      J. Planar Chromatogr. 26, 427-434 (2013). HPTLC of oseltamivir (1) in pharmaceuticals counterfeited with ascorbic acid (2) on silica gel with methanol - water 3:2 +1 drop ammonia. Quantitative determination by absorbance measurement at 254 nm. The hRf values for (1) and (2) were 70 and 83, respectively. Linearity was between 5 and 14 µg/zone. LOD and LOQ were 2 and 5 µg/zone. Average recovery (by standard addition) was found to be 100.6 %. Intermediate intra- and inter-day precision was below 1.6 %. Comparing with colorimetric method, HPTLC method provided advantages in terms of speed, lower cost, and environmental protection without sacrificing accuracy.
