The dynamic change of the total flavone content in Ophiopogon japonicus fruits was measured by the method of spectrophotometric colorimetry at 510 nm. The results showed a fluctuation in the increasing concentration of total flavone in Ophiopogon japonicus fruits with ripening, and two peak concentrations were detected. The main factors affecting the microwave-assisted extraction included the type of extracting solvents used and temperature, and pre-microwave treatments facilitated rapid extraction of total flavone.
