A full account of the structure elucidation of an iridoid lactone, rehmaglutin C, and a chlorinated tricyclic iridoid glucoside, glutinoside, is presented. Rehmaglutin C (10) and glutinoside (11) were isolated from Chinese Rehmanniae Radix, the dried root of Rehmannia glutinosa LIBOSCH, from China, called Kan-jio in Japanese. The absolute stereostructures 10 and 11 have been determined on the basis of chemical and physicochemical evidence which included application of the exciton chirality method for the allylic benzoyl derivative.
