Özet:

 

Algae contain a large amount of biological active compounds functioning as antioxidant,  antimicrobial and anti-tumour. In the present research, antioxidant activity of freshwater alga Microspora sp.  Chlorophyta  extract prepared in different solvents  methanol, acetonitrile, ethanol, acetone and ethyl acetate  was determined with three different methods; 2,2-diphenyl-1-picrylhydrazyl  DPPH• , Iron  III  Reduction / Antioxidant  Power  FRAP  Assay and Copper  II  Reductive Antioxidant Activity  CUPRAC . The  alga samples collected from the high mountain lake  2733 m above sea level  localized in  Gümüşhane province of Turkey. The algal extracts prepared in different solvents showed  antioxidant activity. The values of DPPH• varied from 8.97%  in acetonitrile extract  to  31.15%  in methanol extract . As in the DPPH• method, the lowest and highest values in  the FRAP method were measured based on μM TEAC  Trolox Equivalent Antioxidant  Capacity  in methanol and acetonitrile extracts as 60.303 μM and 359.394 μM respectively.  While the lowest value of CUPRAC test was determined in acetonitrile extract  0.041 μM  TEAC   as in the other tests, highest value was measured in ethanol extract  0.101 μM  TEAC  . The values of highest antioxidant activity in both DPPH• and FRAP methods  was measured in the methanol solvent whilst was determined in the ethanol solvent for  CUPRAC.
