Abstract

The matrix solid‐phase dispersion (MSPD) was applied for extracting seven sulfonamides (SAs) in liver samples. The separation and determination were carried out by high‐performance liquid chromatography. The analytes were derivated with fluorescamine and detected with fluorescence detector. The types of dispersion adsorbents for MSPD were examined and the highest recovery was obtained when the diatomaceous earth was used as the dispersion adsorbent and the mass ratio of dispersion adsorbent to sample was 3:1. The acetone was used as the elution solvent. Under the optimal conditions, the linear range for determining the SAs in liver samples was 5.0–1000.0 ng/g. The porcine, chicken and cattle liver samples were analyzed and the average recoveries of seven SAs were higher than 84.6%.

A high-performance liquid chromatographic method was developed for separation of the furochromone fraction and for determination of visnagin in Ammi visnaga hairy root cultures. Lyophilized samples were extracted with chloroform:methanol (1:1, v/v) and purified on solid-phase extraction cartridges.
