| Abstract: | The process parameters of ethanol ammonium sulfate aqueous two-phase extraction of crocin from Gardenia jasminoides Ellis were studied. The effects of various factors on the extraction rate and partition coefficient of crocin from Gardenia jasminoides Ellis were investigated by single factor experiment. The extraction rate of crocin from Gardenia jasminoides Ellis reached 95.44%,when the mass fraction of ammonium sulfate was 23%,the mass fraction of ethanol was 25%,the concentration of Na Cl was 0.5%,the pH value was 8,the solid-liquid ratio was 9%,the extraction time was 45 min,and the extraction temperature was 20 ℃. |
