Extraction and Inclusion Technology of Volatile Oil from Aifu Nuangong Capsule

Objective:To optimize extraction and inclusion technology of volatile oil from Aifu Nuangong capsule.Method:With soaking time,extraction time and the amount of water as investigating factors,yield of volatile oil as index,orthogonal test was used to optimize extraction technology of volatile oil.With ratio of volatile oil-cyclodextrin,inclusion temperature and inclusion time as investigating factors,composite score of inclusion yield and inclusion ratio as index,orthogonal test was used to optimize inclusion technology of volatile oil,and inclusion compound was identified.Result:Optimized extraction technology was:powder was soaked 1 h with 8 times the amount of water,extracted 7 h.Optimized inclusion technology was:ratio of β-CD and volatile oil was 8∶ 1,inclusion temperature was 50 ℃,inclusion time was 1.0 h.Conclusion:This optimized technology was feasible with high yield,it could be suitable for large-scale production.
