【摘要】 [目的]探讨微波辅助提取印楝核中salannin的适宜条件。[方法]分别考察辐射时间、溶剂、物料比和辐射功率对salannin提取率的影响,以PHLC定量测定所萃取的salannin含量。[结果]最佳组合为以甲醇为溶剂,辐射时间3×3min,微波功率210W,物料比(g:ml)1:3;此条件下salannin的提取率为78.383%。[结论]与磁搅拌溶剂萃取法相比,微波辅助提取法不仅萃取产量高,而且萃取时间短。更多还原

【Abstract】 [Objective] Microwave assisted extraction (MAP) of salannin from Azadirachta indica was studied.[Method] The test was taken to investigate the effect of irradiate times,solvent system,solid-liquid ratio and irradiate power.The salannin contents were determined by PHLC quantitative.[Result] The better technological parameters were radiation time 3×3 min,microwave power 210 W,material ratio ( g/ml ) 1∶3,extraction rate of salannin at this condition was 78.383%.[Conclusion] The result showed that compared with the methods of conventional solvent extraction,microwave-assisted extraction not only provided higher production but also faster.更多还原
