To optimize the extraction and inclusion technology of the mixed volatile oil of Foshou(Citri Sarcodactylis Fructus),Xiangyuan(Citri Fructus),Chenpi(Citri Reticulatae Pericarpium)and Bohe(Menthae Haplocalycis Herba).
Under the guidance of the quality by design concept,the key process parameters of volatile oil extraction were qualitatively and quantitatively screened using fishbone diagram,failuremodel and effect analysis respectively,and the extraction process of mixed volatile oilwas optimized using single factor test combined with Box-Behnken response surface test. The extraction rate,contents of D-limonene,γ-terpinene and L-menthol of volatile oilwere scored by Analytic Hierarchy Process(AHP)-entropy weight method,and the space of extraction process design was established. Single factor testand orthogonal testwere used to optimize the inclusion process of volatile oil and characterize its inclusion compounds.
The extraction time,water adding ratio and soaking time were the key parameters,and the extraction time was4.5-5 h,water adding ratio was 8.8-10 times and soaking time was 44-60 min. The optimal process of inclusion of volatile oil included the inclusion time of2.5 h,the ratio ofβ-cyclodextrin to volatile oil of12∶1 g/mL and the inclusion temperature of30℃.
The extraction and inclusion process of the volatile oil from the mixture of Foshou(Citri Sarcodactylis Fructus),Xiangyuan(Citri Fructus),Chenpi(Citri Reticulatae Pericarpium)and Bohe(Menthae Haplocalycis Herba)is stable and reliable based on the quality by design concept and AHP-entropy weightmethod,which provides an experimental basis for the subsequent development and industrial production of related preparations.
