Analysis of Chloramphenicol in Propolis Extract by LC/MS/MSShokuhin Eiseigaku Zasshi, 2008;49(6):399-402
A quantitative analysis method using LC/MS/MS of chloramphenicol (CAP) in propolis extract (ethanol extract) has been established.
Extraction of CAP from propolis extract was performed by adding water, followed by salting-out with sodium chloride. Through this procedure, the wax components of propolis extract could be effectively removed...
When eight samples of propolis extract products on the market were analyzed using this method, CAP was not detected (N.D.) in any of the samples.
