Gmelinoside I (1), a new flavonol glycoside, was isolated and chemically characterized as 3,5,7,3′,4′,5′-hexahydroxy-3-O-α-D-galactopyranosylflavone from the aerial part of Limonium gmelinii (Plumbaginaceae) by UV, IR, ID and 2D NMR and HRESIMS experiments. Five compounds (2–6) were also isolated and identified as, (-)-epigallocatechin-3-O-gallate (2), myricetin (3), myricetin-3-O-α-L-rhamnopyranoside (4), myricetin-3-O-β-D-galactoside-6((Prime))-O-gallate (5) and caprolactam (6). The antibacterial, antifungal and antileishmanial activities [1] of the isolated compounds were evaluated. Fig.1 Acknowledgments: Z.A.K is thankful for Kazakhstan government for financial support.
