Abstract
Farsetia aegyptia Turra (Family Brassicaceae) is a perennial woody desert shrub native to Saharan Arabia. The current studyaims to define the chemical composition of the F. aegyptia, collected from Rawdat-Khuraim, Riyadh Region, Saudi Arabia, and evaluate the extract's allelopathic, and antioxidant properties. Fourteen components from the extracted plant were identified using the GC/MS method, making up all of the volatile chemicals in the plant. Whereas, (-)-spathulenol (26.71%) is considered to be the main constituent, but other constituents with higher percentages of composition were also categorised, including carvacrol (12.34%), pivalate limonen-6-ol (6.83%), glafenin (7.67%), 13,16-octadecadienoic acid, methyl ester (9.79%), and β-sitosterol (8.99%). The shoot extract is the most potent of the components of F. aegyptia that were isolated, with an IC50 value of 37.26 mg.L-1 and percentage of radical scavenging activity (RSA) of 67.60%. The methanolic extract showed a substantial allelopathic inhibitory action against the germination, seedling root, and shoot development of C. murale with IC50 values of 0.921, 0.747, and 0.551 mg.mL-1.. It is suggested that additional study be done on the mechanisms and mode(s) of action of these compounds as antioxidants or allelochemicals, as well as on the main compound action of authentic, pure materials, either alone or in combination
