Sparteine-type alkaloids with anti-tomato spotted wilt virus from the seeds of Lupinus angustifolius L.

Key Points

• Sparteine-type alkaloids exhibit anti-tomato spotted wilt virus activity against the pathogen.
• In vitro assessments show a significant reduction in viral activity, with notable efficacy observed at high concentrations.
• Laboratory analysis of Lupinus angustifolius seeds identifies these alkaloids as a promising biological agent against the virus.
• Application of these findings could enhance agricultural practices, potentially reducing reliance on chemical treatments.
