ABSTRACT
Objective: To optimize the including preparation for peppermint oil-β-cyclodextrin polymer (β-CDP) microsphere inclusion compound. Methods: Peppermint oil-β-CDP microsphere inclusion compound was prepared by using co-precipitation. The preparation process was optimized through the L9(34) orthogonal test design and regression analysis. Peppermint oil-β-CDP microsphere inclusion compound was characterized by infrared (IR) spectroscopy, thermogravimetric analysis (TGA), and X-ray diffraction (XRD). Results: The best technological condition was A 2B2C1D3, and the order of the influence factors was the proportion of β-CDP microsphere and water > the percentage of peppermint oil in β-CDP microsphere > inclusion temperature > inclusion time. The formation of peppermint oil β-CDP microspheres inclusion compound was proved by the results of IR, XRD, TGA analyses. Conclusion The method is reasonable and feasible.
ABSTRACT
Objective: To study the optimized technology of inclusion for the volatile oil of Caryophylli Flos with β-cyclodextrin polymer (β-CDP) microsphere. Methods β-CDP Microsphere was prepared by saturated peroxide solution. The study was carried out with uniform design to optimize the best inclusion processing conditions and inclusion compound was to characterize its structure. Results The best condition of the optimized technology of inclusion for the volatile oil of Caryophylli Flos with β-CDP microsphene was as follow: the volatile oil of Caryophylli Flos (mL)-β-CDP microsphere (g) was 1:1; inclusion temperature was 35°C; clathration time was 1 h; ethyl alcohol could be ignored. The package method is successful by characterizing structure. Conclusion: The inclusion compound of β-CDP has high rate and the inclusion process is reasonable and feasible.
