J. of Pharm. Biomed. Anal. 44 (3), 812-817 (2007). HPTLC of extracts of Notopterygium incisum Ting ex H.T. Chang (or Notopterygium forbesii Boiss) root and rhizome, and marker compounds isoimperatorin, notopterol and bergapten. The authentication of rhizoma et radix Notopterygii was achieved by comparing the colors and Rf values of the bands in TLC fingerprints with those of the marker compounds. The HPLC fingerprints of 16 batches of herbal samples from different regions of China showed similar chromatographic patterns. Five peaks were selected as characteristic peaks, and three of these were identified by using LC-MS-MS techniques.
J. Planar Chromatogr. 21, 125-128 (2008). TLC of a racemic mixture of diastereomeric salts formed by pipecoloxylidides (pipecoloxylidide, mepivacaine, N-ethylpipecoloxylidide, ropivacaine, bupivacaine) with O,O’-dibenzoyl-2R,3R-tartaric acid on silica gel with 1-butanol - glacial acetic acid - water 12:3:5 after chamber saturation for 2 h at 25 °C. TLC was also performed using 2-propanol, ethanol, and methanol instead of 1-butanol. Detection by spraying with 1 N potassium permanganate solution and Dragendorff reagent. Evaluation under UV light.
J. Liq. Chromatogr. Relat. Technol. 31, 250-262 (2008). Analytical and preparative TLC of saponins (arganine A, C, D, and tieghemelin in the seed of Tieghemella heckelii) on silica gel with chloroform - methanol - 0.5 % TFA 12:8:1. Detection by spraying with a solution of 2 % cerium sulfate in 5.6 % sulfuric acid.
Anal. Chim. Acta 582(1), 75 - 82 (2007). TLC of moxifloxacin both as a bulk drug and from pharmaceutical formulation on silica gel with n-propanol - ethanol - 6M ammonia 4:1:2. Quantification by absorbance measurement at 298 nm. The hRf value of moxifloxacin was 58. Linearity was in the range of 100–800 ng/spot. LOD and LOQ were 3.9 and 11.8 ng/spot, respectively. In stability studies (acid and alkali hydrolysis, oxidation, dry heat, wet heat, photodegradation) degradation products were well resolved from the standard drug. The method was suitable to investigate the kinetics of the acidic and alkaline degradation processes at different temperatures.
Science & Culture Jan.-Feb., 22-30 (2008). Isolation and identification of some unique chemical compounds is reported using chemical, chromatographic and spectroscopic methods such as GC-MS, HPTLC and HPLC. The presence of bio-organic molecules such as oxygenated dibenzo-a-pyrones (DBPs), their amino acyl conjugates (DCPs) and polyphenyl benzoquinones (PBQs) was observed in all the four samples of meteorites. HPTLC on silica gel with 1) n-butanol - acetone - acetic acid - water 7:7:2:4 for amino acids, detection with ninhydrine reagent and absorbance measurement at 610 nm; 2) n-butanol - acetic acid - water 3:1:2 for sugars, detection with p-anisidine reagent and absorbance measurement at 380 nm; 3) chloroform - methanol 9:1 for DBPs and absorbance measurement at 240 nm and 360 nm.
J. Planar Chromatogr. 21, 295-298 (2008). HPTLC of a test compound [1-(4-hydroxyphenylazo)-2-napthol] on RP-18 (prewashed with methanol) with acetonitrile - water - buffer (pH 4.8) in the desired volume ratio in a horizontal developing chamber saturated for 15 min. Quantitative determination by absorbance measurement with a diode array TLC scanner. The retention-composition relationship obtained with TLC is similar to those of pressurized planar electrochromatography and HPLC in the modifier concentration range 60-80 % but deviates substantially at higher modifier concentrations.
J. Planar Chromatogr. 22, 65-71 (2009). Presentation of two simple and rapid HPTLC methods for early detection of the effects of herbicides using two different groups of plant biomarkers, which were developed as field tests (Herbicide Weed Response test - HWR-Test). Phytochemical changes can be detected before any morphological changes are visible on the plants. These changes are defined as biomarkers and can be detected by HPTLC-screening. After overall identification of the phytochemical biomarker pattern, two different biomarker groups, carbohydrates and amino acids, were detected using modified reagents for color reactions. Evaluation under daylight and videodensitometric analysis of digital images by VideoScan software. The screening method was previously described [H. W. Ravn, M. Hjorth, L. Lauridsen, P. Kudsk, S. K. Mathiassen, L. Mondolot, Bull. Environ. Contam. Toxicol. 75, 236-245 (2005)].
Phytochem. Anal. 20, 177-190 (2009). TLC and HPTLC of polyphenols (tellimagrandins I and II, rugosins A, B, D and E and other) in commercially available products of meadowsweet (Filipendula ulmaria) and dog rose (Rosa canina) on silica gel, LiChrospher Si 60, RP-18 and amino phase with tetrahydrofuran - acetonitrile - water 3:1:1, of tannins on amino phase with acetone - formic acid 3:1, of flavonols with acetone - formic acid 17:3, of tannins with diisopropyl ether - acetone - formic acid - water 4:4:1:1, and of flavonols with diisopropyl ether - acetone - formic acid - water 5:3:1:1. Detection of polyphenolic compounds under UV light at 254 and 366 nm before and after spraying with natural products reagent followed by polyethylene glycol reagent. Detection in white light after spraying with 1 % iron(III) chloride (for tannins and phenolic acids), vanillin-hydrochloric acid (flavonols) or bis-diazotised sulfanilamide (for all polyphenols). Quantitative determination of polyphenol contents by HPLC with UV detection. Meadowsweet flowers and rose hips with seeds yielded 55.5-124.8 and 0.4-1.3 mg/g of ellagitannins, respectively. The sum of detected polyphenols was 83.9-165.7 mg/g for Filipendulae ulmariae flos and 1.2-2.7 mg/g for Rosae pseudo-fructus cum fructibus.
