چکیده
|
The aims of this study were to evaluate the effects of some extraction methods (ultra-sound: um,maceration: mm) and solvents (ethanol: eoh,methanol: moh) of the polyphenols,flavonoid contents and antioxidant activities from calligonum comosum. the eoh extracts contained high levels of polyphenols and flavonoids when compared to moh extracts. the ethanolic maceration method (eoh mm extract) had the highest antioxidant capacity (596.83 mg gae/g dried extract). also the eoh um extract showed higher capacity (511.22 mg gae/g dried extract),when compared to methanol extracts (275.41with moh mm and 231.59mg gae/g dried extract with moh um). the values of ic50 clearly indicated superiority of ethanol extracts (6.3 μg /ml for um and 7.9μg/ml with mm) to methanol extracts (50μg/ml for um and 100μg/ml with mm). apparently the extracts um showed good values compared to (mm) method it with two solvent.
