Abstract:

Response surface methodology was used to optimize the extraction processing of cactus flavonoids according to central composite design principle based on the single factor experimental results. Through screening of factors and levels, and the analysis of cross-interaction among factors, the optimal extraction conditions for cactus flavonoids were material-liquid ratio of 1:20, extraction temperature of 52.5 ℃, extraction time of 4 h, and alcohol concentration of 85%. The extraction rate of flavonoids was 0.784% under the optimal extraction conditions.

Key words: cactus, flavonoids, extraction, response surface methodology
