Embodiment Construction

[0014] 1. Embodiment:

[0015] (1), take 50kg of turmeric, wash the turmeric, pulverize, finely grind, pass through a 40-120 mesh sieve, and then grind and sieve the material on the sieve to get turmeric slurry: the mass percentage concentration of turmeric slurry is 8-10 %, turmeric particles reach 40-120 mesh;

[0016] (2), the turmeric slurry enters the vibrating sieve, and sieves out the turmeric fiber;

[0017] (3), screen out the slurry of turmeric fiber and enter the multistage cyclone separator to separate turmeric starch; obtain about 100L of slurry;

[0018] (4), after separating the turmeric starch, the slurry is precipitated, and the precipitate is used to produce turmeric saponin, and the supernatant is concentrated through nanofiltration; 2 to 3 L of concentrated solution is obtained;

[0019] (5), after the concentrated solution is adsorbed by the macroporous resin, it is eluted with an ethanol solution with a concentration of 60 to 75% by mass percent;

[00...

Abstract

The invention brings forward a method of extracting water-soluble saponin from yellow ginger. A technical scheme provided in the invention is as follows: yellow ginger is used as a raw material and is crushed, fibers are sieved, yam starch is separated by using eddy flow, obtained slurry is deposited so as separate water-insoluble saponin, a supernatant is subjected to nanofiltration, condensation, adsorption with a resin, elution with an ethanol aqueous solution, recovery of ethanol, condensation and drying so as to obtain the water-soluble saponin from yellow ginger. According to the invention, the content of water-soluble saponin in a concentrate is substantially increased, and the advantages of simple operation and low cost are obtained.

Description

technical field [0001] The invention belongs to the field of phytochemical engineering, and in particular relates to a method for extracting water-soluble saponins from yellow ginger. Background technique [0002] Turmeric water-soluble saponins have pharmacological activities such as anti-inflammatory, expectorant, asthma, lowering blood fat, and improving cardiovascular function. Turmeric rhizome contains a variety of dioscins (water-soluble saponins and water-insoluble saponins). Among them, water-soluble saponins are the main raw materials for the production of Di'ao Xinxuekang and Wei'aoxin tablets for the treatment of coronary heart disease. In industry, the saponins in the rhizome of yam are often directly acid-hydrolyzed into diosgenin, which is used to synthesize various corticosteroids and sex hormones. However, the disadvantage is that in the process of extracting diosgenin, such as the separation method to extract diosgenin, the turmeric soaking solution (conta...
