ABSTRACT

<p><b>OBJECTIVE</b>To determine the contents of amino acids in Cornu Cervi Pantotrichum of different specifications for controlling the quality.</p><p><b>METHOD</b>The contents of 18 kinds of amino acids were determined by amino acid analyzer.</p><p><b>RESULT</b>The correlation coefficients of 18 kinds of amino acids were all greater than 0.997, the average recovery were all between 99.1%-108.1% with RSDs less than 2.0%. All Cornu Cervi Pantotrichum samples of 29 different specifications contained 17 kinds of amino acids and 7 kinds of essential amino acids. The content of total amino acids in wax slices is relative higher. The content in first born antlers is higher than that in reborn antlers.</p><p><b>CONCLUSION</b>This method is suitable for the determination of amino acids in Cornu Cervi Pantotrichum, it provides good reference for the quality control of Cornu Cervi Pantotrichum.</p>
