doi:10.7506/spkx1002-6630-201604004

Abstract

Abstract:

Objective: To optimize the purification conditions for dihydroquercetin in larch roots. Methods: Single factor
method combined with Box-behnkn response surface methodology was used to optimize four factors including solid/liquid
ratio, recrystallization temperature and time by establishing a model involving four independent variables at three levels each
based on dihydroquercetin purity. Results: The optimal purification conditions were determined as recrystallized for 20 h at
5 ℃ at a liquid-to-solid ratio of 1:12 (dihydroquercetin: water). Conclusion: The results of the study can provide scientific
basis for the determination of the purification process of dihydroquercetin in industrial production.

Key words: dihydroquercetin, recrystallization, response surface methodology
