Charles Joseph Tanret

Charles Joseph Tanret (9 August 1847 in Joinville, France – 10 July 1917 in Paris) was a French pharmacist and chemist.

He notably studied the chemistry of sugars, reporting his observations of the mutarotation of glucose in 1895.[1] He also identified quebrachitol in 1887 from the bark of Aspidosperma quebracho.[2]

His son Georges was also a pharmacist, specialist of plant chemistry. Georges Tanret identified an alkaloid (galegine) from Galega officinalis that was evaluated in clinical trials in patients with diabetes in the 1920s and 1930s.[3][4]
