Br. using gymnestrogenin as reference. Indian J. Pharm. Sci. 66 (2), 242-244 (2004). HPTLC of gymnestrogenin in Gymnema sylvestre on silica gel with chloroform - methanol 9:1. Quantitative determination by absorbance measurement at 293 nm. Linearity was in the range of 4-10 µg. A gymnestrogenin content of 1.11 % was found in the test sample. Average percentage recovery was 99.1 ±0.27. The proposed method is precise and sensitive and can be used for detection, monitoring, and quantification of gymnestrogenin in Gymnema sylvestre.
with and without red heartwood. J. Planar Chromatogr. 17, 350-354 (2004). TLC of (+)-catechin and (-)-epicatechin on silica gel with diisopropyl ether - formic acid 9:1. Detection by spraying with vanillin-sulfuric acid reagent and heating at 120 °C for 5 min. Quantitative determination by absorbance measurement at 513 nm.
J. Planar Chromatogr. 17, 375-378 (2004). HPTLC of parthenolide and extracts of feverfew capsules on silica gel with ethyl acetate - n-hexane 3:2 in glass chambers presaturated for 30 min. Detection by dipping in p-anisaldehyde reagent and heating at 105 °C for 5 min, followed by immediate densitometric scanning at 543 nm. The method is precise with CV < 5%; calibration recovery of 101.12 +/- 4.11 % and overall accuracy of 101.14 +/- 4.47 %. The levels of parthenolide in the products analyzed ranged from 0.03 to 0.24 %.
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. CP-32. A stability indicating HPTLC method has been developed for the analysis of solid dosage forms containing beta-carotene. HPTLC of beta-carotene on silica gel with petrol ether (40-60 °C) - methanol - toluene 4:8:1. Rf value of beta-carotene was 0.65-0.70. Quantification by densitometric evaluation at 460 nm. The method was validated for accuracy, precision, linearity, and stability, and can be adopted for routine analysis of beta-carotene in formulations.
J. Planar Chromatogr. 18, 73-77 (2005). HPTLC of isoflavonoids (puerarin, 3’-methoxypuerarin, daidzin, and daidzein) from Kudzu samples (a perennial leguminous plant of the genus Pueraria) on silica gel with chloroform - methanol - ethyl acetate- water 81:94:260:15. Quantitative determination by absorbance measurement at 254 nm. Repeatability and accuracy of HPLC compared with HPTLC are better, but separation of isoflavonoids by HPLC is time consuming and difficult. HPTLC is simple and rapid without tedious isolation of isoflavonoids. Separation and quantification of isoflavonoids from stem and leaf samples of kudzu is only achieved by HPTLC.
J. AOAC Int. 88, 1555-1561 (2005). HPTLC of chloramphenicol on silica gel in a horizontal developing chamber (36 applications per plate) using n-hexane -ethyl acetate 7:13. Quantitative determination by absorbance measurement at 280 nm. Mean recovery was 95.8 %, and the coefficient of variation was 5.8 %. The detection limit was 3 ng, and the quantitation limit 10 ng.
J. Planar Chromatogr. 18, 377-379 (2005). HPTLC of 2-azaanthraquinone from plant extracts on silica gel with toluene - ethyl acetate - methanol 40:9:1. Quantitative determination by absorbance measurement at 310 nm. Calibration was linear in the range of 10-100 µg/mL. The method was repeatable and precise with RSD between 0.98 and 1.59 % intra-day and between 3.41 and 5.56 % inter-day. Limits of detection and quantification were 3 and 6 µg/mL.
