The carob tree (Ceratonia siliqua L.) belongs to the legume family and is mainly cultivated in the Mediterranean. Ceratonia siliqua L. is a medicinal plant used in traditional Algerian medicine. Therefore, this study aims to analyze the phytochemical constituents, traditional uses, and pharmacological activities of Ceratonia siliqua. Indeed, certain studies and research on pods and leaves of carob have revealed the presence of a number of compounds, including large amounts of carbohydrates, dietary fiber, minerals, polyphenols, flavonoids, and low amounts of protein and lipids. The secondary metabolite profile of carob extracts includes a matrix rich in polyphenols which is responsible for several biological effects and health attributes, namely, anticancer, antidiabetic, anti-inflammatory, antioxidant, antiulcer, anticonstipation, and antihyperlipidemic activities. So we finally concluded that carob had beneficial preventive and therapeutic properties.

The strawberry tree (Arbutus unedo L.) is a shrub (small tree) with evergreen leaves of the Ericaceae and is a main constituent of the flora of the Mediterranean basin. An increasing interest in the use of the strawberry tree (Arbutus unedo L., Ericaceae) has recently been reported in the industrial, pharmaceutical, and chemical fields. Indeed, some research on the fruits of Arbutus unedo has revealed the presence of several compounds, including large amounts of carbohydrates, dietary fiber, minerals, polyphenols, and flavonoids. In addition, the secondary metabolite profile of arbutus extracts includes a matrix rich in polyphenols, which is responsible for several biological activity and health attributes, namely antiseptic, diuretic, and laxative effects, and also to treat cardiovascular pathologies such as high blood pressure, atherosclerosis, and thrombosis.
