Forms: 1800s purpureïn, 1800s– purpureine, 1900s– purpurein.

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

Etymology: < classical Latin purpureus (see purpureous adj.) + -in suffix¹, after orcein n. N.E.D. (1909) enters this under purpureïn and gives the pronunciation as (pɒɹpiū^ə·riˌin) /pɜːˈpjʊəriːɪn/.

Chemistry.

†1. A brown crystalline compound produced by the reaction of purpurin with ammonia. Obsolete.Systematic name: 1,3-dihydroxy-4-aminoanthraquinone; C₁₄H₉NO₄.

1864 J. Stenhouse in Proc. Royal Soc. 13 149 This compound being in its mode of formation and physical properties very analogous to orceine, I have called it purpureine.

1866–8 H. Watts Dict. Chem. IV. 749 Purpureïn or purpuramide is nearly insoluble in sulphide of carbon.

2. A glucoside extracted from the purple willow, Salix purpurea.

1970 Phytochemistry 9 853 A new glucoside, purpurein, was isolated from fresh June bark of Salix purpurea.

2005 Analytica Chimica Acta 545 55/2 The second group [of phenolic glycosides present in Salix] comprises the phenolic glucosides: picein, purpurein, syringin, etc.

3. An alkaloid extracted from the tropical American tree Annona purpurea (family Lauraceae) and various other plants, esp. of the genus Thalictrum (family Ranunculaceae).
