Abstract
Artemisia arborescens is a medicinal and aromatic plant used in traditionally by the people of Saudi Arabia. This research attempts to evaluate the bioactive constituents of the plant using organic solvents, as well as the antibacterial and anticancer properties of plant extracts. The Phytochemical analysis of methanol extract revealed eleven bioactive constituents, identified by comparing their retention periods and GC-MS profiles to account for 52.45 percent of the studied extract. In the meantime, the extract of pet ether had demonstrated the presence of sixteen significant constituents, six of which were distinct sesquiterpene derivatives. In lipophilic plant extract, three higher alkanes made up 12.49% of the total. These higher alkanes were tetratriacontane (6.55%), hentriacontane (4.17%), and octacosane (1.77%). Studies on antimicrobial activity have revealed that both methanolic and petroleum ether extracts had a broad spectrum of activity against specific human pathogens. Both extracts, however, failed to exhibit any anti-Candida albicans activity. Methanolic extract not shown inhibition in the cell growth of MCF-7 cell, but petroleum ether extract had shown significant anti-cancer activity against MCF-7 cell with an IC50 of 13.49 mu g/mL. the results obtained show that A. arborescens have a lot of potential for further research into variety of biological functions, against cancer and microbes.
