In addition to the listed GSLs, an unidentified isomer of 2h3mPe (149), with the desulfo derivative closely eluting yet chromatographically distinct from d 149, was detected at ca. 0.01 μmol/g dry wt. in P. virginica (both accessions), and unidentified isomers of 2mBu and 3mPe at trace level were detected in N. officinale (Section 2.2.4.). Searched for but not detected in any of the three species: 10mSOd, 10mSd, Pren, Buen, the typical A. thaliana GSLs 3hPr, 4hBu, 3BzOp, 4BzOb, 5BzOp, as well as BCAA-derived 1mEt, 1mPr, 2mPr, 2mBu, 2h2mBu, 3mPe, 3hmPe, 2h3mPe. GSL numbers labelled with an asterisk indicate tentative identification due to lack of an authentic standard, while individual data with an asterisk indicate lack of MS2 confirmation of analyte identity due to low level. b Identity confirmed by comp. witn an authentic std. using UHPLC-QToF (Supplementary Fig. S4F-G).
表5 北美独行菜(*Planodes virginica*)、豆瓣菜(*Nasturtium officinale*)和草地蔊菜(*Rorippa sylvestris*)不同器官中源自脂肪族氨基酸的硫代葡萄糖苷(glucosinolates, GSLs)谱图。a 甲基亚磺酰烷基(MeSO烷基,MeSOalkyls)、甲基磺酰烷基(MeSO₂烷基,MeSO₂alkyls)以及甲硫基烷基(MeS烷基,MeSalkyls);n=4、n=5、n=6、n=7、n=8、n=9*;n=8*、n=5*、n=6*、n=7、n=8、n=9*;64、72、67、66、69、68*;80、94*、88*、87、92[89]*。单位:μmol/g 干重。 北美独行菜(种质库编号1,采自肯塔基州) 根:0.04、0.02、0.28、0.79、0.05、0.01*,未检出(n.d.)、*、0.02、0.02、未检出(n.d.) 茎:0.01、0.04、0.28、0.78、0.05、0.01*,未检出(n.d.)、未检出(n.d.)、未检出(n.d.)、未检出(n.d.)、未检出(n.d.) 叶:0.01、0.02、0.18、0.48、0.05、0.01*,未检出(n.d.)、未检出(n.d.)、未检出(n.d.)、未检出(n.d.)、未检出(n.d.) 长角果:0.02、0.04、0.43、1.20、0.09、0.03*,未检出(n.d.)、未检出(n.d.)、未检出(n.d.)、未检出(n.d.)、未检出(n.d.) 种子^b:0.10、0.38、4.81、30.48、0.05*,痕量(tr.)、痕量(tr.)*、0.48、1.3、痕量(tr.)* 北美独行菜(种质库编号2,采自俄亥俄州) 叶:痕量(tr.)^b、0.04、0.20、1.2、1.7、0.11、0.02*,未检出(n.d.)、未检出(n.d.)、未检出(n.d.)、未检出(n.d.)、未检出(n.d.) 豆瓣菜 种子(俄亥俄州批次):痕量(tr.)*、0.02、0.09、3.9、3.9、0.04、0.17、未检出(n.d.)、0.8、4.8、2.0、未检出(n.d.) 种子(约翰批次):痕量(tr.)*、0.02、0.12、4.9、5.5、0.12、0.12、未检出(n.d.)、1.5、5.1、2.5、未检出(n.d.) 草地蔊菜 种子:未检出(n.d.)、未检出(n.d.)、未检出(n.d.)、0.06、56、3.2、1.1、未检出(n.d.)、未检出(n.d.)、0.02*、100.05* 注释a:本数据(平均含量)与样本量N与表4来自同一采集批次。除上述所列硫代葡萄糖苷外,在两份种质的北美独行菜中均检出一种2h3mPe的未鉴定异构体(编号149),其脱硫衍生物的洗脱行为与d149极为接近,但色谱行为存在差异,含量约为0.01 μmol/g干重;在豆瓣菜中还以痕量水平检出2mBu和3mPe的未鉴定异构体(详见2.2.4节)。本研究对以下硫代葡萄糖苷进行了检索,但在三个物种中均未检出:10mSOd、10mSd、Pren、Buen,以及模式植物拟南芥(Arabidopsis thaliana)典型的硫代葡萄糖苷3hPr、4hBu、3BzOp、4BzOb、5BzOp,同时还有支链氨基酸(branched-chain amino acids, BCAA)衍生的1mEt、1mPr、2mPr、2mBu、2h2mBu、3mPe、3hmPe、2h3mPe。带星号标注的硫代葡萄糖苷编号表示因缺乏对照品而仅为暂定鉴定;单个数据带星号则表示因含量过低,未获得二级质谱(MS²)确认其分析物身份。 注释b:经与对照品采用超高效液相色谱-四极杆飞行时间质谱(UHPLC-QToF)比对确认身份(补充图S4F-G)。
