Abstract

The invention relates to a magnetic nanocomposite as well as a preparation method and an application thereof. The magnetic nanocomposite is characterized by being modified with a Fe2O3 layer with a hydrothermal method and is regular in morphology and uniform in distribution. The magnetic nanocomposite has good magnetic responsibility and specific recognition capacity, can be applied to various fields such as a medicine purification system, extraction and separation of effective components, food processing, cosmetics, chemical separation and analysis and the like, can be particularly applied to a complicated component system such as Chinese herbal medicines and the like and has potential industrial production and application values.

Description

technical field [0001] The invention relates to a magnetic nanocomposite material for rapidly and efficiently separating and extracting active ingredients in traditional Chinese medicines and its preparation method and application. The magnetic nanocomposite material is used in the extraction of cis-hydroxyl or o-hydroxyl sugar compounds in complex component systems such as Chinese medicinal materials in the separation system. Background technique [0002] Traditional Chinese medicine is a cure-all medicine and life-prolonging diet bestowed by nature on human beings. The basis of comprehensive treatment of traditional Chinese medicine is to use its complex and effective chemical component system. [0003] In the traditional Chinese medicine industry, the most critical process is the extraction and separation of active ingredients, and traditional extraction and separation methods such as decoction, dipping, percolation, reflux, etc., commonly exist in the extraction of activ...
