#### 2.2.1. Pytochemical Screening  
Results of the phytochemical screening carried out on the hydroalcoholic extracts of the different parts of _A.P_ var. _pyrehtrum_ and _A.P_ var. _depressus_ are shown in Table 5.

The results of the phytochemicalal screening tests of the different parts of _A.P_ var. _pyrethrum_ and _A.P_ var. _depressus_ shown in Table 5 indicate the presence of several chemical compounds. Tannins are present in all parts except in the empty capitula and leaves of _A.P_ var. _pyrethrum_ (CPP, FPP) and in the seeds of both varieties (GPP, GPD). Flavonoids are present in all extracts, with a high concentration in the roots of _A.P_ var. _depressus_ (RPD). Sterols and terpenes are detected in the two varieties, with higher concentrations in roots and seeds than in empty capitula, while they are absent in leaves. Alkaloids are present in all parts of the two varieties, but in small amounts in the roots and seeds compared to the leaves and empty capitula. The moss indices show that the content of saponins is high in the empty capitula of the variety _A.P_ var. _depressus_ (CPD), while they are clearly absent in the leaves of the two varieties (FPP and FPD) and the roots of the variety _A.P_ var. _pyrethrum_ (RPP). Free quinone is present in _A.P_ var. _pyrethrum_ (GPP) seeds, while it is absent in _A.P_ var. _depressus_ (GPD) seeds. Cardiac glycosides, oses, and holosides are absent in the seeds and roots of the two varieties. Finally, it should be noted that mucilage is absent in all the extracts studied. The phytochemical characterisation of the two studied varieties is essential to identifying bioactive molecules. Some of these results are consistent with previous work by [50; 63; 81; 82; 83], which showed the presence of flavonoids, alkaloids, and tannins, as well as the presence of mucilage in methanolic extracts of _Anacyclus pyrethrum_ (L.). However, hydroethanolic extracts reveal the absence of mucilage. Our phytochemicalal tests carried out for the first time on the different parts of the two varieties, _A.P_ var. _depressus_ and _A.P_ var. _pyrethrum_, demonstrated the presence of alkaloids, tannins, sterols, and triterpenes, as well as oses and holosides, in the seeds, leaves, empty capitula, and roots of the two varieties. Through phytochemical screening, we were able to identify and characterise the chemical composition of different parts of the two studied varieties.
