Study on Optimized Extraction of Fructus Schisandrae Chinensis / 中国药房

ABSTRACT

OBJECTIVE: To optimize the extraction process of Fructus Schisandrae Chinensis. METHODS: Taking the contents of schizandrin, schisantherin A, deoxyschizandrin, r-schizandrin as the indexes, the influence on the extraction process by extract solvent and medicinal material particle diameter was examined, and the extraction parameters were optimized. RESULTS: Active components of Fructus Schisandrae Chinensis, after the medicinal material being crushed, can be effectively utilized through extracting by alcohol. The optimized extraction parameters were as follows: the medical material being ground into 40 meshes, extracted twice by 70% alcohol, 2 hours per time. CONCLUSION: The optimized extracting process works better than current technique adopted for formulated granule preparation, and can ensure quality to the highest degree.
