59th Indian Pharmaceutical Congress F-57, 403, (2007). HPTLC of duloxetine hydrochloride on silica gel with chloroform - methanol 4:1. Densitometric evaluation at 217nm. The hRf value of duloxetine was 45. The limit of detection and quantification was 120 and 240 ng/zone, respectively. Degradation products (acid, alkali, oxidative and thermal) were well separated from the main component. The proposed HPTLC method was routinely applied for identification and quantification of the drug in the formulation.
59th Indian Pharmaceutical congress F-37, 399, (2007). HPTLC of nebivolol and hydrochlorthiazide on silica gel with methanol - ethyl acetate - toluene - glacial acetic acid 15:25:4:1. Densitometry at 285 nm. The method was linear in the range of 150 - 350 ng/zone for nebivolol and 370 - 870 ng/zone for hydrochlorothiazide. Recovery was 99.5 %.
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, 217-219 (2008). HPTLC of puerarin on silica gel, prewashed with methanol, with ethyl acetate - methanol - distilled water 8:1:1 in a twin-trough chamber saturated for 5 min. Quantitfication by densitometry at 366 nm.
using HPLC, HPTLC and densitometry. Phytochem. Anal. 19, 550-559 (2008). HPTLC of the leaves of Lawsonia inermis L., on silica gel with ethyl acetate – formic acid – water 82:9:9 followed by drying at 110 °C for 15 min. Detection by spraying with diphenylborinic acid aminoethylester 0.5 % in ethyl acetate, followed by drying and dipping into macrogol reagent (1 g polyethylene glycol 400 in 20 mL dichloromethane). Quantitative determination by absorbance measurement at 337 nm. Chemical fingerprint was used for quality evaluation of herbal products and detection of adulteration. Comparison with an HPLC method gave comparable results.
J. Chinese Trad. Patent Med. 30 (11), 1642-1646 (2008). TLC of Yinao pill extracts on silica gel with 1) toluene - ethyl acetate 9:1; 2) benzene - ethyl acetate 3:2; 3) toluene - ethyl acetate - formic acid 28:8:1. Detection 1) by spraying with 10 % phosphomolybdic acid in ethanol and heating at 105 ºC; 2) by spraying with 10 % sulfuric acid in ethanol and heating at 105 ºC.
Abstract No. 9145, IHCB (2009). Terminalia chebula (an important constituent of Triphala, a popular ayurvedic formulation) was standardized for gallic acid content by HPTLC on silica gel with toluene - ethyl acetate - formic acid 10:10:3. The hRf value of gallic acid was 45. Quantitative determination by absorbance measurement at 254 nm. The method was linear in the range of 150-550 ng/spot. Hydroalcoholic extracts of the fruit pulp contained 10.5 mg/g gallic acid.
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.
