This study was designed to comparative evaluate total flavonoid contents (TFC) in leaf, aerial root, twig, root and bark parts of Ficus microcarpa L.f. (Moraceace). Ultrasonic-assisted extraction was adopted using benign solvent: ethanol and water to determine the extraction efficiency under the condition of ethanol concentration 40%, solid/liquid ratio of 1:25, extraction time 35 min and extraction temperature at 60 °C. According to the experimental results, the TFC values varied considerably and the extraction yield of 2.67±0.02%, 3.70±0.043%, 2.99±0.04%, 6.56±0.83% and 4.26±0.18% were obtained from different parts, respectively. The root part was characterized as containing a high amount of flavonoids, which might be the active compounds responsible for the pharmaceutical properties of the plant. The study offers theoretic basis for further utilization of the traditional folk herb F. microcarpa.
