Abstract
The invention discloses an extracting process of litchi polysaccharide, relates to an extracting process of nutritional ingredients in the litchi and in particular relates to the extracting process of litchi polysaccharide. The invention provides the extracting process of the litchi polysaccharide which is short in time consumption and good in extracting solution. The extracting process adopts the technical scheme of extracting the polysaccharide in the litchi by utilizing a microwave method; the process steps are as follows: removing the shell and the core of the litchi, soaking for 10-20 hours in water, and pulping; placing the slurry in a microwave oven, adding water with a feed liquid ratio of (1:6)-(1:12), setting the microwave powder to 480 W-800 W, and microwave-extracting for 8-12 minutes; filtering and centrifuging for 10-15 minutes, and taking liquid supernatant for concentration; adding 60%-80% of the alcohol solution, stewing for 10-15 hours; taking the liquid supernatant for concentration and drying to obtain the finished product.
Description
Technical field
The present invention relates to the extraction process of nutritive ingredient in the lichee, more particularly, relate to the extraction process of lichee polysaccharide.
Background technology
From the sixties in 20th century polysaccharide physiological active functions be found after, the research of relevant polysaccharide is subject to the attention of countries in the world day by day.That active polysaccharide has is antiviral, strengthening immunity, antitumor, delay senility, the multiple efficacies such as hypoglycemic, anticoagulation, so polysaccharide has important using value.
Lichee belongs to sapindaceous plant, mainly is distributed in the ground such as Guangdong, Guangxi, Fujian, Hainan and Taiwan in China, is the fruit tree of South China's cultivated area maximum.For a long time, lichee is regarded as " treasure in the fruit " always because having higher nutritive value and multiple nourishing beauty treatment effect.The lichee whole body all can be used as medicine, have promote the production of body fluid, beneficial blood, the effect such as regulate the flow of vital energy, relieve the pain.Put down in writing according to Compendium of Material Medica: " often eat lichee and can mend brain and enhancing fitness, the treatment scrofula, beneficial spleen whets the appetite; Drying can invigorating premordial QI, can be used as puerpera and old weak person's tonic ".Discovered in recent years, the α that extracts from Semen Litchi-methylene cyclopropylamino acid has obvious hypoglycemic activity, and the aqueous extract of nuclear is the highly efficient depressor of hepatitis B virus, the obvious reducing blood lipid of Kernel Oil From Litchi Chinensis Sonn Seed tool.To the litchi pulp part, comprise that the extraction of lichee polysaccharide still belongs to blank at present.
Summary of the invention
The present invention is exactly for the problems referred to above, and the extraction process of a kind of weak point consuming time, lichee polysaccharide that extraction effect is good is provided.
In order to realize above-mentioned purpose of the present invention, the present invention adopts following technical scheme, and the present invention utilizes microwave method, and the polysaccharide in the lichee is extracted, and processing step is: dried Fructus Litchi is shelled, stoning, soaks 10～20h, making beating in water; Slurries are placed microwave oven, and adding solid-liquid ratio is the water of 1:6～1:12, and the power that microwave is set is 480～800W, microwave extraction 8～12min; Filtration, centrifugal 10～15min, get supernatant concentration; The ethanolic soln of adding 60～80% leaves standstill 10～15h; Centrifugal, get supernatant concentration, drying, finished product.
Beneficial effect of the present invention.
The present invention's weak point simple to operate, consuming time.
Extraction yield of the present invention is 95%.
Embodiment
Processing step of the present invention is: dried Fructus Litchi is shelled, stoning, soaks 10～20h, making beating in water; Slurries are placed microwave oven, and adding solid-liquid ratio is the water of 1:6～1:12, and the power that microwave is set is 480～800W, microwave extraction 8～12min; Filtration, centrifugal 10～15min, get supernatant concentration; The ethanolic soln of adding 60～80% leaves standstill 10～15h; Centrifugal, get supernatant concentration, drying, finished product.
The present invention selects solid-liquid ratio, microwave power, the extraction time influence factor of lichee polysaccharide extraction effect the most, can see Table 1.
Table 1 three factors are on the impact of lichee polysaccharide extraction effect.
