Abstract:
AIM: To optimize the best prescription of micro-emulsions of volatile oil in rhubarb of compound liquid spray by triangular phase diagram METHODS : Poloxamer-108 was used as emulsifiers,absolute alcohol as assistant emulsifiers,volatile oil from Lonicera dasystyla and Curcuma longa as the oil phase,the proportion between the emulsifier and append-emulsifier was established RESULTS : Optimized ratio of Poloxamer-108 and alcohol was 1∶10,the volatile oil in prescription formed micro-emulsions,distributing stably in the spray CONCLUSION : The study of micro-emulsions of volatile oil in compound liquid preparation of traditional Chinese medicine by triangular phase diagram offered a short-cut for resolving its stability. The experiment also suggested that the micro-emulsions could increase solubility of insoluble volatile oil from TCM.
