| Abstract: | Objective To optimize the conditions for the extraction of the total flavones of Abelmoschus manihot by maceration.Methods The influence factor of maceration including immersion time,extracting times,ethanol concentration and solvent amount have been examined using the content of total flavones and hyperin as indexes.Extraction effects of the two methods which included maceration and circumfluence have also been compared.Results The optimum extraction condition was： Abelmoschus manihot meal was immersed with 30 times amount 60% ethanol for 2 hours,and was stirred one time every 30 minutes.Conclusion This method can be used in the extraction of total flavones of Abelmoschus manihot. |
