Description
Summary:The conditions for extracting flavonoids from sweetpotato storage roots were studied in this paper. The optimum extracting conditions, which include extracting reagent 70% ethanol, extracting temperature of water-based heating 60 ℃, ratio of the storage root powder to the reagent 1∶60, and extraction time 1hour, have been obtained. The extracting rate of flavonoids reaches 87.15% under the optimum extracting conditions with one extracting cycle. Meanwhile, great genotypic variation in the flavonoid contents has been found, among the genotypes tested, the purple sweetpotato was showed to have the highest flavonoid content.
