3、io of Star anise oil in the inclusion complex was used as criterion in these experiments. The inclusion complex was made by pestling method. ResultsThe best conditions of the inclusion complex were that: the ratio of Star anise oil and -Cyclodextrin was 1:13.0(mL/g), and grinding for 4.0 hours at 35

4、.0. The ratio of volatile oil in the inclusion complex was about 81.4%, and the inclusion complex was identified by IR. ConclusionThe optimized process is stable and highly efficient.   Key wordsStar anise oil；-Cyclodextrin；  Inclusion process；Uniform design    Guangxi

5、is a Chinese autonomous province, located in a subtropical zone, south west of China. In particular, it has extensive resources of different plants. Among them, there is a special and commercial product, essential oil, which is widely recognized. Essential oils are the volatile, fragrant substances

6、residing in the flowers, fruits, leaves, and roots of many plants1.Most of them are a complex mixture of chemical constituents，including nitrogen and sulfur-containing molecules, aromatic chemicals, and terpenes    The following oils are the most famous and are found in large quantity

7、 in Guangxi. Eucalyptus oi1 has been employed in ointments as a topical counter-irritant and together with menthol as an inhalation1.Star anise oil is the main product in the fruits of Illicium verum. The plant contains remarkable essential oil, which is used as flavoring and medicine to control cau

However, the effectiveness decreases with long time storage, and both physical and chemical characteristics change

11、 relatively.-CyclodextrinX(structure above) has been of interest in numerous industries including the pharmaceutica1 field. This is due to their particular structures which impart interesting physiochemical properties. Today -CD is known for their ability to molecularly encapsulate a wide variety of

12、 the drugs into their hydrophobic cavity, resulting in the enhancement of water solubility and drug dissolution's rate1. The results of physi cochemical tests showed that after inclusion the solubility and stability of paprika pigment, the binding ability of -cyclodextrin for inclusion complex w
