An internal standard, [(13)C][indole-2]-indole-3-butyric acid, was synthesized from indole-2[(13)C] and was shown to be effective for the quantitative determination of indole-3-butyric acid from plant tissue. When this standard was used along with [(13)C(6)]indole-3-acetic acid, both indolic auxins could be quantified from the same tobacco (Nicotiana tabacam) leaf sample by isotope dilution analysis using selected ion monitoring gas chromatography-mass spectrometry for detection.
内标物[(13)C][吲哚-2]-吲哚-3-丁酸由吲哚-2[(13)C]合成,可有效定量测定植物组织中的吲哚-3-丁酸。当与[(13)C(6)]吲哚-3-乙酸一起使用时,通过选择离子监测气相色谱-质谱法检测,同位素稀释分析可从同一烟草(Nicotiana tabacam)叶片样品中同时定量测定这两种吲哚类植物生长素。
