      IPC 56th 2004, Abstract No. DP-33. An HPTLC method is reported for the standardization of Trikatukuc Curanam, an Ayurvedic preparation with Piper nigrum and Piper longum, both containing piperine as major alkaloid. HPTLC of piperine on silica gel with toluene - ethyl acetate 7:3 .Extraction with methylene chloride, the evaporated residue of the organic layer was taken in ethyl acetate and subjected to the analysis.The band corresponding to piperine was scanned at 338 nm. Linearity was 8-40 ng with recovery of 99.03 %.

When using phase B repeated development improved the resolution. After development the plates were dried in a vacuum chamber at 100 °C. An efficient prewashing technique (with methanol - 35 % formic acid 1:1 followed by drying with hot air) made the TLC plates suitable for densitometric measurements at short wavelengths. Quantitative determination by absorbance measurement at 200 nm.

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.
