α.

1817 T. Thomson Syst. Chem. (ed. 5) IV. 48 Ulmin..was first noticed in 1804, by Klaproth, who found it in a spontaneous exudation from the elm.

1819 W. T. Brande Man. Chem. 366 Ulmin is of a dark brown colour, with scarcely any taste or smell... The exudation from the elm is generally combined with carbonate of potassa, and is therefore readily soluble in water.

1842 Penny Cycl. XXII. 26/1 Simaruba is the bark of the root of the Simaruba amara... Its chief constituents are..ulmin, mucilage, and some salts.

β. 1838 M. F. Tupper Proverb. Philos. Notes 219 With reference to the elm, I would remark, that no use has yet been discovered in the principle called ‘ulmine’.1853 J. F. Royle Man. Materia Med. (ed. 2) 632 It [the bark of Elm] contains Tannin..and a peculiar mucilaginous or gummy principle, called Ulmine.

2. A dark-brown or black product resulting from the decay of wood or vegetable matter, or artificially obtained by the action of powerful chemical agents on sugar and some other substances.
