Chemical analysis and biological activity of the essential oils and extracts of two liverwort species growing in Turkey
(University Belgrade, 2023)
The aim of this study was to investigate the chemical composition of the essential oils (EOs) from two Diplophyllum species and to evaluate their bioactivity potential [antimicrobial, antioxidant, anti-urease, anti-xanthine ...
Use of Dicranum polysetum extract against Paenibacillus larvae causing American Foulbrood under in vivo and in vitro conditions
(Springer, 2023)
Recent research shows that Dicranum species can be used to ameliorate the negative effects of honeybee bacterial diseases and that novel compounds isolated from these species may have the potential to treat bacterial ...
Dihydroisocoumarins and phenylglycosides from scorzonera longiana, their antimicrobial activities and molecular docking studies
(Wiley, 2023)
Five new phenyl dihydroisocoumarin glycosides (1-5) and two known compounds (6-7) were identified from the butanol fraction of Scorzonera longiana. The structures of 1-7 were elucidated based on spectroscopic methods. ...
