Problems solved by technology

The traditional acid hydrolysis method is cumbersome to operate, consumes a long time, and the yield of diosgenin is low
And because medicinal material volume is big, the consumption amount of acid is big, and the organic matter of acid degradation is many, causes sewage volume big, and environmental pollution is big, has seriously hindered the development of diosgenin industry
Use gasoline or petroleum ether to extract the hydrolyzate, and the dosage is relatively large
Moreover, 120# gasoline is a first-class explosion-proof solvent, with a high risk factor

Abstract

The invention discloses a production process for extracting sapogenin, which comprises the following steps: raw material pretreatment: fresh yam plants are depilated, washed to remove sediment, cut into sections with a thickness of 0.1 to 1 cm, and then washed with water. Separating starch and dioscin residues; solvent extraction: collecting dioscin residues, obtaining dioscin through solvent extraction; hydrolyzing dioscin; extracting, purifying, and recrystallizing the hydrolyzate. Adopting the production process of diosgenin of the present invention can solve the current problems of acid hydrolysis and gasoline extraction waste and environmental pollution, and can recycle medicinal dregs, and improve the extraction rate and purity of extracted diosgenin.

Description

technical field [0001] The invention relates to the technical field of extracting diosgenin, in particular to a production process for extracting diosgenin. Background technique [0002] my country is a big country of yam planting. The rhizome (turmeric) of the perennial herbaceous plant Dioscorea (D.zingiberensis) and the rhizome (D. nipponica) of the genus Dioscorea (D. nipponica) are the two species with the highest diosgenin content in my country, followed by Huangshan Medicine (D.panthaica), Chaihuangjiang (D.nipponica), Triangle leaf yam (D.deltoidea), etc. These plants are easy to grow and have a large annual output, so they have become the most important traditional Chinese medicine raw materials for the production of diosgenin in the industry. 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, an...
