| Abstract: | The application of Paper Electrophoresis-chromatography to multiple Analysis on Gamma-aminobutyric Acid in Tea within Test Period was improved in this experiment.The variance ratio of results from the assay for GABA content within 5 piece of tea samples was less than 10% and the recovery ratios of standard GABA adding to the tea samples was 100.30±2.36%.There was no significant difference between the test results for GABA in tea from the improved method and those from the amino-acid automatic analysis-meter. |
