Amygdalin

Amygdalin (from Greek: ἀμυγδαλή amygdálē "almond"), C₂₀H₂₇NO₁₁, is a glycoside initially isolated from the seeds of the tree Prunus dulcis, also known as bitter almonds, by Pierre-Jean Robiquet and Antoine Boutron-Charlard, in 1830 and subsequently investigated by Liebig and Wöhler in 1830. Several other related species in the genus of Prunus, including apricot (Prunus armeniaca) and black cherry (Prunus serotina), also contain amygdalin.
