Tyrosinase Inhibitory Prenylated Flavonoids from Sophora flavescens

Biological and Pharmaceutical Bulletin, 2003
For the purpose of the development of a skin-whitening agent, Sophora flavescens was evaluated for tyrosinase inhibitory activity and its active principles were identified following activity-guided isolation. The ethanol extract and dichloromethane fraction from S. flavescens showed significant inhibition of mushroom tyrosinase.

Elevated quinolizidine alkaloid content in grains of sweet narrow‐leaved lupins when intercropped with oats

Journal of the Science of Food and Agriculture, Volume 106, Issue 5, Page 2917-2927, 30 March 2026.
Abstract BACKGROUND Narrow‐leaved lupins (NLL, Lupinus angustifolius L.) is recognized as a climate‐resilient protein crop but its use in food and feed is frequently limited by toxic quinolizidine alkaloids (QAs). The effect of intercropping with spring oat (Avena sativa L.) on grain QA content has not yet been quantified.
