      R.T. SANE*, M. GADGIL, (*S.P. Mandali's Ramnarain Ruia College, Matunga (East), Mumbai 400 019, India)

      J. Planar Chromatogr. 15, 76-78 (2002). HPTLC of paracetamol (N-(4-hydroxyphenyl)acetamide), chlorzoxazone (5-chloro-2(3H)-benzoxazole), and nimesulide (N-(4-nitro-2-phenoxyphenyl) methane sulfonamide) on silica gel - after prewashing with 10% triethylamine in methanol with chloroform - methanol - toluene 12:2:3. Densitometry at 270 nm. The proposed method is highly accurate, selective, and precise and can therefore be used for a routine quality-control analysis.

Quantification by densitometry at 348 nm via linear regression in the range of 40-220 ng. Limit of quantification and limit of detection were found to be 30 ng and 10 ng, respectively. The herbal extract was found to contain 0.402 % w/w of berberine. The percentage of berberine in formulations I, II, III and IV were 0.0886 %, 0.0123 %, 0.0283 % and 0.0091 % w/w, respectively. The standardized method was found to be reproducible, accurate, precise and selective.
