Indian Drugs 42 (6), 345-352 (2005). TLC fingerprint identification of methanolic extracts of Adhatoda vasica, Lawsonia inermis and Alkanna tinctoria, on silica gel. For Lawsonia inermis and Alkanna tinctoria the developing solvent toluene - acetone - acetic acid 90:10:1 was used, and for Adhatoda vasica n-hexane - acetone - diethyl ether 3:1:1 for. Detection of alkannin by spraying with 10 % methanolic KOH.
Chromatographia 64 (7-8), 423-427 (2006). TLC of six polyamines (ornithine, citrulline, putrescine, cadaverine, spermidine and spermine) on calcium sulfate (CaSO4) and silica gel with 11 different mobile phases, using methanol as the solvent to enhance selectivity and produce differential Rf values. On CaSO4 better separation was achieved than on silica gel, no derivatization is needed, and development time is about 1/3 shorter. Quantitative determination by absorbance measurement at 550 nm after extracting substances from the plates and eluting from the coating material. Limit of detection (LOD) was 750 ng, limit of quantification (LOQ) was 1880 ng. Quantitative separation of underivatized polyamines in spiked human urine samples.
J. Sep. Sci. 30, 708-712 (2007). HPTLC of icariin in the aerial part of Epimedium koreanum Nakai on silica gel with ethyl acetate – glacial acetic acid – formic acid – water 10:1:1:2. Quantitative determination by absorbance measurement at 270 nm. The LOD and LOQ for icariin were 66 and 215 ng/band, respectively. Results did not show statistical significance between HPLC and HPTLC.
59th Indian Pharmaceutical congress C-305, 297, (2007). Phytoconstituents of mature and immature tubers of Ipomoea mauritiana (methanolic and aqueous extracts) have been studied. HPTLC on silica gel with chloroform - methanol - formic acid 6:3:1. Detection by spraying with vanilin - sulphuric acid reagent. Densitometric evaluation at 365 nm. Mature tubers were found to contain higher concentration of phytoconstiuents than immature tubers.
Indian Drugs 44 (12), 937-944 (2007). HPTLC of methanolic and ethyl acetate extracts of Sesamum indicum root on silica gel with ethyl acetate - n-hexane 1:9. Densitometric evaluation at 549 nm. The red zones were isolated by preparative TLC and identified by IR as 1,4 naphthoquinone derivatives.
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.
60th Indian Pharmaceutical Congress PA-215 (2008). HPTLC of ranitidine HCl and domperidone in combined dosage form on silica gel with ethyl acetate - methanol - ammonia 100:10:1 in a twin trough chamber saturated for 10 min. Quantitative determination by absorbance measurement at 285 nm. The method was linear in the range of 100-500 ng/µL for both compounds with a recovery of 102.5-100.8 %.
Abstract No. F-10, 61st IPC (2009). HPTLC of Embella ribes Churna formulation on silica gel with chloroform - ethyl acetate - formic acid 5:4:1 in a twin trough chamber. Densitometric measurement of embelin at 291 nm. The method was linear in the range of 600-1800 ng/band with recovery value of 99.1-101.2 %. The formulation was also analyzed by HPLC and results were found to be comparable.
