2014/04/01
本研究分別以超音波萃取,管柱層析劃分及超臨界流體抗溶沉澱三種程序萃提與純化五味子果粒中五種五味子素。首先,以管柱層析法進行超音波乙醇萃取物(總濃度為26.14 mg/g)的劃分,可使劃分層內五味子素濃度提升10倍(總濃度為206.34 mg/g),接著以超臨界流體抗溶沉澱管柱劃分層可使五味子素濃度提升2.9倍(總濃度為 581.85 mg/g)。總回收率可達到84%。超臨界抗溶沉澱流出物內五味子醇乙含量達145.32 mg/g,五味子甲素含量56.65 mg/g,五味子乙素含量66.38 mg/g,五味子酯含量266.70 mg/g,五味子丙素含量46.80 mg/g。 This study examined ultrasonic agitation extraction coupled with elution chromatography and supercritical anti-solvent (SAS) precipitation to purify five lignans from dried fruits of Schisandra chinensis. Column fractionation of the ultrasonic ethanol extract resulted in a 10 times increment of those five lignans and supercritical anti-solvent precipitation of the column elution further resulted in 2.9 times increasing of the five lignans. Experiment data showed that concentration of five lignans enhances from 26.14 mg/g in the extract to 581.85 mg/g in the SAS effluent with a recovery of 84%. The elution contains schisandrol B of 145.32 mg/g, schisandrin A of 56.65mg/g, γ-schisandrin of 66.38mg/g, gomisin N of 266.70 mg/g and schisandrin C of 46.80 mg/g. Finally, experimental results from a response surface method designed SAS revealed that the SAS time and the carbon dioxide flow rate are significant in altering the purity and the recovery.
