for licorice, but determined that the active principles were not closely allied 

 to glycyrrhizin. Dieterich reports that the glucosides are present in very 

 small quantities, that their isolation is rather expensive and attended by 

 consi(lcral)Ie diflicuUy, and that the crude preparation comparable to licorice 

 extract is with difficulty soluble and has a very bitter aftertaste. He states 

 also that the plant is a very small one which occurs only in (lie mountainous 

 regions of I'araguay. For these reasons he is very skeptical as to its potential 

 commercial value, although both he and Rasenack suggest the advisability of 

 cultivation experiments outside of South America." {E. E. Stanford.)
