Abstract:
OBJECTIVE:To optimize the extraction technology of total saponins from Litchi chinensis.METHODS:The extraction technology of total saponins from Litchi chinensis was optimized by orthogonal experiment taking the content of total saponins and extraction rate as indexes with the extraction solvent,the amount of solvent,the extraction time and extraction times as factors. RESULTS:The optimal extraction technology of total saponins from Litchi chinensis was as follows:70% ethanol as solvent,1 g medicinal powder(per 8 mL solvent),extraction time of 1 hour (extraction for 1 time). CONCLUSION:The optimum extracting technology is simple,feasible and stable,and it provides theoretic basis for the further utilization of Litchi chinensis.
