Abstract:

Ultrasound-assisted extraction for the flavonoids-enriched extract from tartary buckwheat seedling was investigated. Response surface methodology, based on the central composite design of three variables with five levels, was employed to study the effect of extraction conditions on the extraction yield of total flavonoids. An experimental extraction yield of 3.64% was achieved under the optimum extraction conditions of 76.2% ethanol volume fraction, liquid/solid ratio of 28.5:1 and extraction time of 25 min. This study confirms the efficiency of ultrasound-assisted extraction as a simple, inexpensive and effective method to improve the extraction of flavonoids and the great potential of tartary buckwheat seedling as a health food and a resource of flavonoids.

Key words: tartary buckwheat seedling, flavonoids, ultrasound-assisted extraction, response surface methodology
