Adas (Foeniculum vulgare)

The main secondary metabolites found in Foeniculum vulgare are anethole, dianethole, fenchone, trans-anethole, quercetin, and kaempferol (Rather et al., 2016; Ben Abdesslem et al., 2021). The use of fennel in the health sector is related to its high content of organic acids, protein, choline, trigonelline, and antioxidants in the form of flavonoids (Badgujar et al., 2014).

The antioxidants found in fennel fruit are flavonoids, which have inhibitory effects on free radical production and possess free-radical-scavenging activity. Fennel fruit (Foeniculum vulgare) has the potential to act as a gastroprotective agent due to its high antioxidant content, particularly its flavonoids.
