Phenolic and other constituents of fresh water fern Salvinia molesta

Cytotoxicity, antioxidant activity and phenolic content of eight fern species, from north of Iran

“…18 Phenolic compounds are common metabolites in plants which have biological activities such as anti-inflammatory, anti-cancer and antioxidant. 19 Several extracts from ferns exhibited remarkable antioxidant capacity, comparable with vitamin C. 8 Flavonoids and other phenolic compounds have been demonstrated to be potent antioxidants. Hence, one of the functional properties of ferns that are pertinent to human health is their antioxidant activities.…”

Protective efficacy of natansnin, a dibenzoyl glycoside from Salvinia natans against CCl4 induced oxidative stress and cellular degeneration in rat liver

“…Salvinia natans was found to have a great potentiality for the removal of heavy metals like lead (Pb), cadmium (Cd), nickel (Ni), copper (Cu), chromium (Cr) and mercury (Hg) from waste water. The understanding of chemistry of Salvinia plants can help controlling their invasive growth, and promote their utilization for useful purposes [3]. The phytochemical investigation on S. natans showed that it consists of 96% of amino compounds [4].…”

Grevillosides J–Q, Arbutin Derivatives from the Leaves of <i>Grevillea robusta</i> and Their Melanogenesis Inhibitory Activity

“…The MeOH extract was then partitioned with solvents of increasing polarity. The 1-BuOH-soluble fraction was separated by means of various chromatographic procedures comprising column chromatography (CC) procedures including a highly-porous synthetic resin CC (Diaion HP-20), normal silica gel CC, reversed-phase (octadecyl silica (ODS)) CC, droplet counter-current chromatography (DCCC), and HPLC to afford eight new compounds, named grevillosides J-Q (1-8), together with ten known compounds (9)(10)(11)(12)(13)(14)(15)(16)(17)(18). The isolation details and yields are given in Experimental.…”

“…The isolation details and yields are given in Experimental. The structures of the new compounds were elucidated mainly by spectroscopic evidence, and those of known phenolic compounds were identified as graviquinone (9), 5) robustasides D (10) 3) and G (11), 6) p-hydroxybenzoic acid glucoside (12), 7) icariside D 2 (13), 8) 4-O-β-D-glucopyranoside-3-hydroxy methyl benzoate (14), 9) rutin (15), 10) and rhamnocitrin (16),absorption bands ascribable to hydroxy groups (3381 cm ). In the 1 H-NMR spectrum, two deshielded protons for an AA′BB′ spin-spin coupling system [δ H 6.94 (2H, d, J=9 Hz) and 6.68 (2H, d, J=9 Hz) were observed.…”

“…4) Further phytochemical work resulted in the isolation of eight new compounds, named grevillosides (J-Q) (1)(2)(3)(4)(5)(6)(7)(8) (Fig. 1), and ten known compounds (9)(10)(11)(12)(13)(14)(15)(16)(17)(18) (Fig. 2).…”
