Objective To investigate the preparation of 1′-acetoxychavicol acetate (ACA) submicron emulsion and its properties. Methods ACA submicron emulsion was prepared using high pressure homogenization technique. The formulation and preparation technique were optimized, the particle size, Zeta potential, content, and stability were tested. Results The mean diameter and Zeta potential of ACA submicron emulsion were (175.03 ± 4.28) nm and (?30.80 ± 0.44) mV, respectively. The loading drug amount is about 877.3 μg/mL with a good stability when stored in low-temperature and away from light. Conclusion The prepared ACA submicron emulsion has a small size particals, high content, and good stability. This method can provide some basis and study on preparation of ACA.
