MG：孔雀石绿
LMG：隐色孔雀绿
Robustness of the method,which was apparently omitted in many method descriptions so far,was investigated.For that reason,chromatographic parameters of MG and LMG were determined on three different HPLC columns.Each HPLC column was examined with three mobile phase batches (Table 2).All chromatograms were similar,with best analytical performance for the determination of LMG.Furthermore ,samples were processed over different SPE-columns from different suppliers,or with different batch numbers from the same supplier (Table 3).All batches aromatic sulfonic acid type SPE columns obtained from J.T.Baker gave acceptable recoveries,as well as the SCX cartridges purchased from IST and Varian (Bond Elut).The other columns gave rise to unsatisfactory recovery results.
In the control of illegal veterinary use of the drug,stored aquatic products may have to be sampled.Alternatively,samples may have to be stored until analysis.Such conditions may affect the final level in the laboratory sample.Stability of MG and LMG during storage at 14 8C (for 1,2 and 4 days) and at –20 °C (for 1,2 and 6 months) was therefore investigated (Tables 6 and 7).Whereas degradation of MG residues was less than 20% within 6 months at -20°C,residues were apparently very unstable at +4°C,as only approximately 60% MG and LMG was recovered after 4 days.Freeze–thaw cycles also affected stability of the residues considerably (Table 8)
The described HPLC method has been furnished with numerous data,which is scarcely given in other public method presentations,showing its ability to detect MG in several fish species.The collected data demonstrate that the sample processing and HPLC analysis,backed-up by LC–MS–MS analysis when necessary,is amenable in control and inspection programs to secure food free from this veterinary drug.

摘 要:从湖南小溪自然保护区采中分离出XX-6菌株,用静置开放式培养法研究碳源、氮源、金属离子对该菌降解孔雀石绿的影响.结果表明,菌株脱色最适合降解条件为醋酸钠12g/L,硝酸氨0.8g/L,盐度小于16g/L,在上述各培养条件下,对浓度为100mg/L不灭菌的孔雀石绿溶液静止培养5d,脱色率达90%以上.因此,该菌对处理印染废水具有较好的应用潜力.
