eugeninn.

Brit.

/ˈjuːdʒᵻnɪn/, U.S.

/ˈjudʒənən/

Forms: 1800s– eugenin, 1800s–1900s eugenine.

Origin: Formed within English, by derivation; partly modelled on a French lexical item. Etymons: Eugenia n., -in suffix¹.

Etymology: < Eugenia n. + -in suffix¹. In sense 1 after French eugénine (J. F. Bonastre 1834, in Jrnl. de Pharmacie 20 566), German Eugenin (1835 in Annalen der Pharmacie 13 92, in a translation of the same article).With sense 2 compare German Eugenin (1948 in this sense). With the form eugenine compare -ine suffix⁵.

Chemistry.

†1. A white solid substance obtained from an aqueous distillate of oil of cloves (probably a hydrate or other derivative of eugenol). Obsolete.

ΚΠ

1835 Amer Jrnl. Pharmacy 7 83 M. Bonastre has discovered a new crystalline substance in cloves, and which he calls Eugenine.

1837 London & Edinb. Philos. Mag. 11 338 Bonastre obtained from the distilled water of aromatic pink, a crystalline substance..; it has been named by him eugenin.

1838 Penny Cycl. X. 66/1 The taste of eugenin is but slight, and the smell much less strong than that of the clove.

1902 H. Kraemer Course Bot. & Pharmacognosy ii. 180 Cloves also contain..eugenin (isomeric with eugenol or eugenic acid) which resembles caryophyllin but becomes reddish with nitric acid.

2. A bitter-tasting chromone originally isolated from the buds of wild clove trees.Eugenin is 5-hydroxy-7-methoxy-2-methylchromone.

1980 T. J. Simpson in Biosynthesis (Royal Soc Chem.) 6 i. 14 Fungal infection..induces formation of the phytoalexins (stress compounds) 6-methoxymellein and eugenin in carrot roots.

1989 R. Ibrahim & D. Barron in J. B. Harborne Methods in Plant Biochem. I. iii. 78 Most simple substituted chromones, such as eugenin,..occur in rhizomes, heartwood and stem bark of several species.
