Abstract

The invention discloses a method for preparing a flavanone glycoside compound by using an industrial chromatographic technology, which comprises the following steps: taking a sample solution of a total flavonoid glycoside extract as a raw material, purifying by using an industrial chromatographic technology dynamic axial compression column system, and detecting the separation condition by using a dual-wavelength ultraviolet online detector, and according to the appearance time and the chromatographic peak height of the shaddock peel rutin component, collecting the eluent of the prepared flavanone glycoside compound with the collection starting and ending time of 155-235 min, and concentrating and drying the eluent. The purity of the prepared flavanone glycoside compound is relatively high; and the method has the characteristics of good process reproducibility, simplicity in operation, short preparation time, less organic solvent dosage, economy, environmental protection, large-scale industrial production and the like.

Description

technical field [0001] The invention belongs to the technical field of separation and purification of active ingredients of traditional Chinese medicines, and in particular relates to a method for preparing dihydroflavone glycosides by using industrial chromatographic technology. Background technique [0002] Naringe rutin is a kind of dihydroflavonoid glycosides. According to literature reports, it is widely found in traditional Chinese medicinal materials such as Fructus Aurantii Fructus, Citrus Aurantium, Changshan Huyou, Huazhou Pomelo, Huajuhong, etc. Huaqi Tablets, Chenxianglu Bailu Tablets, Xiaoer Fupi Granules, Weisu Granules, Zhishi Xiaopi Pills, Huoxiang Zhengqi Oral Liquid and other dozens of Chinese medicine varieties are used as active ingredients or representative ingredients for quality control. However, the research on low-content components such as naringel rutin is not enough, and due to the low content of this component and the cumbersome and complicated s...
