Antimicrobial activity of some Ganoderma species from Nigeria
TLDR
Preliminary thin layer chromatography chemical tests on extracts of Ganoderma showed that they contained compounds that stained blue–violet and blue or green when sprayed with anisaldehyde–sulphuric acid or Dragendorff, respectively, and the profile of compounds showed some variation among the four species.
Inhibitory activities of lichen-derived compounds against methicillin- and multidrug-resistant Staphylococcus aureus.
TLDR
The inhibitory effects of selected phenolic lichen substances were tested against a panel of methicillin- and multidrug-resistant Staphylococcus aureus, and hybocarpone was by far the most active.
Iridoid and phenylethanoid glucosides from Veronica lavaudiana.
TLDR
From an extract of Veronica (sect. Hebe) lavaudiana, mannitol and isolated 11 iridoid glucosides, the carbohydrate ester hebitol II, and four phenylethanoid glycoside esters are identified, demonstrating that the structures of the known glycosides globularitol and hebitols I and II should be revised.
Quantifying the metabolic cost to an Antarctic liverwort of responding to an abrupt increase in UVB radiation exposure
TLDR
Analysis of metabolic cost to the Antarctic leafy liverwort Cephaloziella varians of responding to an abrupt increase in ultraviolet B (UVB) radiation exposure in the natural environment at Rothera Point indicated that nonphotochemical quenching was higher in the thalli formerly under the screens than in those not previously covered with screens.
