【摘要】 建立香蕉中赤霉素残留量的测定方法。样品经甲醇提取,使用石油醚进行脱色,经C18固相萃取小柱净化后,使用高效液相色谱法(紫外检测器)进行测定。方法检出限为0.1 mg/kg,在0.50～10.0 mg/kg添加水平,回收率为86%～105%,相对标准偏差为2.0%～4.8%。更多还原

【Abstract】 A method for the determination of gibberellin residue in banana sample was established with high performance liquid chromatogram coupled ultraviolet detector(HPLC-UVD).Residues of gibberellin were extracted from sample with methanol.After been cleaned up,the final extract was injected into HPLC-UVD.The detection limit was 0.1 mg/kg,Precision and recovery tests were made at the spike level of 0.50~10.0 mg/kg,and the results were as follows: recoveries in the range of 86% ~105%,relative standard deviation 2.0%~4.8%.更多还原
