Forms: 1800s– morin, 1800s– morine.

Origin: A borrowing from French. Etymons: French morin, morine.

Etymology: < French morin (M. E. Chevreul 1830, in Jrnl. de chim. méd. 6 158; also morine) < scientific Latin Morus , genus name (see moric adj.) + French -in , -ine -in suffix¹. Compare German Morin (1844).

Chemistry.

A flavonoid found in the wood of old fustic and related trees, used as a yellow dye and as an antioxidant; 3,5,7,2′,4′-pentahydroxyflavone, C₁₅H₁₀O₇.
