Extracting technology of total flavones in powder of Fagopyrum tataricum stem and leaf by enzymatic treatment / 中草药

ABSTRACT

Objective To optimize the extracting technology of total flavones in powder of Fagopyrum tataricum stem and leaf by enzymatic treatment. Methods The powder was treated by cellulase before extracted using water, the effects of enzyme dosage, treatment temperature, treatment time, and pH value on the extract rate of total flavones were studied. Results The optimum extracting technology was as follows enzymatic treatment temperature 55℃, enzyme dosage 3.0 ?L, pH value 6.5, treatment time 90 min, extracting 3 times at 90℃ for 30 min once. The extract rate of total flavones was 1.47% by this technology. Conclusion Cellulase could be applied in the assisstant extraction of total flavones in powder of F. tataricum stem and leaf.
