OBJECTIVE： To prepare zedoary turmeric oil compound liposomes （ZTOC-LPS） and evaluate its quality. METHODS： The preparation method of liposome， the addition amount of soybean phosphatidylcholine （SPC）， ratio of SPC to cholesterol （CH） in lipid， drug-lipid ratio of zedoary turmeric oil （ZTO）， drug-lipid ratio of tretinoin in formulation， and water bath temperature were screened using encapsulation efficiency and drug-loading amount of ZTO （represented by germacrone） and tretinoin as investigation indexes. Quality evaluation and primary stability investigation were conducted for liposomes prepared by optimal preparation technology. RESULTS： The optimal preparation method was ethanol injection method； The optimal preparation technology were SPC 4 mg in 1 mL lipid， the mass ratio of SPC to CH 3 ∶ 1， the ratio of ZTO to lipid 1 ∶ 9 ， the ratio of tretinoin to lipid 1 ∶ 70， water bath temperature of 55 ℃. Encapsulation efficiencies of ZTO and tretinoin were （64.63±1.00）％ and （90.33±0.72）％ in 3 batches of ZTOC-LPS， respectively. Drug-loading amount of ZTO and tretinoin were （9.09±0.14）％ and （1.43±0.02）％， respectively. Particle size was （257.41±7.58） nm， Zeta potential was （－38.77±0.81） mV， PDI was 0.10±0.04； the results of centrifugal acceleration test showed that the liposomes had good physical stability. No obvious change was found in each investigation index of ZTOC-LPS that stored at （4±2） ℃ for 1 month. CONCLUSIONS： Established preparation technology is simple and feasible， the quality of the prepared ZTOC-LPS conforms to the requirements， and it can provide reference for the following research of ZTOC-LPS.
