Gentiana lutea  is a wellknown and respected medicinal plant that is used in many pharmacopoeias, mainly against different gastrointestinal disorders. The plant is under protection regimes in its natural habitats and for that reason is grown on plantations. In addition, it could be cultivated  in vitro . The plants grown on plantation and in  in vitro  conditions were used to prepare methanolic and 50% ethanolic extracts of root and leaf/shoot, which were tested for antigenotoxic and antibacterial properties, against foodborne mutagens (heterocyclic aromatic amines PhIP and IQ) and food contaminants, respectively. The results obtained pointed out the excellent genoprotective effect (up to 78% inhibition of PhIP/IQ genotoxicity) based mostly on the antioxidative potential. The antibacterial effect was mainly weak; only the extracts of  in vitro  grown plant induced moderate activity against  Listeria monocytogenes  and  Staphylococcus aureus  (MICs ranged 0.15-5 mg/ml). In addition, the extracts’ potential to prevent biofilm formation by  L. monocytogenes  was very high (up to 90% inhibition). Taken together, the results obtained encourage further research that would be directed to the formulation of potent antigenotoxic and antibiofilm agents based on  G. lutea .

Can yellow gentian (Gentiana lutea) be useful in protection against foodborne mutagens and food contaminants?
