| titleOfInvention | Method for determining content of pyrroloquinoline quinone in biological sample by magnetic solid-phase extraction-capillary zone electrophoresis |
| abstract | The invention provides a method for determining the content of pyrroloquinoline quinone in a biological sample by magnetic solid-phase extraction-capillary zone electrophoresis and belongs to the field of a life analyzing technology. According to the method disclosed by the invention, SiO2 and adsorbents with different polarities are mixed; and the adsorbents have different selective properties on compounds with different hydrophobic properties, so that the effective separation can be carried out. A capillary electrophoresis method adopted by the invention adds a modifying agent beta-cyclodextrin; trifluoroacetic acid is firstly added into a capillary electrophoresis buffering system to solve the trailing problem of a peak in a capillary electrophoresis picture; and the symmetrical property of the peak is obviously better than that of a document report. The method disclosed by the invention is rapid and convenient, and can be used for determining the content of the PQQ in milk by utilizing a magnetic solid-phase extraction technology being combined with capillary electrophoresis firstly. Compared with a document method, the method disclosed by the invention improves the separation efficiency by 6 times. |
