      Different chromatographic methods for the simultaneous
      determination of vitamin E and vinpocetine in their combined dosage form and in the presence of the alkaline-induced degradation product of vinpocetine
      M.M. ABDELRAHMAN, N.S. ADBELWAHAB, F.M. SALAMA, A.B. AHMED* (*Analytical Chemistry Department, Faculty of Pharmacy, Beni-Suef University, Beni-Suef, Egypt, amal.badawy@nub.edu.eg)

      J. Planar Chromatogr. 29, 372-379 (2016). HPTLC of vitamin E (1) and vinpocetine (2) in its alkaline-induced degradation product (3) on silica gel with methanol – chloroform – ethyl acetate – glacial acetic acid – ammonia 60:20:20:5:1. Quantitative determination by absorbance measurement at 235 nm. The hRF values for (1) to (3) were 81, 62 and 41, respectively. Linearities were between 0.2-2 µg/zone for (1), 0.1-1.5 µg/zone for (2) and 0.1-1 µg/zone for (3). The intermediate precisions were below 0.7 % (n=3). The LODs and LOQs were 67 and 198 ng/zone for (1), 32 and 98 ng/zone for (2) and 29 and 87 ng/zone for (3). Average recoveries were 99.6 % for (1), 100.0 % for (2) and 99.9 % for (3). The results were statistically compared with those obtained by a HPLC method and no significant differences were found.

Linearity was between 100 and 300 ng/zone for (1) and 50 and 150 ng/zone for (2). LOD and LOQ were 38 and 110 ng/zone for (1) and 16 and 50 ng/zone for (2). The intermediate precision was <2 % (n=6). Recovery ranged from 98.8 to 101.2 % for both (1) and (2).
