中文摘要 | 為同時分析飼料內卡巴得、歐來金德、富來頓、乃挫夫喃頓及乃託文,利用C₈矽膠層析管在梯度分析條件下,可得完全分離之層析圖。梯度分析主要以每min5% acetonitrile之線性梯度。五種飼料添加物檢量線之相關係數(Y)均在0.999以上且相對標準偏差0.3%以內,僅5ppm乃託文大些(6.7%)。飼料先加水處理後,以95% dimethylformamide 於室溫中過夜萃取,再通過三氧化二鋁管柱。低濃度飼料回收率分別為102.0, 94.6, 97.4, 110.6及66.0%,高濃度則為114.0, 99.1, 109.9及62.7%。 |
英文摘要 | A high-performance liquid chromatography with gradient programming method was developed to determine the amount of carbadox (CBX), olaquindox (OLQ), furazolidone (FZ), nitrofurazone (NF), and nitrovin (NTV) in feed simultaneously. Complete separation of the drugs was obtained using a C₈ silica gel column with gradients of acetonitrile as mobile phase. The mobile phase used an acetonitrile gradient with an initial hold time of 1 min at 0% acetonitrile, followed by an increase to 50% acetonitrile over 10 min. The correlation coefficients (r) for calibration curves of the five feed additives were greater than 0.999. The relative standard deviations (RSDs) of peak areas from four injections for these drugs at three concentrations were less than 3.0%, although the RSD for NTV at 5 ppm was somewhat large (6.7%). The medicated feeds were extracted by pretreating with water, extracted with 95% dimethylformamide overnight at room temperature, and cleaned up on a column of alumina oxide. Recoveries of CBX, OLQ, FZ, NF, and NTV from low level spiked feed were 102.0, 94.6, 97.4, 110.6, and 66.0% respectively, and from high level spiked feed, they were 114.09, 99.1, 97.3, 109.9, and 62.7%, respectively. |
