Embodiment 1

[0028] 1.5 kg of dried 40-mesh cherry blossom powder was treated with 30KHz ultrasonic waves for 20 minutes, and then put into extraction kettle I7 and extraction kettle II10. Set the extraction pressure to 35MPa, the extraction temperature to 65°C, the temperature of the separation tank I13 to 70°C and the pressure to 6MPa, the pressure of the separation tank II16 to 4.5Mpa, and the temperature of the separation tank II16 to 45°C. Static extraction was performed for 0.5 hours first, followed by dynamic extraction for 1 hour to collect non-polar components. Use ethanol with a concentration of 95% as the entrainer, and the weight of ethanol is 1kg, dynamically extract for 2 hours, and collect the extract. Combine two extracts, concentrate to obtain 36g of cherry blossom extract.

Embodiment 2

[0030] Put 1.5 kg of dried 10-mesh cherry blossom powder into the extraction kettle I7 and the extraction kettle II10 after ultrasonic treatment at 50KHz for 40 minutes. Set the extraction pressure to 15MPa, the extraction temperature to 40°C, the temperature of the separation tank I13 to 55°C and the pressure to 8MPa, the pressure of the separation tank II16 to 5Mpa, and the temperature of the separation tank II16 to 40°C. Dynamically extract for 2 hours to collect non-polar components. Using ethanol with a concentration of 80% as entrainer, the weight of ethanol is 1.5kg, the extraction pressure is 25MPa, the extraction temperature is 45°C, dynamic extraction is performed for 2h, and the extract is collected. Combine two extracts, concentrate to obtain 33g of cherry blossom extract.

Embodiment 3

[0032] 1.5 kg of dried 80-mesh cherry blossom powder was treated with 28KHz ultrasonic wave for 60 minutes, and then put into extraction kettle I7 and extraction kettle II10. Set the extraction pressure to 25MPa, the extraction temperature to 55°C, the temperature of the separation tank I13 to 60°C, and the pressure to 6MPa, the pressure of the separation tank II16 to 5Mpa, and the temperature of the separation tank II16 to 45°C. Static extraction was performed for 0.5 hours first, followed by dynamic extraction for 1 hour to collect non-polar components. Use ethanol with a concentration of 60% as the entrainer, and the weight of ethanol is 0.5Kg. Dynamically extract for 1 hour, and collect the extract. Combine two extracts, concentrate to obtain 30g of cherry blossom extract.

Abstract

The invention provides a method for continuously extracting effective components in oriental cherries by using supercritical carbon dioxide. The method comprises the following steps of finely grinding raw materials by using 20-50KHz ultrasonic waves, then, extracting the raw materials at the temperature of 32-90 DEG C and the pressure of 8-60MPa for 1-2h by using the supercritical carbon dioxide, and extracting the raw materials in a supercritical state for 1-2h by using 40-100% ethanol as an entrainer to obtain a safe, pollution-free and high-quality oriental cherry extract, wherein the weight of the entrainer is 1-1000% of the weight of the raw materials, a separation kettle I has the pressure of 5-12Mpa and the temperature of 32-90 DEG C, and a separation kettle II has the pressure of 4-6Mpa and the temperature of 30-50 DEG C. Due to the adoption of supercritical equipment with double extraction kettles, the continuous extraction can be realized, the production period can be shortened, and the production efficiency can be increased. The method provided by the invention is efficient and safe, incapable of damaging active components, high in repeatability, short in process flow and convenient in operation.

Description

technical field [0001] The invention relates to a method for extracting and separating active ingredients of plants, in particular to a method for continuously extracting active ingredients in cherry blossoms by using supercritical carbon dioxide extraction technology. Background technique [0002] Cherry blossom (Prunus Yedoensis) is a plant of the Rosaceae family. It not only has high ornamental value, but also has a variety of medicinal values. Cherry tree leaves and cherry blossoms are used as traditional Chinese medicinal materials, which have the effects of relieving cough, relieving asthma, moistening intestines, and relieving alcohol. Studies have shown that the active ingredients of cherry blossoms are mainly flavonoids, including cherry blossoms, astragalin, isoquercitrin, cyanidin-3-glucoside, cyanidin-3-rutinoside, cherry blossoms Flavin, genistein, quercetin, prunin-4'-0-3-glucopyranoside, kaempferol-3-O-arabinofuranoside, kaempferol-3-O-β-wood Glycosides, geni...
