| Abstract: | Objective To optimize the extraction technology of sequoyitol in Nephrolepis Cordifolia.Methods An L9（34） orthgonal experiment was performed to investigate the 3 factors（3 levels for each factor were selected）,the chroma and dosage of ethanol,time of extraction with the sequoyitol as indexes for evaluation.Results The time of extraction had significant impact on the extraction of the effective components in Nephrolepis Cordifolia.The best extraction technology was as follows： adding 4 folds of ethanol solution for 3 times（at a concentration of 75%）for digeratur extraction thrice,3.5 h,2.5 h,and 2 h each time.Conclusion The optimized technology for the extraction of sequoyitol from Nephrolepis Cordifolia is stable,reasonable and feasible. |
