| 中文摘要 |
| 在利用高效液相色谱方法研究的基础上,采用液相色谱-电喷雾质谱(LC-ESI/MS)方法对相同的藻毒素样品进行了进一步的定性研究.结果表明,官厅水库微囊藻产生的5种微囊藻毒素中3种分别是常见的Microcystin-RR,Microcystin-LR和Microcystin-YR,分子量分别为1 038,995和1 045.另外2种分子量分别为1 052和1 009,分别与Microcystin-YY和Mglu-LR的分子量相同,但完全的验证工作还有待更深入的研究. |
| 英文摘要 |
| 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 1 038,995 and 1 045 respectively.The molecular weights of the other two microcystins are 1?052 and 1?009,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. |
