Abstract: Studies were made on extracting flavones from cole pollen. The effects of different solvent concentrations, proportion of material and solution, extraction time and extraction temperature on yield were discussed. Box-Behnken center-united experiment design and response surface methodology were used to optimize the extraction technology of flavones of cole pollen. The optimum extraction conditions showed that the temperature 74 ℃, concentration of ethanol 88%, the ratio of material to solvent 1:10, extraction time 48 min.

Key words: cole pollen, flavones, response surface methodology
