      J. Liq. Chromatogr. Relat. Technol. 41, 15-16 (2019). HPTLC of thymine (1), uracil (2), adenine (3), cytosine (4), guanine (5) and guanosine (6) in Ganoderma lucidum and Cordyceps sinensis on silica gel with dichloromethane - methanol - formic acid 160:45:16. Quantitative determination by absorbance measurement at 254 nm. Identification of nucleobases in the samples was reconfirmed by hyphenated HPTLC-MS. The hRF values for (1) to (6) were 83, 73, 46, 32, 23 and 10, respectively. The intermediate precision was below 5 % (n=3).

      J. Chromatogr. A 1209 (1-2), 230-237 (2008). TLC of purines (adenosine and its major metabolites, inosine, and hypoxanthine) in rat brain tissue preparations, on silica gel with a two-step gradient mobile phase consisting of (1) n-butanol – water – acetonitrile - 10% ammonia - acetic acid 10:4:8:2:1 and (2) n-butanol – chloroform – acetonitrile - 10 % ammonia - acetic acid 10:4:8:2:1. Quantitative determination by absorbance measurement at 258 nm (via peak area). Application of the method to estimate the endogenous purines in discrete regions of rat brain. Development of a novel protocol for tissue preparation using 0.1 M HCl and 0.15 M NaOH solutions in 60 % methanol, which provided well-resolved peaks and high recoveries.

      RM and log P values. J. Chromatogr. 498, 179-190 (1990). Measurement of the RM values of a series of xanthine and adenosine derivatives on silicone-impregnated silica and C-18 silica with aqueous glycine buffers (pH 9.0) or sodium acetate veronal buffer (pH 7.0), alone or mixed with various amounts of acetone. Correlation of the two series of data obtained. Comparison of experimental log p values with calculated ones. The TLC data proved to be reliable for describing the lipophilic properties of the test compounds.
