I found an IC50 of a plant extract in DPPH 6 µg/ml
but EC50 in reducing power 140 µg/ml.
I woundred to know if I make a mistake or there is a logic explanation?
Did you measure under exactly the same conditions (pH, solvent, T, etc)?
I measure it under the laboratory conditions .
thank you ,I understand your answer.
I use LoRa with Matlab/Simulink
