These compounds are of interest, not only because of their opine nature, but also because they interact with the biological control agent of crown gall, Agrocin 84, altering its toxicity. In the present investigation Agrocinopine C has been isolated, and purified by a combination of anion and cation exchange chromatography and H.V.P.E. Degradative and physico­chemical studies have shown that Agrocinopine C consists of D-glucose-2-phosphate, linked in a phosphodiester bond to the sixth carbon of the glucose moiety of a sucrose molecule. Agrocinopine D is closely related, the only difference being the loss of the fructose moiety of the sucrose molecule.Agrocinopine CTheses
