BACKGROUNDPhenolic compounds are the predominant ingredients in apple pomace. However, polyphenols from industrial apple pomace, which usually consists of several cultivars, have not been studied in detail. The present work focused on the antioxidant assay and HPLC analysis of polyphenol‐enriched extracts from industrial apple pomace.
RESULTSSix fractions of apple polyphenols, API to APVI, were acquired...
In order to establish a novel technique of separation and analysis of EGCG from tea polyphenols using high-speed countercurrent chromatography (HSCCC), a set of HSCCC apparatus was applied to isolate and purify EGCG from tea polyphenols using two-phase solvent system composed of n-hexane-ethyl acetate-ethnol-water-acetic acid (1:5:1:5:0.25, v:v) in tail to head elution model, which the upper phase...
