Abstract:
OBJECTIVE:To optimize the extraction technology of total lignans from pine needles of Cedrus deodara. METH-ODS:Using ethanol volume fraction,ratio of liquid to solid and extraction time as response factor,the content of total lignans as response value,the response surface methodology test was conducted based on Box-Behnken design to optimize the extraction tech-nology of total lignans from pine needles of C. deodara. RESULTS:The optimal extraction technology was as follows as ethanol volume fraction of 78%,ratio of liquid to solid 25∶1,extraction time 1.75 h. The content of total lignans from pine needles of C. deodara was 99.2 mg/g,which was close to predicted value 100.49 mg/g,with relative deviation of 0.65%. CONCLUSIONS:Op-timized extraction technology of pine needles of C. deodara by response surface methodology is feasible and stable,and has good predictability.
