METHOD OF SEPARATING AND PURIFYING BERBERINE ALKALOID

摘要

PURPOSE:To obtain in high purity berberine alkaloid, by treating tissue piece or cell of a plant with a specific alcohol to give an extracted solution, adding a specific salt exchanger to the solution to precipitate berberine alkaloid as a salt and separating berberine alkaloid. CONSTITUTION:Tissue piece of cell containing berberine alkaloid is treated with 2-4C aliphatic alcohol, the prepared extracted solution is incorporated with a salt exchanger containing chlorine ion and/or nitrate ion to precipitate berberine alkaloid as a salt, which is separated.
