1. Introduction 

Bestdex LH-20 is modified with hydroxypropyl on the basis of dextran gel Bestdex G-25.The introduction of hydroxypropyl makes the resin both hydrophilic and lipophilic. Organic solvents can be used as mobile phase. It is suitable for separation and purification of active ingredients in traditional Chinese medicine as well as fine purification of antibiotics and chemical drugs. The resin combines the characteristics of gel filtration, distribution chromatography, and adsorption chromatography to separate molecules with very similar structures.
