The linear response range was 0.375 0-12.50 μg·mL-1 for morphine,0.064 32-2.144 μg·mL-1 for codeine phosphate,0.030 06-1.002 μg·mL-1 for papaverine hydrochloride,1.126-37.52 μg·mL-1 for ephedrine hydrochloride,0.287 8-9.592 μg·mL-1 for pseudoephedrine hydrochloride(r = 0.999 7). The average recoveries of these compounds were 99.26%,100.6%,95.29%,100.1% and 97.48%,respectively.
