Alkaloids are nitrogenous organic compound from the plant kingdom。 They are very effective components in herbs。 But the extraction effect of alkaloids in the traditional silica or alumina chromatography is not ideal. Alkaloidal are usually extracted in the acid water of PH less than 3. The extraction of crude extract (60% purity) is by extract directly on the the SP cation exchange packings. Monomers are extracted with the SKP or SKR series of delicate filler separation and purification. SKP series packing, tolerance to acid and alkali, is more widely than traditional silica filler application range and longer life.
