~ 2%). Although L-glutamic acid and L-arginine are not essential amino acids, they can be regarded as quasi-essential amino acids for infants and young children because of their poor ability to synthesize L-arginine. L-arginine can improve retinal tissue, so it can be used as a drug. It is used as an amino acid nutritional food additive to treat insomnia, memory loss and fatigue. |
production method | alkaline L-arginine and acidic L-glutamic acid are prepared into a 25-27 bomei degree solution according to the same mol concentration value. after standing at 50 ℃ for 48-72h, the crystal is vacuum dried or spray dried. |
