In 1806, working with asparagus, he and Pierre Jean Robiquet (future discoverer of the famous red dye alizarin, then a young chemist and his assistant) isolated the amino acid asparagine, the first one to be discovered. He also discovered pectin and malic acid in apples, and isolated camphoric acid and quinic acid.
His death occurred while he was on a visit to his birthplace.
Among his best known works is "Manuel de l'essayeur" (Manual of the assayer).
The plant genus Vauquelinia is named in his honor, as is the Vauquelin, an egg white foam associated with molecular gastronomy, and the mineral vauquelinite, discovered at the same mine as the crocoite from which Vauquelin isolated chromium.
