Regulatory Status. Trifolium species are GRAS as natural flavorings and seasonings ( 182.10). Essential oils, solvent-free oleor-esins and natural extractives of Trifolium species are also GRAS ( 182.20).

The QAs occurred in all the legume genera, species and sub-species studied. There were both QAs and QAs plants (Table 28). The frequency of QA occurrence mostly varied (0.1-0.8) between species (P< 0.001). The smallest frequency was found in only two species. Trifolium arvense and Trifolium pratense, in which positive test results were not found more frequently than every tenth individual (Table 28). 

The latter-mentioned Medicago sub-species exhibited a positive correlation (r = 0.49) with M. lupulina (Figure 110). Differences were also found within the genus Trifolium and the genus Vida, and the evolutionary tendencies of both species were shown to be similar (Figures 111-112). The analyses of the correlations and the best strongly confirmed the utilization of MFCs as a method of evolutionary analysis.
