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 quickly and efficiently separating and extracting effective components in traditional Chinese medicines, and a preparation method and application thereof. The magnetic nanocomposite material is applied to the extraction of cis-hydroxy or ortho-hydroxy sugar compounds in complex component systems such as traditional Chinese medicines In the separation system. Background technique [0002] Traditional Chinese medicine is a fundamental cure and longevity diet bestowed by nature to mankind. The basis of comprehensive cure of traditional Chinese medicine is the use of its complex effective chemical component system. [0003] In the traditional Chinese medicine industry, the most critical process is the extraction and separation of active ingredients. Traditional extraction and separation methods such as decoction, dipping, percolation, and reflux methods generally have low extraction of active ingredie...
