Embodiment 1

[0017] The kumquat dry powder is passed through a 40-mesh sieve, and added to the ethanol solution with a concentration of 70%. The mass ratio of the kumquat dry powder to the ethanol solution is 1:30. It is extracted by ultrasonic enhancement. The extraction temperature is 50°C, the extraction time is 90min, and the extraction is performed once. , the ultrasonic power is 200W, then centrifuge to obtain the supernatant and filter, evaporate and concentrate to 1 / 5 of the original volume, precipitate with ethanol, filter, and centrifuge the filtrate to obtain the crude extract. The measured polysaccharide extraction rate is 4.8%.

Embodiment 2

[0019] Kumquat dry powder is passed through a 40-mesh sieve and added to a 70% ethanol solution. The mass ratio of kumquat dry powder to ethanol solution is 1:30. Ultrasonic enhanced extraction is carried out at 50°C for 80 minutes for extraction twice. , Ultrasonic power is 180W, 220W respectively, then centrifuge to obtain the supernatant and filter, evaporate and concentrate to 1 / 5 of the original volume, precipitate with ethanol, filter, and centrifuge the filtrate to obtain the crude extract. The measured polysaccharide extraction rate is 7.2%.

Embodiment 3

[0021] Kumquat dry powder is passed through a 40-mesh sieve and added to a 70% ethanol solution. The mass ratio of kumquat dry powder to ethanol solution is 1:30. Ultrasonic enhanced extraction is carried out at a temperature of 50°C and an extraction time of 60 minutes for 3 extractions. , the ultrasonic power was 160W, 200W, 240W respectively, then centrifuged to obtain the supernatant and filtered, evaporated and concentrated to 1 / 5 of the original volume, precipitated with ethanol, filtered, and the filtrate was centrifuged to obtain the crude extract. The extraction rate of polysaccharide was measured 7.6%.

Abstract

The invention provides an extraction method of kumquat polysaccharides. Dry kumquat powder is sieved with a 40-mesh sieve, the sieved kumquat powder is added to ethanol solution with concentration being 70% and is subjected to ultrasonic-assisted extraction, supernatant is obtained after centrifugation, is filtered, is evaporated and concentrated until the volume is 1 / 5 of the original volume, is precipitated by ethanol and is filtered, and the filtrate is centrifuged to obtain the crude extracts. The extraction method is characterized in that the ultrasonic-assisted extraction process is as follows: the extraction time is 60-90 minutes, extraction is carried out once to three times, and the ultrasonic power is gradually increased. By adopting the extraction method, the extraction time can be shortened and the polysaccharide extraction rate can be improved, and the method has the characteristics of time saving and high efficiency.

Description

technical field [0001] The invention relates to a method for extracting kumquat polysaccharides, which belongs to the field of plant extraction. technical background [0002] Polysaccharides, referred to as polysaccharides, are polysaccharides formed by connecting more than 10 monosaccharide groups through glycosidic bonds. Polysaccharides are widely distributed and are essential components of all living organisms. Polysaccharides can not only be used as energy storage substances, but also have many biological activities. For example, polysaccharides can specifically inhibit the formation of tumor blood vessels, and induce apoptosis to inhibit tumors. It is harmless to normal cells and is superior to traditional surgical treatment and chemotherapy. . Because polysaccharides play an extremely important role in various biological growth processes, coupled with their unique physical, chemical and biological properties, polysaccharides have become a research hotspot in the f...
