Abstract:

Based on single factor test, orthogonal test design was applied to optimize the extraction technology of polyphenols from crushed pomegranate seed (20 mesh). Results showed that temperature and ratio of solid to liquid had significant effects on extraction yield of polyphenols. Under optimized conditions [with 50% ethanol as extraction solvent, at the ratio of material to the solvent of 1:20 (g/ml), extracting for 2.0 h at 50 ℃], the extraction yield of polyphenols reached 12.07 mg/ g.

Key words: pomegranate seed, extraction yield, polyphenols
