Abstract:

The chemical components in sorghum husk are analyzed and identified by high performance liquid chromatography tandem with quadrupole electrostatic field orbital trap mass spectrometry and screened for inhibition of xanthine oxidase activity components by high performance liquid chromatography. The experiment is performed on a Hypersil GOLD C18 column (2.1 nm×30 nm, 3 μm) with a gradient elution of 0.1% formic acid water (A)-acetonitrile (B) at a flow rate of 1.0 mL/min and a sample volume of 10 μL. The mass spectrometry analysis is performed using an ESI ion source and data are collected in positive ion mode. The data obtained are analyzed using Xcalibur 4.1 software in combination with a database, and a total of 27 chemical components are identified. Six chemical components, namely acacetin, puerarin, apigenin, phlorizin, isorhamnetin and fisetin, are screened for activity, and apigenin and fisetin are found to exhibit strong inhibitory activity on xanthine oxidase (XO) with IC50 of 18.11 and 34.59 μmol/L, respectively.
