The sea red bean for leguminous plants of the genus red bean. Distribution in our country in the south and southwest, laid a convergence effect, can be used to relieve diarrhea. Studies on its chemical composition is less, mainly flavonoids and saponins class, with the continuous development of Chinese medicine extraction technology, the chemical composition in the sea of red bean extract technology is in constant developing.
the sea red beans belong to small trees, leaves twigs slightly pilose. Seeds suborbicular to elliptic, 5 - long 8 mm wide. 4. 5 - 7 mm, bright red, shiny. Raceme solitary in axillary or at the top of the branches in panicle, pubescent; Flowers small, white or pale yellow, fragrant, with short stalk.

sea red bean in the chemical composition of sea red bean seeds contained in the chemical composition and its main chemicals that have the effect of stigmasterol, stigmasterol dextrose glucoside, galactitol, polysaccharides and protease inhibitors with eight kinds of trypsin inhibitors, including galactitol seeds, stigmasterol dextrose glucoside, a minus Spinach sterol, beta Sitosterol and rich in protein, fatty acids are palmitic acid, stearic acid, arachidic acid, 24 alkanes acid, 28 carbon olefine acid, oleic acid, linoleic acid, 20 carbon olefine acid, seed oil also contains myristic acid, and more than 50% of the total combined with fatty acid in the seed oil of linoleic acid, also contain a small amount of linolenic acid, in addition, the red bean wooden part contains robinia flavin, chalcone, riveting purple flowers, fujian tea, dihydrogen robinia flavin, 2, 4 - Dihydroxy benzoic acid, the bark contains glucose, cystic acid, oleanolic acid and their glucose saponins and stigmasterol dextrose glucoside, contains oleanolic acid in roots and cystic acid, 28 alcohol is contained in the leaves, galactitol, beta Sitosterol dextrose glucoside and stigmasterol.
because of its high medicinal value, so in recent years of traditional Chinese medicine extraction area has a high commercial value, with the continuous development of traditional Chinese medicine extraction technology, the chemical composition in the sea of red bean extract technology is in constant developing.
days extraction to extract the sea red bean test
2 kg dry sea red bean stem and leaf, crushing backflow extraction with 95% ethanol by Chinese medicine extraction equipment after 3 times, 55 extract reduced pressure concentration. 7 g extract, its suspended in the water, in turn, with petroleum ether, ethyl acetate and water saturation n-butyl alcohol extraction, 2 respectively. 7 g, 10。 6克,26岁。 1g。 Higher extraction efficiency.
centrifugal extraction machine to extract the technological characteristics of the red bean
to adapt to the strong performance - Compared with the traditional van and extraction tower equipment, under the effect of centrifugal force, the remaining time is short, split phase quickly, to adapt to the wide range of flow ratio, and processing power; By changing the weir plate and frequency control of motor speed can meet the different density and viscosity of liquid materials;
the material stock of small - Two-phase material stock in the equipment is small, short contact time, more suitable for processing because of long time volatile activity and variability of materials such as antibiotics, etc. , of course, individual system needs two phase together contact time long also can operate separately.
extraction efficiency of high - Phase equilibrium set up fast, easy to implement series single stage or multistage counter-current or wrong washing and extraction, high mass transfer efficiency and grade efficiency approaching 100%, stop not to undermine the established after concentration distribution at different levels, can at any time at all levels of sampling, facilitate testing.
