Alkaloid profile of Italian alpine milk.

ABSTRACT: This study examines the alkaloid profiles in alpine milk. Alkaloids could pose a health concern but also prove interesting from a geographic traceability perspective. Over three consecutive days, 48 daily milk samples were collected from 16 lactating cows grazing on two alpine pastures in Northeast Italy, with 8 cows from each pasture. Simultaneously, alpine herbs selecting by the cows during grazing were collected using the hand-plucking technique. Additionally, 12 milk mass samples were obtained from an entire herd of 110 cows. Liquid chromatography coupled with high-resolution mass spectrometry was employed to analyze both herbage and milk samples, identifying 41 alkaloids with pure standards and putatively identifying another 116. The results revealed a transfer of 0.4% for pyrrolizidi
