tell me please how to calculate percentage inhibition of scavenging activity in ABTS method? % Inhibition = [(AbsControl – AbsSample)/AbsControl] × 100
here i dont know which value should i consider for AbsControl
because after dilution absorbance should b 0.700 but know values of my extract is 0.2727... if i consider 0.700 than all my values are in negative form
