| Abstract: |
| OBJECTIVE To optimize the water-extraction of polysaccharide from Herba Ecliptae. METHODS With the extraction rate and contents of polysaccharide as the index, orthogonal test was used to evaluate the extraction. RESULTS The optimal condition was added 10 times water for 3 times and 3.5 hours for each time at the temperature of 100 ℃. In this condition, the extraction percent of polysaccharide from Herba Ecliptae was 11.39% and the content was 18.43%. CONCLUSION The optimized extraction is stable, economical and feasible. |
