Flavonolignan

Part of speech: noun

Definitions

1. A compound type formed by the combination of flavonoids and lignans, known for antioxidant properties and found in certain plants and foods
2. A chemical substance resulting from the fusion of flavonoid and lignan structures, typically exhibiting health-related bioactivities and occurring naturally in some botanical sources
3. A molecule composed of linked flavonoid and lignan units, recognized for its role in plant biochemistry and potential benefits in nutrition and medicine

Etymology: Flavonolignans are a family of plant compounds named by blending two older chemical class names: flavonoids, the yellow-to-colourless pigments and antioxidants found in fruits, vegetables and tea, and lignans, the phenolic compounds that make up part of plant cell walls. The name is a portmanteau, so its meaning is simply the sum of its parts: a molecule that carries both a flavonoid skeleton and a lignan-type unit. The best-known example is silymarin, a mixture extracted from milk thistle (Silybum marianum), which is why that plant is so often associated with these compounds. Silymarin is itself a group of related flavonolignans rather than a single substance, and its name follows the same pattern of joining a plant-derived root to a chemical suffix.
