Abstract

The invention discloses a method for preparing a cranberry extract and capsules thereof. The extraction method comprises the following steps: step 1, selecting raw materials, namely adopting fresh cranberry fruits, cleaning, removing the impurities and drying the skin; step 2, crushing the raw materials, namely stirring and crushing the raw materials obtained in the step 1, collecting the slurry and residues; step 3, performing ultrasonic extraction, namely adding a 75 percent ethanol solution 8 times of the volume of the slurry and residues, fully mixing, and performing ultrasonic treatment in an ultrasonic extractor, wherein the extraction time is 2-3 hours, and the extraction temperature is 40-60 DEG C; and step 4, performing vacuum filtering on the product obtained in the step 3, performing reduced pressure distillation on the filtrate, removing the moisture, ethanol and other volatile substances, thereby obtaining the solid cranberry extract.

Description

technical field [0001] The invention relates to the field of medicine extraction, in particular to a preparation method of cranberry extract and a capsule thereof. Background technique [0002] Cranberry is also called cranberry, cranberry, and cranberry. Its name comes from the original name "crane berry". It is named after the cranberry flowers that resemble the head and mouth of a crane. It is a berry with bright red skin that grows on dwarf vines. It grows in the cold wetlands of North America. The global production area is less than 40,000 acres. The high-quality cranberry contains air and can float on the water. Cranberry is a natural antibacterial health-care fruit, and it is the best natural food therapy to prevent and treat various bacterial infections of the urinary system, urethritis, cystitis, and chronic pyelonephritis in women. Cranberries are one of the few crops that can grow in acidic soil, and they need a lot of water. Once a vine starts to grow, it will c...
