摘要:

采用反相高效液相色谱法同时测定了咸鸭蛋黄中的斑蝥黄和苏丹红。以乙腈-甲醇-氯仿(体积比为1∶0.5∶0.5)混合溶液提取咸鸭蛋黄中的斑蝥黄和苏丹红。提取液经减压蒸馏至近干,用乙腈定容。以乙腈-水(体积比为95∶5)为流动相,经XDB-C18色谱柱(250 mm×4.6 mm)分离,采用478 nm~520 nm~471 nm三段变波长检测,获得了较好的分离效果和较低的检测限。将该法用于咸鸭蛋黄中斑蝥黄和苏丹红的测定,苏丹红Ⅰ、苏丹红Ⅱ、苏丹红Ⅲ、苏丹红Ⅳ和斑蝥黄的回收率分别为97.34%,89.56%,90.98%,93.63%和95.15%;相对标准偏差分别为2.7%,4.3%,5.1%,4.9%和3.1%。该法简便、快速、准确。

Abstract:

A reversed-phase high performance liquid chromatographic (RP-HPLC) method for the simultaneous determination of canthaxanthin, Sudan Red Ⅰ, Sudan Red Ⅱ, Sudan Red Ⅲ and Sudan Red Ⅳ in salted duck egg yolk has been developed. These canthaxanthin and Sudan Red dyes were extracted with a mixture of acetonitrile, methanol, and chloroform (1∶0.5∶0.5, v/v). The extract was dried by a rotary evaporator. The residue was transferred to a graduated tube and diluted to 10 mL with acetonitrile. The canthaxanthin and Sudan Red dyes were separated on a XDB-C18 column (250 mm×4.6 mm), with acetonitrile-water (95∶5, v/v) as mobile phase. They were then detected at 478 nm-520 nm-471 nm at different retention times by UV/Vis spectrophotometer. The recoveries of sudan Ⅰ, sudan Ⅱ, sudan Ⅲ, sudan Ⅳ, and canthaxanthin were 97.34%,89.56%,90.98%,93.63% and 95.15% respectively. The relative standard deviations (RSDs) were 4.7%,4.3%,5.1%,4.9% and 3.1%, respectively. The method is simple, rapid and accurate.
