Medical application of kiwi fruit extract in preparation of medicine for improving memory

Abstract

The invention discloses medical application of kiwifruit extracts in preparation of drugs for improving memories, and relates to the novel application of kiwifruits in food, beverages, drugs, healthcare products and combinations. Kiwifruits are safe, nonpoisonous and free of side effects as fruits, simple in extracting method, convenient to operate, and capable of being prepared to food or healthcare products or beverage products to be used for nutrition and healthcare.

Description

technical field

[0001] The invention discloses the medical use of a kiwi fruit extract in the preparation of memory-improving medicine, relates to the new use of kiwi fruit in food, beverage, medicine, health care product and composition, and belongs to the technical field of health food. Background technique

[0002] Kiwi fruit is the fruit of Actinidiaceae plant Actinidia, also known as sheep fruit or kiwi fruit, is a climbing plant, there are 66 varieties in the world, and there are 62 in our country, mainly including kiwi fruit, Chinese kiwi fruit, Gezao Kiwifruit, delicious kiwifruit, etc., they are mainly distributed in Northeast China, North China, Central China, Northwest China and other regions. Kiwi fruit has a lot of fat and juice, and is rich in nutrients. In addition to rich nutrients such as vitamins, polyphenols and trace elements, it also contains amino acids, natural inositol, folic acid, carotene, etc. that are not common in other fruits. It is a high-qual...

Examples

Embodiment 1

[0017] Wash 3000g of kiwi fruit with deionized water, pulverize and beat with a mixer, pass through a 100-mesh sieve, and extract 3 times with water at a temperature of 75°C at a solid-to-liquid mass ratio of 1:20, the first time for 3 hours, and the second time 2 hours for the first time, 1 hour for the third time, combine the water extracts for 3 times, and centrifuge at 2000 rpm for 10 minutes. After discarding the precipitate, filter it with a 100-mesh filter cloth to obtain the filtrate, and concentrate the filtrate under reduced pressure to a relative density of 1.00 (70°C), freeze-dry the concentrate at -30°C for 96 hours to obtain 53.15 g of kiwi fruit extract.

Embodiment 2

[0019] Wash 3000g of kiwi fruit with deionized water, pulverize and beat with a mixer, pass through a 200-mesh sieve, press the solid-to-liquid mass ratio of 1:40, and the temperature is 85°C, water extraction 2 times, the first time for 3 hours, the second time After 2 hours, the water extracts were combined twice, centrifuged at 3000 rpm for 15 minutes, and the precipitate was discarded, then filtered with a 200-mesh filter cloth to obtain the filtrate, and the filtrate was concentrated under reduced pressure to a relative density of 1.20 (80°C). The concentrate was freeze-dried at -60°C for 72 hours to obtain 40.22 g of kiwi fruit extract.

Embodiment 3

[0021] Wash 4000g of kiwifruit, crush it with a mixer, and extract it with water at 80°C for 3 times at a ratio of solid-liquid mass ratio of 1:30. Centrifuge for 15 minutes per minute, discard the precipitate, and then filter with a 200-mesh filter cloth to obtain the filtrate; concentrate the filtrate under reduced pressure at 60°C~80°C to a relative density of 1.00~1.20, and then filter it at -30~-60 It can be obtained after lyophilization at ℃ for 72~96 hours.

[0022] In order to prove whether the kiwifruit extract of the present invention has the function of improving memory, the new application will be shown through the following experiments:
