Abstract:

In order to investigate the optimal extraction processing conditions of total flavonoids from Helianthus annuus L, orthogonal experiments were used to explore the effects of ethanol concentration, extraction temperature and extraction time on extraction rate of total flavonoids. The content of total flavonoids was determined by ultraviolet (UV) spectrometry method. Results indicated that the optimal extraction processing conditions were ethanol concentration of 50%, extraction temperature of 80 ℃and extraction duration of 2 h. The maximum extraction rate of 33.6436 mg/g was achieved under the optimal extraction conditions.

Key words: Helianthus annuus L., total flavonoids, optimization, extraction
