| 摘 要： | 比较了沸水、0.1 mol·L-1盐酸、甲醇、无水乙醇、85％乙醇、60％乙醇等不同溶剂提取茶叶中氨基酸的效果,结果以60％乙醇超声波法提取60 min最好；比较了用6 mol·L-1盐酸采用电磁水解法和超声波法提取茶叶中氨基酸的效果,电磁水解法优于超声波法,但电磁水解法对含硫氨基酸破坏较大.

| Abstract: | The extraction methods of amino acid in tea by boiling water,0.1N hydrochloric acid,methyl alcohol,anhydrous alcohol,85% alcohol and 60% alcohol were compared.The result showed that the best effect was by ultrasonic extraction in 60% alcohol within 60 min.The methods with electromagnetism hydrolysis and ultrasonic were compared.The result showed that the electromagnetism hydrolysis method was excellent than ultrasonic wave method,but sulfur-containing amino acids were destroyed by electromagnetism hydrolyti... |
