      J. of Chromatogr. B 879 (30), 3565-4573 (2011). Presentation of a novel “target constituent knock-out” strategy applied for preliminary screening of antibacterial constituents in Calculus bovis. The strategy contained the following steps: 1) the single constituents (A-F) in C. bovis samples were knocked out by TLC on silica gel with toluene - acetic acid - water 30:25:2, detection under UV 366 nm; 2) the knocked-out constituents were identified by UPLC–ELSD; 3) the antibacterial activities of the knocked-out constituents and C. bovis samples on Staphylococcus aureus were evaluated by microcalorimetry combined with principal component analysis; 4) the activities of the knocked-out constituents and the total extract of C. bovis, also the interaction properties between these single constituents and the total extract were elucidated. The strategy proved to be useful for screening active constituents and elucidating the multi-component interactions in C. bovis, and helpful in understanding the pharmacodynamic actions and the quality control of traditional Chinese medicines.

      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.
