rubidinen.

Brit.

/ˈruːbᵻdiːn/, U.S.

/ˈrubəˌdin/,

/ˈrubədn/

Forms: 1800s– rubidin, 1800s– rubidine.

Origin: A borrowing from Latin, combined with an English element. Etymons: Latin rubidus , -ine suffix¹.

Etymology: < classical Latin rubidus red (see rubid adj.) + -ine suffix¹. In sense 1 after German Rubidin (G. Thenius 1862, in Chem. Central-Blatt 7 56); the compound is so called because its salts tend to turn red. In sense 2 after French rubidine (A. De Negri & J. De Negri 1880, in Mondes 51 67). N.E.D. (1910) gives the pronunciation as (rū·bidəin) /ˈruːbɪdaɪn/.

Chemistry. Now rare.

1. A compound obtained by distilling coal tar, perhaps a homologue of pyridine.Its formula was given as C₁₁H₁₇N.

2. A red carotenoid pigment isolated from the watermelon, Citrullus lanatus (formerly called Cucumis anguria).

1922 L. S. Palmer Carotinoids ii. 83 A. and G. de Negri (1879) regarded the tomato pigment as identical with the rubidin which they isolated from the watermelon.
