History
Ellagic acid was first discovered by chemist Michel Eugène Chevreul in oak galls and was more closely examined by Henri Braconnot in 1831. Buchner was the first to show in 1845 that ellagic acid is formed when alkaline solutions of gallotannin are exposed to air. Maximilian Nierenstein prepared this substance from algarobilla and certain other fruits in 1905. He also suggested its formation from galloyl-glycine by Penicillium in 1915. Löwe was the first person to synthesize ellagic acid by heating gallic acid with arsenic acid.

Famous quotes containing the word history:
“The only thing worse than a liar is a liar that’s also a hypocrite!
There are only two great currents in the history of mankind: the baseness which makes conservatives and the envy which makes revolutionaries.”

“Psychology keeps trying to vindicate human nature. History keeps undermining the effort.”
—Mason Cooley (b. 1927)
“Yet poetry, though the last and finest result, is a natural fruit. As naturally as the oak bears an acorn, and the vine a gourd, man bears a poem, either spoken or done. It is the chief and most memorable success, for history is but a prose narrative of poetic deeds.”
—Henry David Thoreau (1817–1862)
