Phytochemical and antimicrobial screening of Linaria reflexa Desf

In continuation of our investigations on the genus Linaria (Scrophulariaceae) and especially on the spice Linaria reflexa Desf., we have present in this paper, the phytochemical screening, the structural determination of (+)-pinoresinol (1) and antirrhide (2) together with the antimicrobial activity face to bacterial and fungal strains: Escherichia coli, Bacillus sp., Yarrowia sp. and Candida sp. of the aerial parts of L. reflexa. Good presences were observed for alkaloids, flavonoids, leucoanthocyanins and Tannins. No effects were observed about the antibacterial activity, while the PE, AcOEt and n-BuOH extracts exhibits antifungal activity against Candida sp. This is the first report describing (+)-pinoresinol in the Scrophulariaceae family and the antimicrobial activity of L. reflexa.
