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

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.
Description
technical field [0001] The invention belongs to the field of deep processing of agricultural products, in particular to a method for simultaneously extracting polyphenols and flavonoids. Background technique [0002] Polyphenols and flavonoids have strong physiological activities such as anti-tumor, anti-oxidation, anti-bacterial, anti-cancer, scavenging free radicals and preventing cardiovascular and cerebrovascular diseases. They are a class of natural antioxidants worth developing. [0003] Olives have been planted in my country for more than 2,000 years, and are currently mainly distributed in Longnan, Fujian, Guangdong, Guangxi, and Hainan provinces. A large number of studies have shown that there are many substances beneficial to the human body in olives, from pulp to nuts, which are of great value to human health. The current utilization of olives is mainly used for pressing olive oil, but there is almost no deep development and utilization of olive pits and olive ke...
