Analysis of crude taxol sample by LC-MS spectrometry

Fang Dongsheng(Fujiang Institute of Microbiology,Fuzhou,350007)  
objective:Crude taxol sample was analyzed by using liquid chromatorgraphy-electrospray ionization massspectrometry.Methods:column:Nucleosil C18(250×4.6mm,5um);mobile phase:CH3OH-H2O(65/35,V/V);flow rate:1m1/min;wavelength:227nm;temperature:40℃;20% of the exit from liquid chromatorgraphy was pumped into the iontrap inside,the mass spectrometry and the mass spectral of components of the sample was analyzed.Results:the crudetaxol sample contains baccatin Ⅲ,10-deacetylbaccatin Ⅲ,taxol,cephalomannine and dihydrocephalomannine according toLC/MS result.Conclusion:LC-MS method is a sensitive,rapid and credible method for the analysis of crude taxol.Sample.
