Abstract:

The flash extraction method was employed to extract polyphenols from the fruits of Siraitia grosvenorii, and the extraction parameters were optimized by means of response surface methodology. The optimum conditions were obtained as follows: biomass-to-solvent ratio 1:25, voltage 153 V, temperature 8.5 ℃, time 3.5 min, and the polyphenols yield 2.73%. The mathematical model of flash extraction of polyphenols from Siraitia grosvenorii was established and the optimal condition was obtained, which offered reference for the industrial extraction of polyphenols of Siraitia grosvenorii.

Key words: Siraitia grosvenorii, polyphenols, flash extraction, response surface methodology
