The linear range was 100-1000 ng/band for all three compounds, and the correlation coefficients r were 0.97, 0.94, and 0.95, respectively. LOQ were 123, 95, and 61 ng/band, respectively, and the respective LOD were 37, 37, and 18 ng/band.
J. Planar Chromatogr. 23, 396-399 (2010). TLC of 8 newly synthesized N-phenyltrichloroacetamides on RP-18 W with micellar-organic solutions composed of 0.02, 0.04, or 0.06 M Brij 35 (2-dodecoxyethanol, a nonionic surfactant) and tetrahydrofuran 4:1 in saturated sandwich chambers. Detection under UV 254 nm. According to the results obtained from the OPLC studies, especially log km values are excellent descriptors of the lipophilicity of the compounds.
J. Planar Chromatogr. 24, 236-241 (2011). HPTLC of levodopa (LEV), carbidopa CAR), and entacapone (ENT) in a combined dosage form on RP-18 (prewashed with methanol) with acetonitrile - n-butanol - water - triethylamine 1:19:2:0.002, pH adjusted to 3.6 with phosphoric acid, in a twin-trough chamber saturated with mobile phase for 25 min. Quantitative determination by densitometry in absorbance mode at 282 nm. The hRf values were 46, 64, and 87 for LEV, CAR, and ENT, respectively. Linearity was between 300-1500 ng/zone for LEV, 200-1000 ng/zone for CAR, and 200-2000 ng/zone for ENT. The intra-day and inter-day precision was below 1.8 % RSD for all drugs. The recovery for LEV, CAR, and ENT (n = 3) was between 101.0 and 102.4 %.
