Indian Drugs 41 (3), 160-164 (2004). Combinations of ofloxacin and tinidazole (1:3) are available as tablet dosage forms. Stability indicating HPTLC of ofloxacin and tinidazole on silica gel with dioxan - ethyl acetate - toluene - acetic acid - water 5.5:5:3.2:2:2 . Quantification by absorbance measurement at 307 nm. The Rf value of ofloxacin and tinidazole was found to be 0.12 and 0.85 respectively. Recovery was 99.85 % and 99.45 % for ofloxacin and tinidazole respectively. The proposed method was quantitatively evaluated in terms of calibration of concentration range, stability, and accuracy. It can be adopted for routine analysis of the formulation.
Indian Drugs 41 (5), 300-302 (2004). Validated HPTLC method for the estimation of stavudine in capsules on silica gel with toluene - methanol 3:1. Quantitative determination by absorbance measurement at 270 nm. The linearity range of stavudine was 1.4 µg to 3.7 µg. The amount of stavudine estimated was 40.08 mg and 40.01 mg (calculated by peak height and peak area respecively) in the average weight capsule. Recovery was 99.67 % and 99.26 % calculated by peak height and peak area respectively. The proposed method is accurate, precise, selective, and reproducible and can be used for the routine analysis of stavudine.
J. Planar Chromatogr. 17, 264-274 (2004). HPTLC of zidovudine (3’-azido-3’-deoxythymidine) and degradation products on silica gel with toluene - carbon tetrachloride - methanol - acetone 35:35:20:1. Quantitative determination by absorbance measurement at 270 nm. The method was validated for precision, robustness, and recovery. Limits of detection was 20 ng per spot, limit of quantitation 40 ng.
IPC 56th 2004, Abstract No. GP-15. Stability indicating HPTLC determination of ondansetron in solid oral dosage forms on silica gel with chloroform - methanol 4:1. Quantitative determination by scanning at 310 nm. The Rf value was 0.62 - 0.64, linearity was 40 - 120 ng. The average recovery was 100.01 %. The method was found suitable for routine analysis of formulations containing ondansetron.
Abstract CP-53, IPC (2005). HPTLC of andrographolide and wedelolactones in several market samples on silica gel with toluene - acetone - formic acid 9:6:1. Quantitative determination by absorbance measurement at 254 nm. The hRf value of andrographolide was 52 and of wedelolactone 58. Linearity was obtained between 200-400 ng/spot and 120-200 ng/spot respectively with recovery rates of 98.1-106.7 %. A complex coumarin from Eclipta alba was used as marker.
J. Planar Chromatogr. 18, 240-243 (2005). TLC of twenty-one N-benzyl-2-azaspiro[4.4]nonane- and [4.5]decane-1,3-dione derivatives on RP-18 with a mixture of n-propanol and TRIS buffer (pH 7.0) in a chamber saturated for 30 min. Detection under UV light at 254 nm. Examination of chromatographic behavior revealed a linear correlation between RM values and the concentraton of n-propanol in the mobile phase.
J. Planar Chromatogr. 18, 207-211 (2005). HPTLC of rifampicin and isoniazid on silica gel (prewashed with methanol) in a horizontal chamber with ethyl acetate - methanol - acetone - acetic acid 5:2:2:1 after pre-saturation for 30 min. Densitometric evaluation by absorbance measurement at 345 nm for rifampicin and at 270 nm for isoniazid. For isoniazid and rifampicin CV was 0.42 and 0.16 %, relative standard error 0.01 and 0.13 %, and recovery 98.9 and 102.5 %, respectively.
J. Sep. Sci. 28 (6), 575-580 (2005). HPTLC of pentoxifylline and related substances, impurities of reaction partners and side reaction products, on LiChrospher RP18 with acetone - chloroform - toluene - dioxane 2:2:1:1. Quantitative determination at 275 nm. Linearity (r2= 0.997), recovery (86.5-115.5 %) and determination limit (0.1-0.6 %) were evaluated and found to be satisfactory. This method enables monitoring of the synthesis as well as purity control of pentoxifylline-containing raw materials and pharmaceuticals.
