There are several published research papers that gives protocol for the analysis of free radical scavenging activity assay (as mentioned above). As per your lab set up and research objectives, you can go through aforesaid links and conduct the experiments.
You can detect melanin polymers with pyrolysis GC-MS. You can check the attached article. I have been looking for teams to collaborate on this issue for a long time. I wish you good luck.
