The invention belongs to the field of farm product deep processing, and particularly relates to a method for simultaneously extracting polyphenol and flavones. After the olive nut dehulling, red peels and kernels are separated; the separated red peels are dried, crushed and sieved, and are added into a mixed solution of ethanol and water; filtering is performed after heating extraction; filter liquid is collected; concentration and drying are performed to obtain the polyphenol and the flavones; the yield and the purity are high; the operation of the extraction method is simple; convenience and high speed are realized; the industrial production is facilitated.

Example Embodiment

[0015] Example 1
[0016] (1) After the olive pits are dehulled, the red skin is separated from the nuts, and the separated red skin is naturally dried at room temperature (25°C), crushed, and passed through a 60-mesh sieve;
[0017] (2) Take 50 g of the sieved red skin obtained in step (1) and place it in a beaker, and add 500 mL of a mixture of ethanol and water with a volume ratio of 3:1, and place the beaker in a 50°C constant temperature water bath shaker , Stir and extract the red skin for 30min, centrifuge and filter, collect the filtrate,
