From the Leaves of Viburnum tinus L. four metabolites viz viburtinoside A and B (acylated iridoid glucosides), scopoletin 7-O-β-d-sophoroside and natural occurred 2,6-di-C-methyl-nicotinic acid 3,5-diethyl ester with 10 known metabolites were isolated. Toxicity and CCl4-induced hepatotoxicity of the investigated extract have been evaluated in terms of the determination of ALT, AST, lipid peroxide and nitric oxide levels in serum.
