Abstract:
OBJECTIVE: To optimize the preparation technology of Buqi tongmai capsule.METHODS: Orthogonal experiment of exeracting Radix Astragali was conducted with crude drugs soaking time,extracting times,amount of water added and decocting duration as factors and the content of astragaloside as index.Orthogonal experiment of exeracting Salvia miltiorrhiza,Ligusticum chuanxiong,Fructus Aurantii Immaturus,Carthamus tinctorius was conducted with crude drugs soaking time,amount of water added and decocting duration as factors and the content of tanshinol as index.RESULTS:Water was adopted for extraction and the concentration of alcohol for precipitate was 70 percent.The optimal technology of exeracting Radix Astragali was to soak the crude drugs for 30 min,decoct for 90 min in 10 times of water for 2 times.The optimal technology of exeracting S.miltiorrhiza,L.chuanxiong,Fructus Aurantii Immaturus,C.tinctorius was to decoct the crude drugs for 90 min,8 times of water for 2 times.CONCLUSION:The preparation processes is feasible,stable and meet the demands in the clinic.
