Abstract

The invention discloses a method of separating epivogeloside from iridoids in extracts of honeysuckles through cation exchange resin, wherein the method includes the steps of: a) soaking the cation exchange resin with an ethanol solution being 20% in volume fraction for packing a column; b) packing the treated cation exchange resin treated in the step a) as a filler in the chromatographic column; c) with an equilibrium liquid, equilibrating the chromatographic column for loading the sample; d) dissolving a crude product of a honeysuckle extract in deionized water to prepare a honeysuckle extract solution; e) injecting the honeysuckle extract solution into the chromatographic column; and f) eluting the target substance from the chromatographic column with an eluent. The method is simple in operation, is less in energy consumption, is short in time consumption, is low in cost and is high in purity. The method overcomes the defects of complex steps and operations, high cost, low yield and low purity of a conventional process.

Description

technical field [0001] The present invention relates to a method for separating epibroken loganin hemiacetal lactone from iridoids of honeysuckle extract, in particular to a method for separating epibromologin hemiacetal lactone from iridoids of honeysuckle extract by using cation exchange resin The method for qianziside hemiacetal lactone belongs to the technical field of purification in the pharmaceutical industry. Background technique [0002] Honeysuckle, also known as honeysuckle, contains chlorogenic acid, luteolin, iridoids and other pharmacological active ingredients, which are effective against hemolytic streptococcus, staphylococcus aureus and other pathogenic bacteria and upper respiratory tract infection pathogenic viruses. Strong inhibitory power, in addition, it can also enhance immunity, anti-early pregnancy, protect the liver, anti-tumor, anti-inflammatory, antipyretic, lower blood sugar, stop bleeding (coagulation), inhibit intestinal absorption of cholester...
