COMPARISON OF THE CHEMICAL CHARACTERISTICS OF THE GENERA CREPIS L. AND PICRIS L. FROM THE FAMILY CICHORIOIDEAE USING HPLC TECHNOLOGY, WHICH IS WIDESPREAD IN EASTERN IRAQ
The results of the chemical analysis show the presence of eight phenolic compounds: Gallic acid, Rutin, Qurcetine, Kaempferol, Chlorogenic acid, Catechin, Vanillic acid, and Ferulic acid, with these compounds differing in their concentrations (or percentages) in the species of both studied sexes. The species are: Crepis foetida and Crepis sahendii. Crepis aspera, Picris babylonica (A), Picris babylonica (B), and Picris dasertorum. In any case, the phenolic compound Rutin recorded the highest concentrations of 30.25 micrograms/g in the species C.sahendii of the genus Crepis, compared to the concentrations of other phenolic compounds in the species of the genus Crepis, while the phenolic compound Vanillic acid showed the lowest concentration of 5.49 micrograms/g in the species C.foetida compared to the concentrations of the rest of the phenoles of the Crepis species. The phenolic compound Gallic acid recorded the highest concentrations of 33.08 micrograms/g in the P.babylonica (B) species of the genus Picris compared to the concentrations of other phenolic compounds of the same species of the genus Picris, while the phenolic compound Vanillic acid showed the lowest concentration of 9.00 micrograms/g in the species P.babylonica (A) compared to the concentrations of the rest of the phenols identified for types of the genus Picris
