The extraction equipment ( Traditional Chinese medicine extraction equipment) The extraction of nystatin

The extraction of nystatin extraction equipment available ( Traditional Chinese medicine extraction equipment) With methanol, acetone and n-butyl alcohol polarity solvent extraction, the medium polarity solvent such as its solubility in butyl acetate is not big. PH without much effect on extraction, prefer to choose the best pH value on the stability of it, and do not choose to have the largest distribution coefficient of the pH value, generally in a neutral stability. The crude product selection precipitation: with polarity solvent such as formamide and dimethyl amide, dimethyl sulfoxide get concentrated solution, then add the low-level sex solvent precipitation.
