Extraction of the Volatile Oil and Preparation ofβ-cyclodextrin Inclusion Compound of Yulianzhixie Pill

To study optimum inclusion process condition for volatile oils from Aralia Continentalis Kitag and heat stability,the ratio of the oil in inclusion compounds was used as criteria in the experiment,and the optimal process condition was given with the L_9(3~4)orthogonal experiment,meanwhile,the stability was tested at 60℃ in an oven.

Objective: To study optimum inclusion process conditions for volatile oils from Herba Schizonepetae and Pericarpium Citri Reticulatae Methods : The grinding method was compared with the saturated water solution method by determining the ultilization ratio of volatile oil from both herbs.

An index,based on the yield of inclusion and the utilization ratio of atractylon,was proposed to select an appropriate inclusion process.
