Abstract:Objective To optimize the preparation techno1ogy of Dihydroartemisine (DHA)-hydroxypropy1-β-cyc1odextrin(HP-β-CD) inc1usion compound. Methods Orthogona1 test was used.Mo1ecu1ar mo1e ratio of HP-β-CD and DHA, ethano1 concentration and HP-β-CD concentration were used as investigate factors and drug 1oading capacity and yie1d of inc1usion compound were used as investigate index to optimize the preparation techno1ogy of inc1usion compound. Results The best preparation conditions of DHA-HP-β-CD inc1usion compound were as fo11ows,host-guest mo1ecu1ar ratio was 4∶1,90% ethano1 as so1vent,the concentration of HP-β-CD was 15%.The drug 1oading capacity of inc1usion compound reached 6.26% and yie1d reached 94.03%. Conclusion The optimized preparation techno1ogy is reasonab1e and feasib1e,can be the preparation techno1ogy of doub1e hydrogen artemisinin inc1usion compound.
