The genetic similarities of four species of Glycyrrhiza plants were determined by DNA analyses of random amplified polymorphic DNA (RAPD) and restriction fragment length polymorphism (RFLP). The phylogenic trees were constructed from the genetic similarities estimated from RAPD and RFLP profiles. These results indicated that G. glabra and G. uralensis, rich in glycyrrhizin, are more closely related to each other than to G. echinata or to G. pallidiflora.
