T. Brande & G. W. Cox Dict. Sci., Lit. & Art (new ed.) I. 890/1 Filicic acid, an acid obtained from fern root. 1874 F. A. Flückiger & D. Hanbury Pharmacographia 669 The medicinal ethereal extract, of which the rhizome yields about 8 per cent., deposits a colourless, granular, crystalline substance, noticed by Peschier as early as 1826, and subsequently designated by Luck, Filicic Acid. 1892 Jrnl. Chem. Soc. 62 i. 380 The poisonous properties of fern extract are due to an amorphous substance which is the true filicic acid. The acid is readily converted into its lactone, by simply boiling its ethereal solution. The lactone is named filicin. 1958 Progress in Org. Chem. IV. 120 The ultra-violet absorption spectrum of filixic acid indicates a structure in which the three phenolic nuclei are separated by a methylene group. 1963 Acta Chem. Scand. XVII. 191 Naturally occurring filixic acid, the characteristic phloroglucinol derivative from Dryopteris filix mas, has been shown to be a mixture of six homologues, which differ from each other in regard to the acyl side chains of the filicinic acid nuclei. 1968 J. H. Burn Lect. Notes Pharmacol. (ed. 9) 123 Castor oil..aids the absorption of the filicic acid in the extract of male fern. < as lemmas |
