      Simultaneous estimation of piperine and sennoside A in Nilavakai Curanam by HPTLC method
      N. JEGANATHAN*, K. KANNAN (*Annamalai University, Dept. of Pharmacy, Nagar 608002 (T.N.), India)

      Ind. J. Pharma Educ. Res. 42(1), 59-64 (2008). Curanams are an important group of formulations in ayurvedic and siddha medicine. HPTLC of sennoside A and piperine in methanolic and ethyl acetate extracts of Nilavakai Curanam on silica gel with n-hexane - ethyl acetate - formic acid - acetic acid 15:5:1:1. Quantitative determination by absorbance measurement at 254 nm. The methanolic extract of the laboratory formulation contained 0.61 % and 1.4 % piperine and sennoside A respectively, whereas the ethyl acetate extract contained 1.0 % and 4.2 %. The methanolic extract of the commercial formulation contained 0.27 % and 0.42 % and the ethyl acetate extract contained 0.27 and 0.53 % respectively. The method was linear in the range of 15-105 ng/spot and 5-30 ng/spot for piperine and sennoside A respectively. The recovery was 98.5 % for both compounds.

      J. AOAC Int. 91, 1154-1161 (2008). HPTLC of 3 key whithanolides, namely withaferin-A, 12-deoxywithastramonolide, and withanolide-A on silica gel with dichloromethane - methanol - acetone - diethylether 15:1:1:1 in a saturated twin-trough chamber at 25 °C and relative humidity of 35-40 %.

      Interfaces To Connect Thin-Layer Chromatography with Electrospray Ionization Mass Spectrometry
      F.L. HSU, C.H. CHEN, C.H. YUAN, J. SHIEA* (*Department of Chemistry, National Sun Yat-Sen University, Kaohsiung, Taiwan, jetea@mail.nsysu.edu.tw)

      Anal. Chem. 75, 2493-2498 (2003). Development of two interfaces to connect small-size thin-layer chromatography with electrospray ionization mass spectrometry (ESI-MS) for the continuous analysis of organic mixtures. The interfaces were 1) two bound optical fibers inserted into the RP-18 particles at the exit of a small TLC channel; 2) a small commercial TLC strip with a sharpened tip. A reservoir continuously supplied a makeup solution to the tip of the TLC channel. The high voltage required for electrospray ionization was introduced into the makeup solution or mobile phase through a Pt wire, and electrospray was generated at the tip of the bonded optical fibers and at the sharp end of the TLC strip. Since small-size TLC channels were used, the elution time was short and less than 0.2 µL of sample solution and 200 µL of solvent were required.

      A new chromogenic spray reagent for detection and identification of monocrotophos
      K.V. KULKARNI*, D.B. SHINDE, D.V. MANE, M.V. GARAD (*Regional Forensic Science Laboratory, Dindori Road, Panchvati, Nasik 431004, India; krishnakulkarni96@yahoo.com)

      J. Planar Chromatogr. 22, 133-135 (2009). HPTLC of monocrotophos on silica gel with chloroform - acetone 7:3 with chamber saturation. Detection by spraying with 20 % sodium carbonate followed by acidic methanolic iron chloride reagent. Evaluation of purple spots, while organophosphorus, organochlorine, carbamate, and pyrethroid insecticides were not detected as purple spots. Alkaline hydrolysis of monocrotophos yields one molecule each of O,O-dimethylphosphoric acid and N-methylacetoacetamide. After acidiification N-methylacetoacetamide yields the enol form of monomethylamide which reacts with ferric ions to a purple complex. The detection limit for monocrotophos is 0.5 µg/zone.
