Names and Discovery
In 1819 Pelletier and Caventou isolated a peculiar volatile and crystallizable acid from the seeds of Schoenocaulon officinalis, a Mexican plant of family Melanthaceae (also called cevadilla or sabadilla). Consequently the substance was named sabadillic or cevadic acid. It was later found to be identical with Frankland and Duppa's methylcrotonic acid (1865). In 1870 Geuther and Fröhlich prepared an acid from croton oil to which they gave the name tiglic acid (or tiglinic acid) after (Croton) tiglium (Linn.), specific name of the croton oil plant. The compound was shown to be identical with the previously described methyl-crotonic acid.

Famous quotes containing the words names and/or discovery:
“In a time of confusion and rapid change like the present, when terms are continually turning inside out and the names of things hardly keep their meaning from day to day, it’s not possible to write two honest paragraphs without stopping to take crossbearings on every one of the abstractions that were so well ranged in ornate marble niches in the minds of our fathers.”
—John Dos Passos (1896–1970)
“The discovery of the North Pole is one of those realities which could not be avoided. It is the wages which human perseverance pays itself when it thinks that something is taking too long. The world needed a discoverer of the North Pole, and in all areas of social activity, merit was less important here than opportunity.”
—Karl Kraus (1874–1936)
