J. Planar Chromatogr. 21, 299-304 (2008). HPTLC of 21 amino acids on silica gel impregnated with 5 % Ag ion with borate phosphate buffer pH 2.3. After drying at 50 °C detection by spraying with ninhydrin. With this system separation of alanine, phenylalanine and tryptophane could be achieved, as well as separation of alanine, tyrosine and tryptophan. Separation of these amino acids was neither achieved on conventional silical gel (without Ag impregnation) nor by addtion of buffered 5 % silver nitrate solution (pH 2.3) to the mobile phase.
Anal. Chim. Acta, 572 (2), 237-242 (2006). Presentation of a stability-indicating method for simultaneous determination of the steroidal hormones levonorgestrel and ethinyloestradiol both in bulk drug and in low-dosage oral contraceptives by HPTLC on silica gel with hexane - chloroform - methanol 4:12:1. The hRf value of levonorgestrel was 65 and of ethinyloestradiol 43. The compounds were well separated from their degradation products. Quantitative determination by absorbance measurement at 225 nm. Linearity of levonorgestrel and ethinyloestradiol was 200–800 and 40–160 ng/spot, respectively.
Phytochem. Anal. 20, 154-158 (2009). TLC of the purgative constituents of rhubarb (sennoside A and sennoside B) on silica gel with 1-propanol - ethyl acetate - water - acetic acid 40:40:30:1. After drying detection by spraying with 10 % sulfuric acid and heating. For the eastern blotting assay the developed TLC plate was dried and sprayed with isopropanol - methanol - water 1:4:16. Transfer by using a PVDF membrane sheet for further treatment.
J. Chinese Trad. Patent Med., 30 (11), 1638-1642 (2008). TLC of Shujin Huoxue capsule extracts on silica gel with 1) petroleum ether (60-90 ºC) - ethyl formate - formic acid 15:5:1; 2) cyclohexane - ethyl acetate 9:1; 3) toluene - acetone - ethanol - ammonia 16:12:1:4. Detection 1) by exposure to iodine vapor; 2) under UV 365 nm; 3) under UV 254 nm. Identification by comparison with the standards of the component drugs. Quantification of paeoniflorin by HPLC.
J. Planar Chromatogr. 22, 255-263 (2009). TLC of 25 triphenylmethane derivatives using paraffin oil-coated silica gel and acetone-water mixtures, in which the acetone content varied between 40 and 70 % in increments of 10 %. Dual retention behavior is observed for triphenylmethane derivatives in reversed phase HPTLC when the composition of acetone-water mobile phase is varied. The physicochemical and molecular properties of triphenylmethane derivatives lead to an unusual retention behavior, which was investigatd by traditional quantitative structure-retention relationship modeling and by 3D molecular modeling. Lipophilicity was found to be the most important molecular property governing the retention of triphenylmethane derivatives.
J. Chromatogr. A 1216 (42), 7102-7107 (2009). HPTLC of co-trimoxazole tablets (combination of sulfamethoxazole and trimethoprim) on silica gel with toluene – ethyl acetate – methanol 100:57:43. Detection under UV 254 nm. The hRf values were 30 and 61 for trimethoprime and sulfamethoxazole, respectively. Quantification by densitometry at UV 254 nm. Cochran's criterion test indicated homoscedasticity of variances for the calibration data. The F-tests for lack-of-fit indicated that straight lines were adequate to describe the relationship between spot areas and concentrations for each compound. Repeatability and precision (%RSD) was 1.0 and 0.8 % for sulfamethoxazole as well as 1.3 % and 1.6 % for trimethoprim, respectively. Recovery was 99.0 % and 99.7 % for sulfamethoxazole and trimethoprim, respectively.
Pharmazie 64, 104-109 (2009). TLC of christinin-A as marker and leaf extracts on silica gel with chloroform - methanol - water 13:8:2 and butanol - acetic acid - water 4:1:5 (upper phase). Detection by spraying with p-anisaldehyde reagent.
Indian Drugs 46(6), 477-482 (2009). HPTLC of extracts of Cassia auriculata, C. obtusifolia, and C. uniflora and of chrysophanol and emodin on silica gel with toluene - ethyl acetate - formic acid 10:3:1. Detection under UV 254 nm. Based on the fingerprint and by comparison with chemical markers identification of each species was possible.
