Abstract

The invention discloses a production process for extracting diosgenin. The production process comprises the following steps: pretreatment of raw materials: removing hairy roots of fresh dioscorea opposita plants, cleaning to remove silt, cutting into sections with a thickness of 0.1-1 cm, cleaning with water, and separating starch from dioscorea opposita residues; solvent extraction: collecting the dioscorea opposita residues, and performing solvent extraction to obtain dioscin; hydrolyzing the dioscin; and extracting, purifying and recrystallizing the hydrolysate. The production process can solve problems of waste and environmental pollution in the current acid hydrolysis and gasoline extraction, and can recycle residues, and improve extraction rate and purity of diosgenin obtained by extraction.

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...
