Abstract:

The optimum ultrasonic-assisted extraction process of polyphenols from hops was investigated using orthogonal array design and based on this, wild hops from 9 habitats of Xinjiang region were compared for difference in polyphenol content. Results indicated that an extremely significant difference in polyphenol content among the wild hops from 9 habitats of Xinjiang region was observed. Wild hops from Aleimalei town, Xinyuan county and Daxigou town, Huocheng county, Yili area exhibited the highest polyphenol content of 40.17 mg/g and the lowest of 26.37 mg/g, respectively.

Key words: wild hops grown in Xinjiang, polyphenol, extraction
