Abstract: By Folin-Ciocalteu colorimetric analysis and HPLC analysis, the changes of total phenolic content and phenolic compositions in sea buckthorn juice during chitosan clarification were studied. The results showed that after clarification, the total phenolic content decreased by 17.2%, the catechin, ferulic acid and p-coumaric acid in juice were lost and gallic acid and quercetin were destroyed by 87% and 62.5% respectively, but the chlorogenic acid changed little.

Key words: sea buckthorn juice, chitosan, clarification, phenolics
