Retention data were standardized by the calculation of relative retention times using N, N-dlisopropyl-n-dodecane as the internal standard. The relative standard deviations of retention times were less than 0.5% for the within batch analyses and less than 0.8% for the day-to-day analyses. Good recoveries (> 70%) were observed for most of the drugs. ？ 1990 Oxford University Press.
