The extin were eluated with chloroform-rnethanol(95:5) in silica gel column. The elu were concentrated and duel. The residues were dissolvel in methanol and appliel on thin layer chromatography plate and developped with ethylacewe:igooctane:acetic acid:t-iethylamine (2fX):6:0.4:0.2). Thc€e plates ndrielandanalyby bicautography with Baciiilus subtilis (ATOD 6633), These result indicatul the detution limit was more them25 ppb. The rovey rate from egg and meat were 63% and 70%, receptivity.
