The isolation of previously undescribed 12 compounds from the MeOH extract of Jacobaea vulgaris whole plants is disclosed, comprising 11 dihydrostilbenes (1-11) and one flavanone (12), and eight known compounds (six flavonoids, one dihydrostilbene, and one caffeoylquinic acid). Structural elucidation employed spectroscopic methods, including 1D and 2D NMR spectroscopy, HRESIMS, and ECD calculations. Evaluation of the compounds' effects on PCSK9 and LDLR mRNA expression revealed that compounds 1 and 3 downregulated PCSK9 mRNA while increasing LDLR mRNA expression, suggesting potential cholesterol-lowering properties.

Toxic Plants and Their Impact on Livestock Health and Economic Losses: A Comprehensive Review.

Plants are important components in sustaining the life of humans and animals, balancing ecosystems, providing animal feed and edible food for human consumption, and serving as sources of traditional and modern medicine. However, plants can be harmful to both animals and humans when ingested, leading to poisoning regardless of the quantity consumed. This presents significant risks to livestock health and can impede economic growth.

Tansy ragwort ( L.) growing in animal pasture may pose a risk to humans due to the potential transfer of pyrrolizidine alkaloids (PAs) into food of animal origin. Here, we investigated what amount of PAs corresponds to the amount of ragwort consumed by sheep on a pasture and whether the ingested PAs are transferred into edible tissue.

Article Synopsis
- The study details the first confirmed case of pyrrolizidine alkaloid poisoning in a horse, specifically a six-year-old Irish cob mare that exhibited severe liver damage leading to euthanasia.
- Despite intensive treatment, the mare's condition worsened, with post-mortem examinations revealing significant liver damage and the presence of pyrrolizidine alkaloid metabolites in her tissues.
- The findings suggest that typical histopathological signs of pyrrolizidine alkaloid poisoning may not always be present, highlighting the complexity of diagnosing this type of poisoning in equine patients.
Plastid phylogenomics of Robinsonia (Senecioneae; Asteraceae), endemic to the Juan Fernández Islands: insights into structural organization and molecular evolution.

Background: The genus Robinsonia DC. (tribe Senecioneae, Asteraceae) endemic to the Juan Fernández Islands in Chile is one of the most conspicuous insular plant groups in the world. Unlike typical herbaceous Asteraceae plants, these plants demonstrate spectacular and unusual rosette tree growth forms as shown by the alpine giant senecios (genus Dendrosenecio, tribe Senecioneae) endemic to the East African mountains.

Article Synopsis
- The Asteraceae family, known for its vast diversity, faces challenges in classification due to complex morphological traits and a need for better understanding of chloroplast genomes to enhance taxonomic accuracy.
- This study sequenced and analyzed the chloroplast genomes of 14 Asteraceae species, revealing a typical quadripartite structure and a high level of conservation across their gene content and arrangement, while also identifying certain genes as evolutionary hotspots.
- The phylogenetic analysis suggested new classifications for some species, indicating potential shifts in understanding their evolutionary relationships, which is important for future research in molecular identification and population genetics.
