Peanut is a potent natural source of phytochemical compounds and is associated with human health. In the present study, we determined the biological activity and chemical constituents of peanuts germinated for 0-9 days. The ungerminated seed coat exhibited the highest antioxidant potential, phenolic compound content and anti-inflammatory activity. During the germination process, on the first germination day, root extract showed the highest antioxidant potential, phenolic compound content and anti-inflammatory activity. The kernel exhibited a low phenolic compound content and antioxidant activity at the early stage of germination and significantly increased after 9 days of germination. Resveratrol increased to 7.19 ± 0.07 µg/g dry weight on the second day of germination. LC-MS/MS showed a variety of phenolic compounds and stilbene derivatives in different parts of germinated peanut. These results suggest that the peanut sprout exerts high anti-inflammatory effects that may be related to the polyphenolic content and antioxidant properties.
