Study on the Content of Vitamin C in the Tomato by HPLC

In this article,HPLC was performed to research the content of Vitamin C in the tomato.In this way,the content,the repeatability and the returns-ratio of the Vitamin C in the tomato were analyzed under the condition of that ultra-pure water was taken as flowing,and its speed was 1.0ml/min,and the ultraviolet examination wave length was 267nm with the column temperature under the 25℃.The good linear relations were gotten through the linear return with its correlation coefficient being R2=0.9994.Its returns-ratio was 98.71%～103.29%.The relative standard deviation was 0.79%.The method established was simple,fast and accurate,which will be suitable to analyze the content of the Vitamin C in the tomato.
