Abstract:
Objective To develop the method for simultaneous identification and quantification of morphine,6-monoactylmorphine,codeine,heroin,ketamine,3,4-Methylenedioxyamphetamine (MDA),3,4-methylenedioxymethamphetamine (MDMA),amphetamine and methylamphetamine in human plasma.Methods UPLC-MS/MS was adopted to analyze plasma with protein precipitated using 10％ trichloroacetic acid.Plasma samples were separated on ACQUITY UPLC HSS C18 column with aqueous solution (0.01％ formic acid)-methanol (0.01％ formic acid) as the mobile phase,and at a flow rate of 0.3 mL·min-1.The multiple reaction monitoring (MRM) mode was performed combined with the positive ion mode for quantification in four sections.Results The retention time,the characteristic fragment ions,and the relative abundance ratio of the molecular ion peak could be used to identify these nine compounds sensitively.The liner calibration curve of morphine,codeine,heroin,ketamine,6-monoacetylmorphine,MDA,MDMA,amphetamine and methamphetamine were obtained in the concentration range of 5.00×10-3～5.00 (r=0.9934),1.00× 10-2～ 10.00 (r=0.9905),1.00× 10-2～ 10.00 (r=0.9929),2.50× 10-3 ～2.50 (r=0.9960),5.00× 10-3 ～ 5.00 (r=0.9925),5.00× 10-4 ～ 5.00 (r=0.9910),5.00× 10-4 ～ 5.00 (r=0.9924),5.00× 10-4 ～ 5.00 (r=0.9920) and 5.00×10-4～5.00 μg·mL-1 (r=0.9900) respectively.The lowest detection limit was 1.00,1.00,1.00,0.50,0.50,0.10,0.10,0.10 and 0.10 ng· mL-1 respectively.The relative standard deviation (RSD) of the inter-day and intra-day were less than 18％.The relative recovery was more than 60％,and the RSD were less than 15％.Conclusion The method is accurate,sensitive and suitable for identification and quantification of 9 drugs of opiates,ketamine and amphetamines in human plasma.
