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 Mutarotation is the change in the ''optical rotation'' because of the change in the equilibrium between two anomers, when the corresponding stereocenters interconvert. Cyclic sugars show mutarotation as α and β anomeric forms interconvert.

of glucose in 1895. He also identified
quebrachitol in 1887 from the bark of ''
Aspidosperma quebracho''.
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.
