J. Sep. Sci. 30, 2092-2096 (2007). HPTLC of flavonoids in Bauhinia variegata, Bacopa monnieri, Centella asiatica, Ginkgo biloba, Lonicera japonica, Rosa bourboniana, Rosa brunonii, and Rosa damascena on RP-18 with two-fold development with water (5 % formic acid) – methanol 7:3 and water (5 % formic acid) – methanol 1:1 as mobile phases. Quantitative determination by absorbance measurement at 280 nm. The hRf values of apigenin (1), quercetin (2), rutin (3), luteolin (4), and quercitrin (5) were 19, 29, 34, 51, and 63, respectively. Linearity was between 150 and 800 ng/zone for (1) and (3) and between 200 and 1000 ng/zone for (2), (4) and (5). The limits of detection and quantification for (1) – (5) were 30 and 166 ng/zone, 40 and 200 ng/zone, 20 and 150 ng/zone, 40 and 200 ng/zone, and 40 and 200 ng/zone, respectively. Recovery was between 97 and 99.8% for (1) – (5).
59th Indian Pharmaceutical congress F-220, 442, (2007). HPTLC of 6-gingerol in herbal extracts on silica gel with n-hexane - ethyl acetate - ammonia 14:5:1 in a chamber saturated for 45 min. Densitometric evaluation at 254nm. The hRf value of 6-gingerol was 52. The method was linear in the range of 100 - 1200 ng/zone.
Chromatographia 66 (1-2), 95-102 (2007). HPTLC of dasatinib in the presence of its degradation products, on silica gel sheets with toluene - chloroform 7:3. Quantification by densitometry at 280 nm. The hRf value of dasatinib was 23 and selectivity regarding matrix was given. Validation of the method as per the ICH guidelines. Dasatinib was subjected to acid–alkali hydrolysis, oxidation, dry heat, wet heat and photodegradation. The drug was susceptible to acid–alkali hydrolysis and oxidation. The drug was found to be stable in neutral, wet heat, dry heat and photo-degradation conditions.
CBS 98, 2-4 (2007). HPTLC of amino-3-propan-1-ol, a degradation product of dexpanthenol, on silica gel with ethanol - water - acetic acid 16:3:1. To the mobile phase the derivatization reagent was added, i.e. 0.5 g ninhydrin were dissolved in 100 mL solvent mixture. Development in the horizontal developing chamber from both plate sides over 40 mm. Detection by heating at 105 °C for 5 min. Quantitative determination by absorbance measurement at 486 nm. The hRf value of amino-propanol was 50. The mean repeatability was 4.9 % at 5 different concentration levels. The relative standard deviation of the intermediate precision (n=9) was 5.7 %. The limit of detection and quantification was 4.5 µg/mL and 15 µg/mL, respectively (related to the application volume of 2 µL). Recovery (n=15) was 102 %.
iNDIAN dRUGs 44(8), 632 (2007). TLC, HPTLC and NMR spectroscopic methods are reported for identification and characterization of aloin isolated from Kumariasava and Aloe vera. TLC and HPTLC of chloroform extracts on silica gel with chloroform - ethyl acetate 3:1. Detection under UV 366 nm. The hRf value of aloin was 84.
59th Indian Pharmaceutical congress F-11, 392, (2007). HPTLC oleanloic acid from seeds of Achyranthes aspera on silica gel with n-hexane - ethyl acatete - acetic acid 30:201. Detection by spraying with anisaldehyde - sulphuric acid reagent. Densitometry at 530 nm for quantification of oleanolic acid. Linearity was between 200 and 1200 ng/zone. The plant tree was found to contain 0.34 % oleanloic acid. The method can be used for routine quality control.
J. Planar Chromatogr. 21, 55-59 (2008). HPTLC of glucosamine on amino phase with methanol - ethanol - 25 % ammonia 1:1:1 in a saturated chamber. Detection by heating at 160 °C for 10 min. A Tidas TLC 2010 system was used for direct spectrophotometry of the HPTLC plates. Averaged glucosamine densitograms in the wavelength range 305 to 330 nm were obtained from the spectra.
CBS 100, 10-12 (2008). HPTLC of beta ecdysone in Pfaffia glomerata extract on silica gel over 50 mm with the lower phase of chloroform - methanol - water 7:5:2 after chamber saturation for 15 min. Detection by dipping in anisaldehyde reagent (0.5 mL anisaldehyde, 10 mL acetic acid, 5 mL sulfuric aicd, and 85 mL methanol) followed by heating at 120 °C for 20 min. Quantitative determination by absorbance measurement at 432 nm. Polynomial calibration in the range of 0.04 to 0.2 µg/band (sdv 1.6 %). The evaluated extracts contained 0.8 to 1.2 % of beta ecdysone.
