Abstract

The invention provides a method for purifying troxerutin from troxerutin industrial decoction dreg. The method comprises the steps that a separated material is pretreated and loaded into a chromatographic column; the troxerutin industrial decoction dreg is dissolved with water, stands and is filtered; filter liquor is sampled, adsorbed and eluted, eluant is concentrated and dried to obtain troxerutin, the content is 80% (HPLC detection), the recovery rate is 80%, and an obtained product meets the oral liquid standard of Chinese pharmacopoeia in 2015 version. Waste resources of synthetic drugs are effectively utilized, regeneration value of troxerutin is improved, and the method is fast, simple and suitable for industrialized production, and has an application prospect in the aspect of recycling troxerutin waste liquor.

Description

technical field

[0001] The invention relates to raw materials, in particular to a method for purifying and extracting troxerutin from troxerutin industrial dregs. Background technique

[0002] Troxerutine Chinese aliases: hydroxyethyl rutin, toxerutin, trihydroxyethyl rutin, Weinaolutong, vitamin P4, English name: Troxerutine. This product is soluble in water, soluble in methanol and ethanol, insoluble in chloroform. Molecular formula: C 33 h 42 o 19 , molecular weight 742.68. This product can inhibit the aggregation of red blood cells and platelets, prevent thrombus formation, and at the same time increase the oxygen content in the blood, improve microcirculation, and promote the formation of new blood vessels to enhance collateral circulation. It is suitable for hemiplegia and aphasia caused by cerebral thrombosis and cerebral embolism, as well as pre-myocardial infarction syndrome, arteriosclerosis, central retinitis, thrombophlebitis, varicose veins, and edema cause...
