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.
在采用高效液相色谱法对官厅水库水华藻类细胞中的微囊藻毒素进行研究之后，又运用液相色谱 - 电喷雾电离质谱法对其展开了进一步研究。结果显示，水华藻类细胞所含的五种微囊藻毒素中，有三种为常见的微囊藻毒素 -RR、微囊藻毒素 -LR 和微囊藻毒素 -YR，其分子量分别为 1038、995 和 1045。另外两种微囊藻毒素的分子量分别为 1052 和 1009，它们分别对应微囊藻毒素 -YY 和 Mglu -LR 的分子量，不过这两种微囊藻毒素的完整鉴定仍需进一步开展。
