@@@@To optimize the including preparation for essential oil of Osmanthus fragrans with β-cyclodextrin,the inclusion rate of essential oil was used to evaluate the technologies based on orthogonal design,in which the proportion of essential oil of Osmanthus fragrans and β-cyclodextrin,the inclusion temperature,the inclusion time,and the proportion of essential oil and solvent ethanol were used as four main technology factors. The inclusion compound was proved by infrared chromatography. The optimum preparation conditions for inclusion were established:essential oil of Osmanthus fragrans∶β-cyclodextrin=1∶ 8,the inclusion temperature=50 ℃,the inclusion time=2.5 h,and essential oil of Osmanthus fragrans∶solvent ethanol=1∶2. The method can be used for the preparation of essential oil of Osmanthus fragrans and β-cyclodextrin inclusion compound with saturated solution,which was reliable and convenient.
