      Pressurized liquid extraction and anticholinesterase activity-based thin-layer chromatography with bioautography of Amaryllidaceae alkaloids
      T. MROCZEK*, J. MAZUREK (*Dep. of Pharmacognosy with Med. Plant Lab. Unit, Med. Univ., 1 Chodzki St., 20-093 Lublin, Poland)

      Anal. Chim. Acta 633 (2) 188-196 (2009). HPTLC of lycorine and galanthamine from Narcissus jonquilla ‘Pipit’ on silica gel with chloroform - methanol - 25 % ammonia 18:1:1. Quantitative evaluation by absorbance measurement at 207 nm. The correlation coefficients were r=0.9882 and 0.9908, respectively, for the mean values of galanthamine and lycorine. Investigation of different extraction solvents showed that extraction with methanol and 1 % tartaric acid in methanol at default conditions (120 °C, p = 60 bar, time: 10 min, one static cycle) provide the highest yields of total alkaloids, whereas for toluene the lowest amounts were measured. Lycorine to galanthamine mean ratios were dependant on the type of solvent used, and in toluene galanthamine and related alkaloids were preferably extracted.
