      Fluorescence detection combined with either HPLC or HPTLC for pharmaceutical quality control in a hospital chemotherapy production unit
      G. EDMOND, B. PHILIPPE, M. LIONEL, P. ANGELO* (*Dept. of Clinical Pharmacy, Institut Gustave Roussy, 39, rue Camille Desmoulins, 94800 Villejuif, France)

      J. Pharm. Biomed. Anal. 39, 581-586 (2005). For post-production quality control of camptothecin derivatives irinotecan (CPT 11) and topotecan (TPT), HPLC and HPTLC methods have been developed which were suitable for identification, determination of purity and quantification. HPTLC on silica gel with methylene chloride - methanol - formic acid - water 82:24:2:1. After development, the plate was soaked in 15 % paraffin in n-heptane. Quantitative determination by fluorescence measurement at 366/>400 nm. The method was linear within the range of 100-1000 ng/mL for both CPT-11 and TPT. The method was validated for accuracy, precision, LOD, and LOQ.

      J. AOAC Int. 88, 1549-1554 (2005). TLC of polymyxin B, framycetin, and dexamethasone on silica gel with methanol and methanol - n-butanol - 25 % ammonia - chloroform 14:4:9:12 for framycetin and polymyxin B. Quantitative determination by densitometry at 550 nm after detection with 0.3 % ninhydrin solution. Dexamethasone was separated with cyclohexane - ethyl acetate 2:3, quantitative determination by absorbance measurement at 245 nm. Similar accuracy, relative standard deviation values from 1.49 to 2.47 % and relative error values from 0.02 to 0.81 % are comparable to those obtained with the reference methods.

      HPTLC method for determination of ursolic acid from Oscimum sanctum Linn (Tulsi) leaves and its formulations
      J.K.VERMA*, A.V.JOSHI (*Dept. of Chemistry, K.J.Somaiya College of Sc & Comm, Vidyavihar, Mumbai 400077, India)

      Indian Drugs 42 (10), 650-653 (2005). A simple rapid, precise and cost-effective HPTLC method has been developed for the determination of ursolic acid in Oscimum sanctum (Tulsi) leaves and its formulations (Tulsi ghan tablets and Tulsi capsules). HPTLC on silica gel with toluene - ethyl acetate - acetic acid 30:3:1. Detection with anisaldehyde in sulphuric acid reagent followed by heating in an oven at 110 °C. Quantitative determination by absorbance measurement at 580 nm. Linearity of the detector response was given in the range of 40 - 280 ng. LOD was 8 ng. The correlation coefficient obtained from linearity was 0.9985. The standard error was 26.511. The mean assay values of ursolic acid wa found to be 3.485 mg/g, 0.553 mg/g and 3.221 mg/g in tulsi ghan tablets, tulsi capsule and tulsi leaves respectively.
