芦荟茶中微量元素锰及其氨基酸含量的测定分析

采用原子吸收分光光度法测定了芦荟保健茶中微量元素锰的含量，氨基酸分析仪测定了17种氨基酸的含量，结果显示芦荟保健茶中含有较高的锰元素和丰富的氨基酸。红茶中锰的含量高于绿茶，其中锰元素在热水中的总溶出率可达50%以上，一次浸泡溶出率＞二次浸泡溶出率＞三次浸泡溶出率。茶中含有7种人体必需的氨基酸，其中较多的是天冬氨酸、谷氨酸、亮氨酸。高锰是该系列保健茶的显著特点。实验结果为探讨芦荟保健系列茶中微量元素和氨基酸与保健功能之间的关系提供了有用的数据。

Determination and Analysis of Trace Element Manganese and Amino Acids Content in Aloe Tea

The content of trace element manganese in aloe tea was determined by atomic absorption spectrophotometry.The contents of 17 kinds of amino acids in aloe tea were determined with amino acids instrumentation.The results showed that there are comparatively rich manganese and amino acids in aloe tea.The content of manganese in red tea is more than in green tea,and the dissolving ratio is more than 50% in boiled water,and first dissolving ratio is more than second dissolving ratio,which is more than third dissolving ratio.There are 7 kinds of amino acids essential to human body,among which are comparatively high(aspartic) acid, glutamic acid and leucine in aloe tea.It's outstanding characteristic is comparatively high content of manganese in aloe health tea.It has provided useful data for probing into the relationship between trace elements and amino acids in aloe health tea and health care function.
