Outline
To improve and perfect the quality standards of rice water to ensure the stable quality of rice water processed traditional Chinese medicine decoction pieces.
The clarification and pH value of rice water were determined. Using L-lysine as the control substance，thin layer chromatography（TLC）was used to qualitatively identify the rice water. The total amino acid content and enzyme activity were determined by ultraviolet-visible spectroscopy（UV）method.
The turbidity values of the 10 batches of samples ranged from 2. 280-3. 412. The pH values of the 10 batches ranged from 6. 14-6. 58. The TLC spots were clear and repeatable. The linear range of the total amino acid was 5.31-53. 1μg（r=0.999 0），and the recoveries were 97.54%-100.1%（RSD=0.9%）. The total amino acid content was 1.19-1.47 mg·mL-1，and the enzyme activity was 5.42-6.37 U·L-1.
The quality control method of rice water was improved. The method is accurate，stable and reproducible，and can be used for the quality control of rice water.
