In order to extend the source of anthocyanin which is a kind of natural anti - oxidant pigment, and develop high value application of halophytes. [ Method ] Based on the traditional organic solvent extraction, the Suaeda heteroptera of halophyte was used as raw material, the anthocyanins of the material extracted by three different extraction methods for the first time were studied: A: purified before leaching extraction; B: fat freeing before leaching extraction method; C: homogenated before leaching extraction. Via absorption spectra, the absorbance values at maximum absorption wavelength of the extract based on spectrophotometry were compared and the total content of monomeric anthocyanins was determined by the pH differential method. [ Result ] Through the study of extracts gained by three extraction methods, the result showed that the extract of method B had maximum absorption and the highest content of total anthocyanins, the extract of method A had the highest content of monomeric anthocyanins. [ Conclusion ] The experiments could better study and compare the anthocyanins content of extracts gained from the Suaeda heteroptera of halophyte by different methods, and more appropriate extraction method could be selected based on the extraction efficiency requirements in order to more fully and more efficiently make use of the Suaeda heteroptera of halophyte which is an important source of anthocyanins.
