چکیده
Free radicals are unstable molecules caused by several electrons in the molecule that does not have a partner. can potentially trigger onset of various degenerative diseases. One efforts be made to ward off disease is consuming antioxidant compounds. Antioxidant compounds found plants with genus Allium, such as Allium cepa L. This study aims determine activity, flavonoid concentration, and phenolic concentration L extract. The DPPH method (2-2-diphenyl-1-picryhydrazil) used calorimetrically determined consensuality AlCl3, Follin-ciocalteu consensual sample. multilevel maceration sample extraction uses different polarity solvents, dichloromethane, ethyl acetate, 96% ethanol. Based on research data, were ethanol extract but dichloromethane acetate extracts found. 4,125 mgQE/gr Phenolic was 1,071 mgGAE/gr IC50 value which 201,221 ppm. These results show activity classified moderate, values being between range 100-250

AIM To investigate the antioxidant potential of two Allium cepa L. extracts. MATERIAL AND METHODS The antioxidant activity of the two extracts (encoded EC1 and EC2) was assessed using two methods: DPPH (2,2-diphenyl-1-picrylhydrazyl) scavenging capacity and determination of their reducing power; phytobiological, studies were performed using grains of Triticum aestivum L., Falmura variety. R...
متن کاملDetermination of antidiabetic activity in Allium cepa (onion) tissue cultures.
Seedling, seedling parts and callus cultures of onion were tested for their antidiabetic activity by feeding the tissue-extracts to diabetic rats. The results indicated much higher antidiabetic activity in callus cultures as compared to natural bulbs of onion. These results may be of pharmaceutical significance since the callus can be used as an alternative source for the isolation of antidiabe...
