The separation and purification process of medicinal excipient cyclodextrin (usually referring to β-cyclodextrin) is a multi-step procedure aimed at ensuring its high purity and stability as a medicinal excipient. 

Raw material preparation 

Fermentation and Extraction 

Purification process 

Drying and Packaging 

The separation and purification process of medicinal excipient cyclodextrin involves multiple steps such as raw material preparation, fermentation and extraction, purification, drying and packaging. By strictly controlling the parameters and conditions of each step, it is possible to ensure that the final cyclodextrin product obtained has high purity and stability, meeting the requirements of medicinal excipients.
