Novel rutin extraction technology

Abstract

The invention discloses a novel rutin extraction technology, comprising the following steps of: (1) allowing glue-removed Flos sophorae to automatically enter into a hopper; (2) allowing Flos sophorae to enter into a screw-type propeller and then enter into a countercurrent supersonic wave extraction pipeline, and allowing alkaline water to reversely enter into the countercurrent supersonic wave extraction pipeline for extraction; (3) allowing Flos sophorae which undergoes alkaline water immersion and extraction to enter into the countercurrent supersonic wave extraction pipeline for segmental extraction, followed by synchronous separation of an extract and herb residues; (4) carrying out first grade filtration on the extract; (5) carrying out second grade filtration on a first grade filtrate; (6) carrying out third grade filtration on the second grade filtrate, entering into a comprehensive regulating tank, adjusting pH to 1-5, followed by precipitation and crystallization; (7) allowing the herb residues which are swashed to automatically lift by an elevator into a herb residue squeezing machine, allowing the squeezed herb residues to automatically enter into the comprehensive regulating tank, followed by residue-liquid separation. (8) finishing the extraction. In comparison with the prior art, the novel rutin extraction technology provided by the invention allows continuous production with high level of automation, and can be adopted to raise the extracting purity and the extraction rate of rutin.

Description

technical field [0001] The invention relates to the field of rutin extraction, specifically a novel rutin extraction process. Background technique [0002] Rutin is a light yellow needle-like crystal (water) with a melting point of 176-8°C. It is clinically used to prevent and treat cerebral hemorrhage, hypertension, retinal hemorrhage, purple scar and acute hemorrhagic nephritis. It is also used as a food antioxidant and pigment . Its pharmacological action is: Rutin is a vitamin drug, which can reduce the permeability and fragility of capillaries, maintain and restore the normal elasticity of capillaries. The production process of rutin is mainly completed by alcohol extraction, extraction, chromatography, crystallization and other processes. However, the existing rutin extraction process has a low degree of automation, and the extracted rutin has low purity and low extraction rate, which needs to be improved. Contents of the invention [0003] In view of the above de...
