Solanum species used as ‘Brihati’ and its market samples using a validated high-performance thin-layer chromatography method
J. Planar Chromatogr. 31, 421-428 (2018). HPTLC of solamargine in Solanum species on silica gel with dichloromethane ‒ methanol ‒ 2.5% aqueous ammonia 75:25:2. Detection by dipping into anisaldehyde sulfuric acid reagent, followed by heating at 110 °C. Quantitative determination by absorbance measurement at 540 nm. The hRF value for solamargine was 15. Linearity was between 25 and 300 ng/zone. LOD and LOQ were 1 and 4 ng/zone. The intermediate precision was <2 % (n=3). Average recovery was 101.2 %.
J. Planar Chromatogr. 31, 489-495 (2018). HPTLC of abacavir sulfate (1), lamivudine hydrochloride (2), and dolutegravir sodium (3) on silica gel with ethyl acetate ‒ ethanol ‒ acetone ‒ ammonia 2239:370:250:75. A factorial design was utilized to aid in method development and optimization. Quantitative determination by absorbance measurement at 267 nm. The hRF values for (1) to (3) were 65, 34 and 26, respectively. Linearity ranged between 4.8-14.4 μg/zone for (1), 2.4-7.2 μg/zone for (2) and 0.4-1.2 μg/zone for (3). LOD and LOQ were 997 ng/zone and 3022 ng/zone for (1), 254 ng/zone and 771 ng/zone for (2), and 100 ng/zone and 304 ng/zone for (3), respectively. The intermediate precision was <2 % (n=3). Recoveries were found in the range of 98.1–101.0 % for (1), 98.3–100.00 % for (2), and 98.5–101.3 % for (3), respectively._x000D_
