Two new coumarins () have been isolated from a methanol extract of branches. The structures of compounds and have been elucidated as 6-isopentenyl -7-benzoyl-coumarin and 3-isopentenyl-7-benzoyl-coumarin based on extensive spectroscopic analysis, including IR, NMR, and MS. The inhibitory activity of compounds and against HeLa and HepG2 cell lines has been described.

Ambrosia trifida is an invasive weed that destroys the local ecological environment, and causes a reduction in population diversity and grassland decline. The evolution of herbicide resistance has also increased the difficulty of managing A. trifida, so interspecific plant competition based on allelopathy has been used as an effective and sustainable ecological alternative.

An antiviral effect of extracts prepared from aerial parts of nine species and from leaves of two species of the genus L. was investigated for potential antiviral activity toward influenza A (H1N1) virus. The toxicity of dry extracts was analyzed, and the most selective extract was identified in vitro.

An intrinsic metal cluster NIR-II emission of the {TaBr} aqua/hydroxocomplexes was determined in aqueous solutions under inert atmosphere. The photoluminescence (PL) is enhanced in DO, and the lifetime scale expands from nanoseconds to microseconds. Possible cluster emission transitions have been assigned and analyzed from a computational perspective.
