1) Single method for the analysis of tetracyclines on silica gel high performance thin-layer plates. J. Chromatogr. 260, 457-462 (1983). HPTLC of tetracyclines on silica plates predeveloped with a saturated aq. solution of Na EDTA with a) chloroform - methanol -5 % Na EDTA solution 65:20:5, b) isopropanol - ethyl acetate - 5 % aq Na EDTA solution 3:4:7 and c) acetone - 5 % Na EDTA solution 10:1. Detection by UV 365 nm. Quantification by scanning in dual-wavelength mode at 360/600 nm and 450/650 nm. Change of the measurement wavelength enables the determination of overlapping spots.

Two-dimensional TLC of aflatoxin M1 on silica with 1) ether - methanol - water 94:5:4.5:1.5, 2) chloroform - acetone - isopropanol 85:10:5. Detection by UV 365 nm.
J.A.O.A.C. 67, 317 (1984). TLC of aflatoxin B1 on silica with hexane - THF - ethanol 7:2:1 and of aflatoxin M1 on silica with ether - methanol - water 95:4:1. Detection by UV 365 nm. Fluorometry. Repeatability 2-13 %
J. Pharm. Biomed. Anal. 9, 717-723 (1991). TLC of antibiotic metacycline and its major impurities oxytetracycline, 4-epimetacycline, doxycycline, 2-acetyl-2-decarboxamidometacycline and 6-epidoxycycline on silica pretreated with EDTA/sodium hydroxide with dichloromethane – methanol water 58:35:7. Detection under UV; quantification by densitometry at 254 nm.
Sz. Nyiredy, A. Kakuk (eds.): Planar Chromatography 2000, Lillafüred, Hungary, 24-26 June 2000, Res. Inst. for Med. Plants, p. 143-148. Validated methods: HPTLC of dexamethasone sodium phosphate and neomycin sulfate on silica gel with concentration zone with chloroform - 1-propanol - NH3 1:3:2. HPTLC of ketoconazole on silica gel with n-hexane - acetone 4:1. HPTLC of coenzyme Q10 on silica gel with n-hexane - chloroform - methanol 5:4:1. Quantitation by polynomial regression at 246 nm for dexamethasone sodium phosphate, at 230 nm for ketoconazole, at 275 nm for coenzyme Q10 and after derivatization with ninhydrin solution at 500 nm for neomycin. Precision is found to be between 0,8-2,68 %.
Food Addit. Contam. 24, 351-359 (2007). Inter-laboratory validation of the analytical method (published in the SIMBAG-FEED report 4.6) based on TLC coupled to bio-autography for the detection of tylosin, spiramycin and virginiamycin in feeding-stuffs for poultry, pig, cattle and calf. The detection limit of spiramycin was 2 mg/kg and the method has a target concentration of 1 mg/kg for tylosin and virginiamycin. The method showed high specificity and offers the possibility for screening before LC/MS analysis.
J. Planar Chromatogr. 24, 30-34 (2011). TLC of ceftriaxone sodium on RP-18 with 15 % ammonium acetate buffer (pH 6.2) - methanol - acetonitrile 48:2:1 after saturation of the chamber for 20 min. Detection under UV light at 254 nm. Quantitative determination by densitometry in absorbance mode at 302 nm as well as by use of TLC-image analysis. Linearity was between 1-8 µg/zone. LOD and LOQ were 228 and 759 ng/zone, respectively. The hRf value of ceftriaxone sodium was 58.
J. Liq. Chromatogr. Relat. Technol. 37, 1805-1818 (2014). HPTLC of azithromycin dehydrate (1) and cefixime trihydrate (2) on silica gel with methanol – ethyl acetate – toluene – ammonia (30 %) 45:35:20:4. Quantitative determination (A) by absorbance measurement at 366 nm or (B) after spraying with stannic chloride reagent (40 mL chloroform and 40 mL glacial acetic acid were mixed and 5 mL of stannic chloride was slowly added) or (C) ethanolic sulfuric acid (20 mL of concentrated sulfuric acid in 80 mL of ethanol) followed by absorbance measurement at 450 nm for (B) and (C). The hRF values for (1) and (2) were 80 and 27 for (A) and (B) and 67 and 30 for (C). Due to concentrated sulfuric acid, (C) showed a slight change in hRF. Linearity for (1) was in the range of 1000-5000 ng/zone (A), 1500-5000 ng/zone (B) and 1000-6000 ng/zone (C) and for (2) was 400-2000 ng/zone (A), 1600-4000 ng/zone (B) and 800-2400 ng/zone (C). The intermediate/inter-day/intra-day precision was below 2 % (n=3). The LOD and LOQ for (1) was 85 and 257 ng/zone (A), 119 and 360 ng/zone (B) and 39 and 119 ng/zone (C) and for (2) it was 36 and 110 ng/zone (A), 194 and 588 ng/zone (B) and 69 and 208 ng/zone (C), respectively. Recovery was in the range of 98.2-102.4 % for both (1) and (2).
