Tetraena qatarense is one of the most abundant plants in the Arabian Peninsula and a native plant in Qatar. It is a salt- tolerant dwarf shrub with multiple stems and fleshy leaves. The objective of this research is to carry out phytochemical screening of triterpenoids saponins and test their biological activity. Plant material was collected from Qatar university campus during winter and summer months. The plant materials were dried for 24 hours at 60 oC, the dry leaves were grinded into fine powder and extracted with 95% methanol for 24 hours using Soxhlet. Presence of triterpenoid saponins was confirmed by the formation of persistent foam and Liebermann-Buchard test. The isolated triterpenoid saponin was purified by solvent separation using butanol and it was further subjected to gas chromatography (GC/MS) analysis and high-performance liquid chromatography (HPLC). The pure and crude triterpenoid saponin extract will be tested for biological activity.
