Abstract:
Objective: To optimize the preparation process of volatile oil prepared from the aerial parts of Houttuynia cordata (Houttuynie Herba, HH)-β-cyclodextrin (β-CD) inclusion complex by central composite design-response surface method. Methods: To prepare the inclusion complex by stiring, with the overall desirability (OD) values of inclusion ratio, yield of the inclusion complex, and methyl-n-nonyl-ketone content as indexes, the influence of inclusion temperature, inclusion time, and ratio of β-CD-HH volatile-oil to inclusion process was investigated by response surface method, the results were fitted by multi-linear equation and second-order polynomial equation, and the optimal inclusion process was predicted according to formulation. The quality of inclusion complex was evaluated by IR and HS-SPME-GC-MS. Results: The optimal inclusion technologies of the HH volatile oil-β-CD inclusion complex were as follows: inclusion time 4.8 h, inclusion temperature 62°C, and ratio of β-CD-HH volatilel oil 7.79:1. Bias of inclusion ratio, yield of the inclusion complex, and methyl-n-nonyl-ketone content between observed and predicted values were 1.70%, 1.49%, and 2.22% respectively. Conclusion: Using the central composite design-response surface method to optimize the preparation of HH volatile oil-β-CD inclusion complex has a good prediction.
