Abstract This study examines the alkaloid profiles in alpine milk. Alkaloids could pose a health concern but also prove interesting from geographic traceability perspective. Over three consecutive days, 48 daily milk samples were collected 16 lactating cows grazing on two pastures Northeast Italy, with 8 each pasture. Simultaneously, herbs selecting by during using hand‐plucking technique. Additionally, 12 mass obtained an entire herd of 110 cows. Liquid chromatography coupled high‐resolution spectrometry was employed to analyze both herbage and samples, identifying 41 alkaloids pure standards putatively another 116. The results revealed transfer 0.4% for pyrrolizidine alkaloids, 2.7% indole 12% steroidal A partial least squares—discriminant analysis model based achieved correct reclassification 67% distinct pastures. Despite minimal transfer, which should be considered positive terms health, it opens door studies use as markers mountain products. Practical Application provides novel perspective interaction between systems composition. research useful enhancing pasture products healthiness can help prevent fraud declaration origin.

Phytochemical Profiling Studies of Alkaloids and Coumarins from the Australian Plant Geijera parviflora Lindl. (Rutaceae) and Their Anthelmintic and Antimicrobial Assessment

Metabolites, Journal Year: 2024, Volume and Issue: 14(5), P. 259 - 259

Published: April 30, 2024

Phytochemical profiling followed by antimicrobial and anthelmintic activity evaluation of the Australian plant Geijera parviflora, known for its customary use in Indigenous ceremonies bush medicine, was performed. In present study, seven previously reported compounds were isolated including auraptene, 6′-dehydromarmin, geiparvarin, marmin acetonide, flindersine, two flindersine derivatives from bark leaves, together with a new compound, chlorogeiparvarin, formed as an artefact during isolation procedure mixture geiparvarin. Chemical allowed qualitative quantitative comparison bark, flowers, fruit this plant. Subsequently, subset these well crude extracts evaluated their activities. Anthelmintic assays showed that compounds, auraptene dichloromethane methanol G. displayed significant against parasitic nematode (Haemonchus contortus). This is first report associated indicates importance such fundamental explorations discovery bioactive phytochemicals therapeutic application(s).
