quinovinn.

Brit.

/ˈkwɪnəvɪn/, U.S.

/ˈkwɪn(ə)vɪn/

Forms: 1800s– chinovin, 1800s– kinovin, 1800s– quinovin.

Origin: Formed within English, by derivation; modelled on a German lexical item. Etymons: quinovic adj., -in suffix¹.

Etymology: < quinov- (in quinovic adj.) + -in suffix¹, after German Chinovin ( C. Löwig Grundriss der organischen Chemie (1852) 426).

Chemistry. Now rare.

A mixture of glycosides of quinovic and cinchonic acids occurring in cinchona (and originally false cinchona) bark.False cinchona is perhaps cascarilla, genus Ladenbergia.

1909 Cent. Dict. Suppl. Kinovin, an organic substance of neutral character, found in cinchona-bark, which on boiling with dilute acid yields kinovic acid and a sugar-like substance called kinovite.
