ORAC is a method of measuring antioxidant capacities in biological samples. It is mainly used in patients who are undergoing radiation therapy, to see if the radiation has caused the generation of harmful free radicals

There is a method developed by Jürgen Lademann, Charité. It works with Raman spectroscopy of the skin.

Thanks all for your valuable responsed

Dear Bashier Ibrahim Osman

We recently described a method for measurement of antioxidant capacity with great accuracy and precision based on KMnO4 reduction on the nitrocellulose membrane. The method is cheap and rapid. You can find the protocol here:
