      Comparative phytochemical investigation of the sources of Ayurvedic drug Patha
      K. HULLATTI*, M. SHARADA (*Dept. for Pharmacognosy, National College of Pharmacy, Shimoga-577201, DOS in Botany, Univ. of Mysore 570006, India, kkhullatti@gmail.com )

      Ind. J. Pharma. Sci. 72(1), 39-45 (2010). The Ayurvedic Pharmacopoeia of India recognized roots of the three plants Cissampelos pareira, Cyclea peltata, and Stephania japonica (all Menispermaceae) as source for the marketed drug Patha. HPTLC fingerprint analysis of methanolic extracts of roots of all three plants on silica gel with n-butanol - ethyl acetate - formic acid - water 3:5:1:1. Detection under UV 365 nm (crude extract) and 295 nm (total alkaloids). Quantification of the marker berberine by HPLC. The three plants exhibit significantly different physico-chemical features and chromatographic fingerprints. Roots of C. pareira contained the highest concentration of berberine, S. Japonica contained very low amounts and C. peltata no berberine at all.

      Selective densitometric determination of four alpha-aminocephalosporins using ninhydrin reagent
      G.A. SALEH, F.A. MOHAMED, S.R. EL-SHABOURY, A.H. RAGEH* (*Department of Pharmaceutical Analytical Chemistry, Faculty of Pharmacy, Assiut University, 71526 Assiut, Egypt)

      J. Chromatogr. Sci. 48, 68-75 (2010). TLC of cefaclor, cefadroxil, cefalexin and cefradine on silica gel with ethyl acetate - methanol - water in different ratios. The studied drugs had hRf values between 40 and 60. Detection of blue to violet colored zones after spraying with ninhydrin reagent. Quantification by densitometry. Linearity was in the range of 2-10 µg/zone with correlation coefficients ranging from 0.9990 to 0.9996 and determination coefficients from 0.9986 to 0.9992 for all studied drugs. The limits of detection and quantification for all studied drugs were between 90 to 230 ng/zone and 270 to 840 ng/zone, respectively.

      Thin-layer chromatography with biological detection in phytochemistry
      A. MARSTON (Chem. Dep., Univ. of the Free State, Bloemfontein 9300, South Africa)

      J. of Chromatogr. A 1218 (19), 2676-2683 (2011). A review on bioautography on TLC plates as an important means of detecting the biological activity of a sample. The technique requires only small amounts of sample, is ideal for the investigation of plant constituents which often occur as complex mixtures, and can be used for the target-directed isolation of these constituents. In contrast to HPLC, many samples can be run at the same time on TLC, and organic solvents, which cause inactivation of enzymes or death of living organisms, can be completely removed before biological detection. Many bioassays are compatible with TLC and antimicrobial, radical scavenging, antioxidant activities and enzyme inhibition tests can be applied.

      Densitometric HPTLC and HPLC analysis of phenolic acids from Aquilegia vulgaris
      M. SZAUFER-HAJDRYCH*, W. BYLKA, I. MATLAWSKA, M. WÓJCIAK-KOSIOR, G. MATYSIK, J. JODYNIS-LIEBERT (*Poznan University of Medical Sciences, Department of Pharmacognosy, Swiecickiego 4, 61-771 Poznan, Poland)

      Acta Chromatographica 20(4), 685-695 (2008). Determination of p-coumaric and protocatechuic acids in an ether fraction from a methanolic extract of Aquilegia vulgaris L. by HPTLC on silica gel with mixtures of heptane, dichloromethane, diisopropyl ether, formic acid, and water in various ratios. Satisfactory separation of the phenolic acids was achieved by use of the multiple gradient development technique. HPTLC results of the quantities of p-coumaric and protocatechuic acids were somewhat higher (0.396 and 2.584 mg/g dry plant material, respectively), than those determined by HPLC (0.374 and 2.283 mg/g dry plant material, respectively). Both methods were satisfactory in the precision, expressed as relative standard deviation, and are useful for quality control of Aquilegia vulgaris extracts.
