title: [Determination of sisomicin in body fluid by high performance liquid chromatography-indirect photometric detection method].
abstract: A high performance liquid chromatography-indirect photometric detection (HPLC-IPD) method for determination of sisomicin sulfate in body fluid (serum, urine, saliva, cerebrospinal fluid and fluid oozed out from wound) was established. The conditions in this method were a mobile phase solution of methyl alcohol-acetonitrile-water (20:10:70) containing nicotinamide 0.5 mmol/L, sodium 1-heptanesulfonate 5 mmol/L and phosphoric acid 0.05 mol/L, a Spherisorb C18 column (4.6 mm x 250 mm) and an UV detector with sensitivity of 0.05 Aufs (0.1 Aufs for urine). The detection wavelength was fixed at 268 nm. The average recovery for sisomicin in serum was 96.92% +/- 4.63% and the coefficients of variation were 4.75% and 5.65% for within-day and day-to-day tests respectively. The detectable limit was 0.1 ng. The concentration of sisomicin in body fluid of 4 patients was determined.
