microcystin-ll and 4-hydroxyphenyllactic-acid

Microcystins in the algal cells collected from the water bloom of the Guanting Reservoir were further investigated by LC-ESI/MS after they were studied by the method of HPLC. The results show that three of five microcystins contained in the algal cells of the blooms are frequent Microcystin-RR, Microcystin-LR and Microcystin-YR, whose molecular weights are 1038, 995 and 1045 respectively. The molecular weights of the other two microcystins are 1052 and 1009, which are corresponding to the molecular weights of Microcystin-YY and Mglu-LR respectively, however the complete identification of both MCs have to be carried out further.
