Brit.

/ˈpəːpjᵿrɪn/, U.S.

/ˈpərp(j)ər(ə)n/

Forms: 1500s 1700s– purpurine, 1800s– purpurin.

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

Etymology: < classical Latin purpura purple (see purpure n.) + -in suffix¹. In sense 1 after Middle French, French purpurine (1557 in this sense, in the passage translated in quot. 1558, subsequently from 1731), itself apparently after Italian porporina (late 14th or early 15th cent.); compare Spanish purpurina (1569 in this sense). In sense 2 probably after French purpurine (1827 in this sense: P. J. Robiquet & J. J. Colin, in Ann. de chimie et de physique 34 244).

†1. Powdered brass or bronze mixed with liquid and used as a colouring material. Obsolete.

1839 A. Ure Dict. Arts 785 Purpurine, the crude substance from which they profess to extract alizarine, is a richer dye than this pure substance itself.

1853 T. F. Betton tr. H. V. Regnault Elements Chem. 706 The residue [is] treated several times with ether, when a colouring matter dissolves, called purpurin or madder-purple.

1938 R. Hum Chem. for Engin. Students xviii. 481 The two dyes, alizarine and purpurin, are present in it [sc. madder], and these have been synthesised, the artificial product having displaced the natural one.

†3. Medicine. Any of various substances giving a purple or pink colour to urine or urinary sediments; esp. uroerythrin. Obsolete.

ΚΠ

1845 Brit. & Foreign Med. Rev. 20 64 This substance is usually found in combination with urate of ammonia, which has so strong an affinity for it, as always to become deeply coloured by purpurine.

1858 R. G. Mayne Expos. Lexicon Med. Sci. (1860) 1046/2 Purpurin,..name given to a substance whose presence in the urine is indicative of serious functional or organic mischief in some of the organs connected with the portal circulation.

1877 Lancet 13 Jan. 74/1 The urine turned to a reddish violet on the addition of nitric acid and heat, which I suppose was due to the presence of purpurine.
