Process for extracting saporin by direct separation method

Abstract

The invention refers to a method for extracting saponin from brown Windsor, the character is: it is accomplished by following steps: 1) crush: the brown Windsor is crushed and washed, it is crushed to 60í½100 items with water; 2) separation: a. fiber separation, sifts the crushed brown Windsor, separates the fiber with 110í½130 items sieve rotating vane pressure filter; b. adds CaO to the compound in 10í½25íµ, deposits for 2í½4 hours, the compound is divided into upper and lower two layers, the upper layer is saponin compound, the lower layer is starch, separates out the starch; 3) saponin extraction: acid hydrolysis, cleaning, drying, then extracts with 120 number gasoline or alcohol or acetone or the above-critical CO2.

Description

technical field [0001] The invention belongs to the field of phytochemical engineering, and in particular relates to a process for extracting saponin from turmeric. Background technique [0002] (1) Industrial background of saponin extracted from turmeric [0003] Yellow ginger, also known as yam, is a unique species in my country. It is a wild herbaceous vine of the genus Dioscrea (Dioscrea. L). Its rhizome contains a certain amount of dioscin and its hydrolyzed product diosgenin. Diosgenin is commonly known as diosgenin. This compound has hemolysis, blood lipid lowering, antibacterial, anti-inflammatory and other effects. It is an important pharmaceutical and chemical raw material for the synthesis of steroid hormone drugs and steroidal contraceptives. Steroid hormone drug applications It is widely used in the treatment of rheumatoid arthritis, cardiovascular and cerebrovascular diseases, etc. Steroidal contraceptives play an important role in the implementation of the bas...

AI Technical Summary

Problems solved by technology

[0007] (1) The production process is backward, and the recovery rate of saponin is low, generally below 85%.

[0008] (2) The degree of resource utilization is low, 50% of fiber and 40% of starch in turmeric (dry weight) are not recycled

Some enterprises have also made resource utilization attempts, but because the key technologies have not been resolved, no enterprise can achieve a high degree of resource utilization

[0009] (3) Serious pollution

[0010] Judging from the current situation, acid hydrolysis wastewater in turmeric processing is as difficult to treat as papermaking wastewater

At present, there is no enterprise that can meet the standard (first-level) discharge of wastewater after treatment in industrial production. Many enterprises have spent money to install equipment, but they can only be used for "comfort" and "demonstration students".

[0011] (4) A large amount of gasoline is used in the production process, which is flammable and explosive

[0012] (5) High labor intensity and high cost of production

[0015] At present, there are studies on the method of directly extracting saponin from turmeric with ethanol and acetone, but because of the low recovery rate and poor quality of saponin, it cannot be applied, and it is still in the research stage
