Rapid Identification of Digitalis purpurea Using Near‐Infrared Reflectance Spectroscopy

Glycosides from Digitalis are widely used for the treatment of various cardiac conditions. The potential for near‐infrared (NIR) spectroscopy as a technique for the rapid identification of Digitalis purpurea was studied. If successful, this method would be advantageous over traditional methods which are destructive and time‐consuming.
