Abstract

Sodium alendronate is one of biphosphonate group drugs for the treatment of osteoporosis,. The aim of this research was to obtain the optimum condition for forming derivative of sodium alendronate with dansyl chloride. By adding 270 μL dansyl chloride to 0.1 M sodium carbonate buffer at pH 10.0 mixing with thermomixer at 50.oC for 50 minutes, resulted in a stable derivative within 30 minutes. The compound was analysed by high performance liquid chromatography method using C18 column acetonitrilemethanol-buffer (25 mM KH2PO4 and 25 mM citric acid) (20:15:65;v/v) as mobile phase at a flow rate of 1.0 mL/minute; (detected at wavelength of excitation 320 nm and emission 495 nm). The retention time of the derivative was 19.758 minutes, the calibration’s curve was linear at concentration range of 0.2-1 μg/mL with coefficient of correlation (r) 0.9995 and limit of quantitation 0.114 μg/mL.Key word : HPLC, sodium alendronat, dansyl chloride, fluorescence

Abstract

Determination of sibutramine adulterated in herbal slimming product using thin layer chromatography (TLC) densitometric method with TLC silica gel 60 F254 aluminium plate as stationary phase and mixture of toluen-diethylamine (10:0.3) as mobile phase has been developed. The calibration curve in the concentration range of 0.50 to 5.00 µg/spot showed good linier relationship (r2 = 0.9986). The limit of detection and quantitation (LOD and LOQ) were 217.5 ng and 724.9 ng/spot, respectively. The method gave satisfactory specificity, linierity, precision and accuracy validation criteria and was applied for determination of sibutramine in herbal slimming products obtained from several drugstrores in Depok City, West Java, Indonesia. Results of the determination showed that six of seven samples analyzed were detected containing sibutramine HCl with the concentration of 2.45 - 26.24 mg in a single dosage of slimming herbal products
