    • The present invention relates to a method for extracting at least one isotope-labelled compound from a complex matrix sample comprising a) contacting said complex matrix sample with an extraction solvent comprising a water-miscible organic solvent and water, b) binding cationic isotope-labelled compounds to a solid adsorbent in the presence of an acid, c) collecting non-cationic isotope-labelled compounds not binding to said solid adsorbent and/or eluting said cationic isotope-labelled compounds from said solid sorbent, d) thereby extracting at least one isotope-labelled compound from said complex matrix sample. The present invention further relates to a method for determining at least one isotope-labelled compound comprised in a complex matrix sample, comprising the aforesaid steps and the further steps of separating cationic and/or non-cationic isotope-labelled compounds by chromatographic steps, and determining, cationic and/or non-cationic isotope-labelled compounds. Further, the present invention relates to kits and uses related to said methods.
    • 本发明涉及从复合基质样品中提取至少一种同位素标记的化合物的方法,其包括a)使所述复合基质样品与包含水混溶性有机溶剂和水的提取溶剂接触,b)结合阳离子同位素标记的 化合物在酸存在下与固体吸附剂接触,c)收集不与所述固体吸附剂结合的非阳离子同位素标记化合物和/或从所述固体吸附剂洗脱所述阳离子同位素标记化合物,d)由此提取至少一种 来自所述复杂基质样品的同位素标记的化合物。 本发明进一步涉及用于确定包含在复合基质样品中的至少一种同位素标记化合物的方法,其包括上述步骤和通过色谱步骤分离阳离子和/或非阳离子同位素标记化合物的其他步骤,以及 测定阳离子和/或非阳离子同位素标记的化合物。 此外,本发明涉及与所述方法有关的试剂盒和用途。
