Watumiaji waliosajiliwa tu ndio wanaweza kutafsiri nakala

Ingia / Ingia

Two isocoumarin derivatives, one new, erythricin (1) and a known erythrocentaurin (2) were isolated from the whole plant of Centaurium pulchellum Druce. The 13C-NMR data of compound 2 are described. The structures of compounds 1, 2 were elucidated on the basis of spectral analysis including 2D-NMR

Ingia / Ingia

The main principles of C. pulchellum (Sw.) Druce, secoiridoid glycosides, have been studied as potent bioactive compounds. Here we scored their content in extracts of ten populations of this species. Antibacterial and antifungal assays of the extracts and pure secoiridoid glycosides were performed

Ingia / Ingia

Based on ethnopharmacological and taxonomic information, seeds of 21 Scottish plant species from 14 different families were obtained from authentic seed suppliers. Their n-hexane, dichloromethane and methanol extracts were assessed for antibacterial activity against 11 pathogenic bacterial species.

Ingia / Ingia

Methanol extracts of aerial parts and roots of five centaury species (Centaurium erythraea, C. tenuiflorum, C. littorale ssp. uliginosum, C. pulchellum, and Schenkia spicata) were analysed for their main secondary metabolites: secoiridoid glycosides, a group of monoterpenoid compounds, and phenolics

Ingia / Ingia

Gentiopicroside (1), a secoiridoid glycoside isolated from the methanol extract of the aerial parts of Centaurium erythraea, has been assessed for antibacterial and free radical scavenging activities. General toxicity of 1 has also been determined by brine shrimp lethality bioassay.

Volatile organic compounds from Centaurium erythraea Rafn (Croatia) and the antimicrobial potential of its essential oil.
