【Abstract】 Objective: To compare the extraction efficiency of imperialine extracted with different solvents. Methods: The content of imperialine in the extracts was determined by thin layer chromatography scanning. Results: Among the methods suitable for alkaloid extraction, the solvent ether chloroform 95% ethanol (25∶8∶2.5) is the best for imperialine extraction. Conclusion: The imperialine extraction efficiency is greatly affected by the extraction solvent.更多还原
