| Abstract: | OBJECTIVE To develop a HPLC method for the determination of mycophenolate mofetil and its related sub-stances. METHODS Theseparation was perform ed on an Agilent XDB-C8 column（4.6nm×150mm,5μm）, and the mobilephase consisted of acetonitriie and 0.1% trifluoroacetic acid solution（adjusted to pH 3.9 with triethylamine）（35：65）at the flow rate of 1.0mL·min^-1. The detection was carried out at 250nm. RESULTS An excellent separation was achieved for mycophenolate mofetiland its related substances. The method was validated in the concentration range of 4.9--157.2mg· L^-1, （r= 0. 9999）. The RSDS of intraday and interday precision were 0.65% and 1.02% .CONCLUSION The method developed is successfully used to determinemycophenolate mofetil and its related substances. |
