Study on the Extraction of Volatile Oil of Xiangfu and Rougui and its Inclusive Compound in Fufangxiaojingtong Capsules
Abstract:ObjectiveTo study the optimum extraction process of volatile oil of Xiangfu and Rougui and its inclusive compound by Betacyclodextrin(βCD) in Fufangxiaojingtong(FFXJT) Capsules. MethodsThe effects of water content, soaked and distilled time on extraction of volatile oil were investigated and the technological process of inclusion compound by βCD were evaluated by orthogonal design. ResultsThe optimum extracted conditions were to add ten times amount of water into the mixture of crude drugs, to soak for 12 hours and to distill 8 hours. The optimum conditions of preparation of inclusive compound were the proportion of 1∶6 (volatile oil and βCD),3 hours of inclusion and ordinary temperature. ConclusionThe above technological process is the most rational.
