Problems solved by technology

The traditional acid hydrolysis method is cumbersome to operate, takes a long time, and has a low yield of diosgenin. Moreover, due to the large volume of medicinal materials, the consumption of acid is large, and the organic matter degraded by acid is large, resulting in a large amount of sewage and large environmental pollution, which seriously hinders Development of Diosgenin Industry
Using gasoline or petroleum ether to extract the hydrolyzate requires a large amount, and 120# gasoline is a first-class explosion-proof solvent with a high risk factor

Abstract

The invention discloses a preparation method of a diosgenin chitosan carrier. The preparation method is characterized by comprising the following steps of: firstly, crushing rhizomes of dioscorea zingiberensis, fermenting the rhizomes with an enzyme, and performing ultrasonic extraction with lauryl sodium sulfate and magnesium chloride to obtain an ultrasonic extracting solution; and hydrolyzing the ultrasonic extracting solution with a small amount of sulfuric acid to obtain a diosgenin hydrolysate, separating out foam with a foam separator, flushing the foam with a phosphate buffer salt solution, enabling the foam to flow into a dry lipid membrane prepared from egg yolk lecithin and cholesterol to form a liposome suspension, finally performing ultrasonic treatment, performing microfiltration, and performing chitosan wrapping to obtain the diosgenin chitosan carrier. The diosgenin yield is high, the acid consumption is low, and the diosgenin chitosan carrier is high in encapsulation efficiency, good in stability, free of irritation to human skin, high in skin permeability and high in anti-inflammatory capacity, has an inhibiting effect on tyrosinase and is applicable to cosmetics.

Description

technical field [0001] The invention relates to the field of plant extraction, in particular to a preparation method of a diosgenin chitosan transfer body. Background technique [0002] Diosgenin, known as diosgenin in industry, is the ligand of diosgenin. It is connected to the sugar group through a glycoside bond at the C-3 position. It mainly exists in the rhizome of diosgenin in the form of diosgenin, and is closely connected with cellulose. bound in the cell wall. Diosgenin is an ideal precursor for the synthesis of various steroidal hormones and steroidal contraceptives. More than 60% of the steroidal hormones produced in the world are produced from it. At the same time, it also has the effects of hemolysis, blood fat reduction, anti-tumor, antibacterial and anti-inflammatory. There is a huge demand for diosgenin at home and abroad, so developing a new production process for extracting diosgenin has important value and broad market potential. [0003] At present, th...
