OBJECTIVE To develop an HPLC-MS METHOD for qualitative and quantitative analysis of nine antiviral agents illegally adulterated in traditional Chinese medicines. METHODS The samples were separated on a CAPCELL PAK CR 1∶4 column(2.0 mm×150 mm, 5 μm) by gradient elution with 0.1%formic acid solution(adjusted to pH 3.5 with ammonium hydroxide)as the mobile phase A and acetonitrile as the mobile phase B. The gradient elution program was as follows:0-12 min(90%A→48%A), 12-15 min(48%A→20%A), 15-19 min(20%A→15%A), 19-20 min(90%A).　The flow rate was 0.2 mL·min^-1 and the injection volume was 5 μL . After being separated by HPLC, the test solution was analyzed by mass spectrometer operated in positive ion mode and in product mode and SRM mode. RESULTS The calibration curves of the nine antiviral agents showed good linearity and the correlation coefficients were more than 0.998. The recoveries at 3 spiked levels were in the range of 80.6%-117.7%. The limits of quantification were in the range of 0.1-1 μg·g^-1. The fragmentation pattern of the nine antiviral agents was summarized. CONCLUSION The METHOD is sensitive, specific, accurate and applicable to detect the nine antiviral agents in traditional Chinese medicines.
