[Study of microwave-assisted extraction on total flavones content in Hibiscus manihot L. flower].
OBJECTIVE
To study the extraction process of the total flavones content in Hibiscus manihot L. flower.


METHODS
it was investigated that effect of ethanol concentration, extracting time, power of microwave oven and Solid/Liquid ratio (g/mL) on total flavones content using the orthogonal design.


RESULTS
The optimum microwave-assisted extraction conditions included: ethanol concentration of 70%, extraction time of 30s, the power of microwave oven of 360w, solid/liquid ratio of 1 : 50 (g/ml) and granularity < or = 80 pore.


CONCLUSIONS
There are broad possibilities for the extraction of the total flavones content from Hibiscus manihot L flower using Microwave-assisted technigue.
