The primary objective of this thesis was to conduct a comprehensive bibliographic research on Elaeagnus angustifolia L., a spiny and deciduous tree also referred to as oleaster, Russian olive, Persian olive or silver tree. The research is focused on the chemical studies, as well as the pharmacological activity of this plant. In order to make this thesis a valuable scientific work, during the research, it has been tried to use reliable sources and articles available in the literature.

Elaeagnus angustifolia L. belongs to the Elaeagnaceae family and grows in arid and semi-arid regions. It is estimated that there are more than 90 species of Elaeagnus found throughout the world, with the majority of them being found in subtropical regions in Asia, Europe and some parts of North America. Elaeagnus angustifolia L. looks like an olive tree and produces small and reddish-brown oval-shaped, sweet, and edible fruits.

Oleaster tree roots, leaves, flowers, fruits, fruits peel, and seeds are used in food, folk medicine, medicine, pharmacy, cosmetics, and perfumery. There are many nutritional benefits to the fruits of the oleaster, including protein, sugar, vitamins, and minerals, and they are a natural source of phenolics, flavonoids, and terpenoids, as well as alternative functional ingredients in the food industry. Throughout history, Elaeagnus angustifolia L. was used as an astringent, kidney stone removal, anti-inflammatory, and pain reliever. It was also used as a remedy for fever, jaundice, asthma, tetanus, and rheumatoid arthritis.

Elaeagnus angustifolia L. has been extensively researched for its biological and pharmacological properties. Its main biological and pharmacological properties include antimicrobial, antioxidant, cardioprotective, anti-arthritic, wound healing, antinociceptive, anti-inflammatory, hypolipidemic, antimutagenic, antitumor, as well as gastroprotective effects. Considering the wide range of pharmacological properties, as well as the wide range of phytochemical agents present in Elaeagnus angustifolia L., it is a good candidate for the discovery of new drugs.
