该文以富硒堇叶碎米荠为研究对象,通过酶解法提取其中的硒化合物,采用高效液相色谱-电感耦合等离子质谱(HPLC-ICP-MS)定量分析已知的硒化合物;对于未知的硒化合物,将酶解液经3 kDa超滤离心管浓缩除杂、冻干后,用初始流动相复溶,选取Kinetex F5超高效液相五氟苯基柱(100 mm × 2.1 mm,2.6 μm),以0.1%(体积分数)甲酸-水溶液和0.1%(体积分数)甲酸-乙腈溶液为流动相进行梯度洗脱,通过超高效液相色谱-电喷雾电离源高分辨串联质谱(UPLC-ESI-Triple TOF MS),利用硒独特的同位素模式、一级质谱(TOF MS)和二级质谱(TOF MS/MS)进行筛选与鉴定。结果表明:HPLC-ICP-MS定量分析了堇叶碎米荠中的5种硒化合物,分别为硒代胱氨酸(SeCys,2,)、甲基硒代半胱氨酸(MeSeCys)、硒代蛋氨酸(SeMet)、四价硒[Se(Ⅳ)]、六价硒[Se(Ⅵ)];UPLC-ESI-Triple TOF MS鉴定了其他15种硒化合物,包括7种已报道和8种未报道的硒化合物,并提出了C,4,H,7,NO,2,Se、C,5,H,8,O,2,Se和C,7,H,9,NO,2,Se 3种未报道硒化合物的结构。
In this article,selenium(Se) compounds were extracted from Se-enriched ,Cardamine Violifolia(C. Violifolia), by enzymolysis method,and the known Se species were determined by high performance liquid chromatography-inductively coupled plasma mass spectrometry(HPLC-ICP-MS).As for the identification of unkown Se compounds,the enzymatic hydrolysate was firstly concentrated by removing impurities with a 3 kDa ultrafiltration centrifuge tube,then freeze-dried,and finally suspended in the initial mobile phase.A Kinetex F5 column(100 mm × 2.1 mm,2.6 μm) was selected for gradient elution.Mobile phases A and B were water and acetonitrile both prepared with 0.1%(volume fraction) formic acid.The unknown Se compounds were screened and identified by ultrahigh performance liquid chromatography-electrospray ionization high resolution tandem mass spectrometry(UPLC-ESI-Triple TOF MS)using unique isotope patterns,TOF MS and TOF MS/MS.The results showed that five Se species in, C. Violifolia, were determined by HPLC-ICP-MS,namely selenocysteine(SeCys,2,),methylselenocysteine(MeSeCys),selenomethionine(SeMet),selenite[Se(Ⅳ)] and selenate[Se(Ⅵ)].15 other Se compounds,including 7 reported and 8 unreported Se compounds,were identified by UPLC-ESI-Triple TOF MS.The structural formula of three unreported Se compounds,C,4,H,7,NO,2,Se,C,5,H,8,O,2,Se and C,7,H,9,NO,2,Se were proposed.
