Vitamin D3 was found interference with other fat soluble vitamins (especially vitamin A and E) that are
commonly present with vitamin D, in Serum & pharmaceutical preparation.
In the present study, a rapid, simple and economical reversed phase-HPLC procedure has been fixed
optimization of condition and developed for the separation and determination of vitamin D3 in mixture standard
of Vitamin D3and Vitamin A.
Anew method were developed in HPLC ,based method with a UV detector by examining various conditions
including mobile phase, flow rate, volume inject and temperature, we have also proposed a very simple method
of isolation of these vitamins. The vitamins were separated isocratically on a Knauer C18 column (250×4.6mm,
5μm particle size) with a mobile phase consisting of isocratic acetonitrile and methanol (75:25, v/v) operated at
40ºC with retention times less than 10 min. and the detection limit of our developed HPLC method is 0.01μg/ml.
The eluted vitamins were identified and monitored on a UV-Detector at 265 nm with optimum flow rate 1.5
mL/min and 50μL Injection volume. The linearity of the method was excellent (r2 > 0.999), over the concentration range
of 10-200ng/ml.
