Abstract:
A simple and cost-effective method for isolating and assaying microcystins, cyanobacterial toxins, by C-18 cartridges, DEAE-cellulose (DE-52) chromatography, and a mustard (Sinapis alba L.) plant seedling test is described. The procedure results in a purity of up to 95-97% microcystin without the need for an HPLC system and justifies the use of the S. alba L. seedling test in the quantitative assessment of the toxin with an IC50 of 3 micrograms ml-1 instead of the mouse intraperitoneal test.
