ABSTRACT
Objective: Using the improved volatile oil extractor to extract the essential oil of Caryophylli Flosand emulsified fragrance water. To research the correlations of the emulsified fragrance water from different condensing temperature and different temperature with the physicochemical parameters under the different temperature of essential oilin Caryophylli Flos;The results help a lot for the optimization of extraction process parameters of essential oil in Caryophylli Flos. Methods: Using surface tension tester, determination of viscometer to measure viscosity, surface tension, interfacial tension under different temperature of essential oil density in Caryophylli Flos, using stability analyzer to determine the emulsified fragrance water stability within 1 h and particle sizeunder different extraction temperature and different collecting temperature. Using multivariate data analysis to research the relationship between the essential physical and chemical parameters with emulsified fragrance water stability.Results: Relativedensity, viscosity, and surface tension reduced as the temperature of essential oil in Caryophylli Flos increased gradually, interfacial tension with increased first and then decreased as temperature increased. Turbiscan Stability Index(TSI) of the volatile oil emulsified fragrance water was negative correlation with the condensation temperature and interfacial tension, and was positive correlation with collecting temperature, density, viscosity, and surface tension. Conclusion: During the extraction process, temperature, interfacial tension, and condensation temperature of volatile oil in Caryophylli Floswere collected with aromatic water, and TSI hascertain relevance. Through controlling the collected temperature, condensation temperature, interfacial tension, and oil/water separation speed of volatile oil emulsified fragrance water have been changed and the guidance to the extraction process has been provided.
