OBJECTIVETo prepare the submicron emulsion of fresh Zhongjiefeng volatile oil.
METHODThe Zhongjiefeng volatile oil submicron emulsion was obtained after passing the elementary emulsion through a high pressure homogenizer. The physical and chemical stability of the emulsion was evaluated with the stability parameter of centrifugation, appearance of emulsion and the pH. The formulation and processing factors were optimized by single factor reviewing and orthogonal experimental design.
RESULTBy controlling various processing factors and optimizing formulation, the stable submicron emulsion of Zhongjiefeng volatile oil was prepared. Its mean particle diameter was 164-169 nm with PDI 0.084-0.107 and Zeta electric potential was -40 mV.
CONCLUSIONThe formulation and preparation technique of the emulsion is reasonable.
