Objective: To optimize the preparation process of inclusion complex of volatile oil from Acori Tatarinowii Rhizoma and hydroxypropyl-β-cyclodextrin (HP-β-CD). Method: Taking composite score of inclusion rate of volatile oil
yield of inclusion complex and the content of α-asarone as index
central composite design-response surface methodology was adopted to optimize inclusion process with inclusion temperature
reaction time
ratio of HP-β-CD and volatile-oil as factors. The quality of inclusion complex was evaluated by infrared spectroscopy (IR) and GC-MS. Result: The best process was as follows
inclusion time was 3.85 h
inclusion temperature was 30.06℃
ratio of HP-β-CD and volatile-oil was 8.69: 1. Under these conditions
inclusion rate of volatile oil was 79.74%
yield of inclusion complex was 87.47%
the content of α-asarone in inclusion complex was 2.266 mg·g-1. After inclusion
similarities of GC-MS spectra of volatile oil was high. Conclusion: The characterization results of IR and GC-MS proved the generation of inclusion complex. Central composite design-response surface methodology is suitable for optimizing inclusion process of inclusion complex of volatile oil from Acori Tatarinowii Rhizoma and HP-β-CD.
