Mass Spectrometric Conf rmation of the Af atoxins

The aflatoxins may be confirmed by negative ion chemical ionization-mass spectrometry. The aflatoxin is first purified using preparative TLC. The entire extract is applied along the origin line of a TLC

plate which is developed using chloroform-acetone (9 : 1 v/v). After drying, the silica gel is scraped from a band containing the aflatoxin B1. If the silica gel is scraped into a sintered glass funnel the aflatoxin can be eluted with chloroform-methanol (2 : 1 v/v). After evaporation and re-dissolving in acetone, the aflatoxin can be introduced into the inlet probe of the mass spectrometer and spectra of sample and standard aflatoxin compared.
