Leyla Polat Kose and her team also explored the antioxidant capacity of various phytolignans and mammalian lignans through ABTS + , DPPH, CUPRAC, and FRAP, discovering that phytolignans, as secondary metabolites in plants, demonstrated relatively high antioxidant activity, while enterodiols and enterolactones showed weaker activity compared to phytolignans and standard antioxidants (Polat Kose and Gulcin, 2021)
