ABSTRACT
Objective:
To optimize the water extraction and alcohol precipitation technology of Xuanfei Zhike granule .Methods:
Orthogonal test was used to investigate the effects of adding water , decocting time and boiling time on the water extraction , and the effects of relative density , alcohol precipitation concentration and alcohol precipitation time on the alcohol precipitation technology by taking comprehensive score including the amount of hesperidin , the amount of tectoridin and the yield of dry cream as the indices .Re-sultsThe preferred water extraction technology was as follows added 10 times water and extracted 1.5 h firstly, and then added 8 times water and extracted twice with 0.5 h for each.The preferred alcohol precipitation technology was as followsconcentrated the wa-ter extraction to a relative density of 1.05 (measured at 60℃), slowly added 95%ethanol to 80%alcohol solution and stored 18 h at low temperature .Conclusion:
The optimal water extraction and alcohol precipitation technology is stable and feasible , which can pro-vide reference for the standardized production of Xuanfei Zhike granule .
