Problems solved by technology

[0009] In the current actual production, the extraction process has been the acid hydrolysis fermentation process that has been used for 50 years. The extraction time is long, the waste of raw materials is large, the environmental pollution is large, the product quality is low, the production cost is high and there is no added value. The problem in production is technology. There is no major breakthrough in the field of saponin production, and the production process of natural fermentation, hydrochloric acid hydrolysis, and solvent gasoline extraction has been used in the production of saponin,

Embodiment

[0045] Weigh 1000Kg of fresh turmeric, slice it after cleaning, break the wall with microwave equipment, put the material into a high-shear emulsification tank, and add ethanol solvent to shear for 30 minutes. Emulsified to 400 mesh. Dynamic continuous extraction equipment is used to cyclically extract materials to extract water-soluble saponins; the saponin solution is vacuum-concentrated and dried to obtain total saponins as residues. Add water to suspend, add 20% hydrochloric acid and heat to react for 6 hours. Filter out the acid solution, wash the acid solution precipitate with water until neutral, and dry to obtain crude saponin. Add absolute ethanol to dissolve crude aglycone, and add active carbon powder of equal weight to absorb impurities. Activated carbon powder was separated by filtration, and the filtered solvent was filtered through a microporous membrane to remove impurities, and the solvent was evaporated under reduced pressure to completely precipitate needle-...

Abstract

This invention provides a new technology of cleaning production that extract sapogenin from dioscorea zingiberensis wright. It uses rhizome of fresh dioscorea zingiberensis or fresh dioscorea nipponica that are 2 -3 perennials as raw material. Its technology is that: raw material-microwave processing-ultramicro-pulverization-dynamic state continuous extracting-rectification-hydrolization-crude sapogenin-dissolving adsorption for purification-rectification-crystallization-drying-depurating sapogenin. This invention provides a new technology that produces diosgenin. Its technology is advanced, investment is little, material expenditure is low, production yield is high, quality is satisfactory, production period is so short that extracting technology can complete in 20 hours. It has no pollution. Content of COD in the water is less than 300mg/l.

Description

a technical field [0001] The invention adopts a new clean production process for extracting saponin from Dioscorea scutellaria, in particular adopts a series of advanced production processes and technologies to achieve clean production, shortens the extraction time, increases the extraction efficiency, and solves pollution discharge at the same time. Two background technologies: [0002] Saponin (diosgenin), which is extracted from turmeric or pangolin, is the precursor of steroid hormone drugs and accounts for 70% of the raw materials for the synthesis of steroid drugs. Steroid hormone drugs are the second largest class of drugs after antibiotics in the world. At present, there are as many as 292 kinds of steroid hormone drugs produced in the world. Steroid hormone drugs have strong anti-infection, anti-allergy, anti-virus and anti-shock pharmacological effects, and are widely used in clinical medicine at home and abroad. So far, diosgenin is still the most ideal raw mate...
