 Angelic acid was first isolated by the German pharmacist Ludwig Andreas Buchner (1813–1897) in 1842 from the roots of the garden plant angelica ("Angelica archangelica") that gave the acid its name.Angelic acid occurs in the roots of many plants, especially of the family Apiaceae.These plants include "Angelica archangelica", "Peucedanum ostruthium" (masterwort), "Levisticum officinale" (lovage), "Euryangium sumbul" and "Laserpitium latifolium".
