      HPTLC estimation of tizanidine and diclofenac sodium in combination tablets
      M. SENTHIL*, G. SUBRAMANIAN, M. VASUDEVAN, S. RAVISANKAR (*Manipal College of Pharmaceutical Sciences, Manipal 576104, India)

      Indian Drugs 42 (7), 465-468 (2005). HPTLC of tizanidine and diclofenac in tablet formulations on silica gel with chloroform - methanol 4:1. Quantitative determination by absorbance measurement at 230 nm. Cetrizine was used as an internal standard. The solvent system was found to give compact spots for diclofenac sodium (Rf value 0.86), tizanidine (0.26) and cetrizine (0.52). The method was validated for linearity, accuracy and precision. Linearity for tizanidine was 0.6-1.4 µg/mL, and for diclofenac sodium 7.5-17.5 µg/mL . The mean recoveries obtained for tizanidine and diclofenac sodium were 98.73 % and 99.70 %, respectively. The proposed method was accurate, precise, selective and rapid for simultaneous estimation of tizanidine and diclofenac sodium in tablets.

      using high-performance thin-layer chromatography. J. AOAC Int. 89, 1467-1474 (2006). HPTLC of eugenol, luteolin, ursolic acid, and oleanolic acid on silica gel in a twin trough chamber with toluene - ethyl acetate - formic acid 35:15:1 at 25 °C and 40 % relative humidity. Quantitation in absorbance mode at 280 nm for eugenol, at 350 nm for luteolin, and at 530 nm for ursolic acid and oleanolic acid after derivatization with anisaldehyde-sulfuric acid reagent and heating at 105°C. The methods were validated for precision, repeatability, and accuracy.

      Occurrence and activity of natural antioxidants in herbal spirits
      C. IMARK, M. KNEUBUEHL, S. BODMER* (*Biodyn GmbH, Industriestrasse 31, CH-8305 Dietlikon, Switzerland, bodmer@biodyn.ch)

      Innovative Food Science and Emerging Technologies 1, 239-243 (2001). HPTLC of commercial herbal spirits (alcoholic or hydroalcoholic solutions of volatile substances with flavoring or medicinal properties) and one red wine on silica gel with toluene – ethyl formate – formic acid 79:20:1. Antioxidative components were detected by dipping for 30 s in a soybean oil solution (3 % in n-hexane, previously treated with active carbon). Quantitative determination in UV light at 254 nm after different times of UV-exposure (30 min – 20 h). The antioxidant activity could be evaluated from the fluorescence-persisting time of the respective spots and was correlated with linoleic acid oxidation and DPPH-titration methods. Although the nature of the active herbal antioxidants remains to be established, phenolic compounds seem to be key candidates.
