摘要: 目的:建立HPLC法测定龙眼肉中腺苷、尿苷和腺嘌呤的含量。方法:采用NucleosilC18反相柱(250mm×4mm),以0.01mol/L的KH2PO4:乙腈=92:8为流动相,流速为1ml/min,检测波长为254nm,柱温40℃,用外标法,测定了龙眼肉中腺苷、尿苷和腺嘌呤的含量。结果与结论:分析中选取腺苷的线性范围0.1~20.0μg/ml,相关系数r=0.9999,回收率94.59%,RSD3.10%;尿苷的线性范围0.05~10.0μg/ml,相关系数r=1,回收率97.49%,RSD4.50%;腺嘌呤线性范围0.05~10.0μg/ml,相关系数r=1,回收率103.11%,RSD1.90%。该方法简便快速,线性关系良好。

Abstract: Objective: To determine the content of adenosine, uridine and adenine in Dimocarpus longan Lour. Methods: The HPLC method was used to determine respectively the content of adenosine, uridine and adenine in Dimocarpus longan Lour. The analysis was carried out on Nucleosil C18 column(250mm×4mm). The mobile phase was 0.01mol/L KH2PO4-CH3CN (92:8, V/V), flow-rate 1.0ml/min, wavelength 254nm and temperature 40℃. Results and conclusion: The method is simple and has a good linear relationship. The linear range of adenosine is 0.1~20.0μg/ml and gives a correlation of 0.9999.The recovery of adenosine is 94.59% and RSD 3.10%. The linear range of uridine is 0.05~10.0μg/ml and gives a correlation 1. The recovery of uridine is 97.49% and RSD 4.50%. The linear range of adenine is 0.05~10.0μg/ml and gives a correlation of 1. The recovery of adenine is 103.11% and RSD 1.90%. The method is easy to determine the content of several kinds of nucleotide in Dimocarpus longan Lour by HPLC.
