Objective: A comparative study on inclusion effect of purity gum and β-cyclodextrin(β-CD). Method: With inclusion rate of volatile oil and yield of inclusion complex as indexes

purity gum and β-CD as inclusion materials

four kinds of inclusion technique were adopted to inclusion of volatile oil from Notopterygii Rhizoma et Radix

Forsythiae Fructus and Magnoliae Flos

inclusion process was optimized by single factor test

differential scanning calorimetry (DSC) and infrared spectrum was used to characterize technology of inclusion complex. Result: Inclusion rate of purity gum was significantly higher than β-CD

but recovery of inclusion complex of purity gum was slightly lower than β-CD.DSC diagram of purity gum inclusion curve did not appear characteristic peaks of volatile oil showed that oil has been involved.Maximum absorption peak of purity gum inclusion in infrared spectrum graph with respecting to purity gum have migrated to high frequency

it showed purity gum inclusion was a new biological phase

and inclusion effect was stable. Conclusion: Taking purity gum as inclusion material

magnetic stirring method for inclusion technique to prepare inclusion complex

not only process is simple

and has good effect of inclusion.
