      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).

      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.
