Determination of Voglibose in Pharmaceutical Preparation by Gas Chromatography

Voglibose is a new antidiabetic agent currently being developed by the research and development division of Takeda chemical industries Ltd. In japan. Basic research for the determination of oglibose in pharmaceutical preparation by gas chromatography. This method utilizes voglibose to give its acyl compound with acetyl anhydride in pyridine solution. The calibration curve for rvoglibose was linear over the concentration range of 0.08~0.32 μg/μl with correlation coefficient of 0.996. The detection limit for voglibose was 0.016 μg/μl and the result of recovery test was 101.6% with relative standard deviation of 2.0% by standard addition method.
