ABSTRACT
Objective To optimize the extracting process of alkaloid from Nelumbo nucifera leaves by multi-stage countercurrent extraction.Methods The spectrophotometry was used to determine the alkaloids.The extracting process of alkaloid was optimized by L16(44) to observe the effect of extraction time,extraction temperature,solid to liquid ratio,and ethanol concentration,respectively.Results The optimum extraction parameters were extraction time 25 min,extraction temperation 90 ℃,solid to liquid ratio 1∶50,and ethanol concentration 70%.Conclusion The multi-stage countercurrent extraction is used to the extracting process of alkaloid from N.nucifera leaves.
