A new analytical method for the determination of piperine and its isomers in egg yolk and albumen is described here. The method was successfully applied to the determination of piperine deposits in eggs egg yolk and albumen after feeding hens with piperine-spiked feed. The detection limit for piperine This is a preview of subscription content, log in to check access.

The piperonylic acid is removed by adjusting the pH; the fat-soluble substance being removed by adding ethyl ether; the piperine alkaloid being purified with acetone by recrystallization anddetected with HPLC, as well as characterized with IR.
The characterizations of piperine are discussed. The distribution of the thermodynamic equilibrium of stable conformations of four kinds of configurations of the molecular is calculated with Gibbs free energy at room temperature And IR spectra of the experimental were compared with the IR spectra of the theoretical.
With analysis, the methods of extraction, separation and purification of piperine in this paper achieve good results. Established models are in good agreement with the experimental results. This research is of great significance in guiding extracting process, building structural model and the characterization and application of piperine.
