ABSTRACT

Objective To studyeffect of different processes for preparation ofβ- cyclodextrin inclusion pericarpium citri reticulatae - Radix Aucklandiae essential oil.Methods Extract pericarpium citri reticulatae-radix aucklandiae essential oil with steam distillation method, conductβ- cyclodextrin inclusion of pericarpium citri reticulatae-radix Aucklandiae essential oil with ultrasonic method, grinding method andsaturated aqueous solution method, and detect inclusion effect respectively by polarized light microscopy observation method and TG-DTA analysis method.Results Polarized lightphenomenon disappears under a microscope for the three inclusion preparation products, and TG-DTA curve of ultrasound method is superior to that of saturated aqueous solution method and grinding method.Conclusion Polarized light microscope observation method and TG-DTA method enjoysa good effect in determination of cyclodextrin inclusion, which provides a new method for determination of cyclodextrin inclusion results.
