Learned J. Dali Acad. (General Issue) 8 (10), 3-6 (2009). TLC of puerarin (in extracts obtained from different parts of Radix Puerariae) on silica gel with trichloromethane – methanol – water 14:5:1. Detection under UV 254 nm. The maximum amount of puerarin was found in the bine of the drug, followed by that in the root, whereas no puerarin was found in the flower and fruit.
CBS 104 5-6 (2010). HPTLC of skin lipids (squalene, triolein, palmitic acid, 1,2-dipalmitoyl-sn-glycerol, stearyl palmitate, cholesteryl palmitate, and cholesterol) on silica gel (prewashed with methanol) first with toluene to a developing distance of 80 mm, then with n-hexane - t-butyl methyl ether - acetic acid 80:20:1 to 45 mm in a twin-trough chamber saturated for 20 min. Detection by dipping in copper(II)sulfate regent followed by heating for 30 min at 140 °C. Densitometric absorbance measurement at 350 nm. Stability of standards and samples during 3 h in solution and on the plate was good. The differences of the hRf values of 7 compounds on 3 plates was good (< 3). The precision of measurement was lowest on HPTLC LiChrospher silica gel plates (RSD of < 5 %, n=9). The linear range for all but two compounds was between 100 and 350 ng/band and correlation coefficients were > 0.9975.
IPA Convention, 2010, RA-PO 03. HPTLC of edaravone in samples of human plasma (purified by liquid-liquid extraction) on RP-18 with n-butanol - methanol - diethyl ether 1:8:1. The compound was well resolved with an hRf value of 81. Densitometric evaluation at 240 nm. The limit of detection and quantification was 25 ng and 150 ng respectively. The linearity was 600-2400 ng/band. Recovery (%) based on analysis of spiked sample was more than 65 %.
Abstract No. C-37, 61st IPC (2009). HPTLC of methanolic leaf extracts of Aloe vera (after purification with petroleum ether (60-80 °C)) on silica gel with toluene - ethyl acetate - glacial acetic acid - methanol 4:18:1:4. Under UV 254 nm six bands with hRf values of 12, 26, 34, 44, 62, and 84 were observed. These bands correspond to well known constituents of Aloe vera: aloeresin hRf 25, barbaloin hRf 33, aloe emodin hRf 43, emodin hRf 63. The bands with hRf values of 12 and 84 could not be identified. The reported finger print profiling can serve as potential technique for authentification and batch to batch consistency of herbal drugs.
E-Journal of Chemistry 6(1), 295-302 (2009). HPTLC of rofecoxib and tizanidine on silica gel (plates pre-washed with methanol and dried at 110 °C) with toluene - ethyl acetate - methanol - triethyl amine 60:30:5:1 with chamber saturation for 15 min. The hRf value of tizanidine was 49 and of rofecoxib 68. Rosiglitazone was used as internal standard. Densitometric evaluation at 235 nm. The method was linear in the range of 3.75-11.35 µg/band for rofecoxib and 0.30-0.70 µg/band for tizanidine. The recovery was 99.6-101.0 %.
Asian J. Chemistry 22(1), 27-30 (2010). HPTLC of simvastatin (in bulk and tablet dosage form) on silica gel with toluene - ethyl acetate - formic acid 10:3:1. The hRf value of simvastatin was 26. Densitometric evaluation at 242 nm. The method was linear in the range of 200-1000 ng/band.
Research Journal of Pharmaceutical, Biological and Chemical Sciences 1(4), 354-359 (2010). TLC on silica gel with toluene - methanol - triethylamine 12:6:1 with chamber saturation for 15 min. Densitometric evaluation at 290 nm. The hRf value was 23 and 67 for famotidine and domperidone, respectively. The method was found to be linear in the range of 100-500 ng/band. The recovery was 98.8 %.
Journal of Pharmacy Research 2(1), 189-195 (2009). A validated HPTLC method has been developed for simultaneous estimation of valdecoxib and tizanidine in dosage form. HPTLC on silica gel with toluene - methanol - ethyl acetate 2:2:1. The compounds were well separated as compact bands. The method was linear in the range of 10-100 ng/band for tizanidine and 100-1000 ng/band for valdecoxib. The recovery was in the range of 99.3-101.2 %. Densitometric quantification at 254 nm. The method is suitable for quality control of combined dosage form.
