[Abstract]
Objective To screen and optimize the matrix prescription of Vernonia anthelmintica cream. Method Heating white vaseline, liquid paraffin, and glycerol monostearate (GMS) in a 75 ℃ water bath until they are melted and mixed evenly as an oil phase. The effective fraction of V. anthelmintica (VAEP) was first moistened with polyoxyethylene 40 hydrogenated castor oil (RH40), and then added with water and diethylene glycol monoethyl ether (Transcutanol P) as the aqueous phase. The aqueous phase was heated in a water bath at 75 ℃, and then added in a thin stream to the oil phase, stirring while adding. After being taken out of the water bath, continue stirring until it was semi solid to obtain the cream. The weight coefficients of each evaluation index were determined using the Analytic Hierarchy Process (AHP) -Index Weight Determination Method Based on Index Correlation (CRITIC) hybrid weighting method, using the appearance characteristics, spreadability, centrifugal stability, and cold and heat resistance stability as evaluation indicators. The formulation of V. anthelmintica cream was optimized using the D-optimal mixture design. Prepare creams with different drug loads (1%, 2%, 4%, 8%, and 16%) according to the optimal prescription, and conduct comprehensive scoring. The cream with drug loading of 1%, 2%, and 4% was prepared and placed for 30 d at 4 ℃. The content change rate of vernonin and 3, 5-dicaffeoylquinic acid in the cream was preliminarily investigated by HPLC. Results According to AHP- CRITIC mixed weighting method, the weight coefficients of appearance characteristics, spreadability, heat and cold resistance stability, and centrifugal stability were 13.18%, 16.01%, 38.93%, and 31.89%, respectively. Combined with D-optimal mixture design, the optimal formulation of V. anthelmintica cream was determined to be liquid paraffin 10%, vaseline 45.48%, GMS 7.83%, RH40 10.31%, Transitol P 6.65%, and water 19.73%. The maximum drug loading of V. anthelmintica cream was 4%. The change rate of the content of vernonia macrocephalin and 3, 5-dicaffeoylquinic acid in the cream was less than 4.3% within 30 d. Conclusion The preferred V. Anthelmintica cream was uniform,translucent,delicate and soft,and easy to spread,with good stability,and the preparation process was stable and feasible.
