Medicinal plants have been frequently used to treat a variety of human diseases. Over the last century, the use of vegetation in medication has affected the identity of natural composites. One of the medicinal plants that have pharmaceutical values is Plantago ciliata Desf. This plant is commonly known as dil elkhrouf, Zelfana, annadam. This plant is belonging to the Plantaginaceae, is a traditional Algerian herbaceous plant abundantly distributed in the northeastern region of the Sahara. It has been reported to have numerous ethnopharmacological properties including anti-inflammatory, anti- ulcer, antitussive and anti-diabetic activities. Plantago genus is a vital medicinal plant that has many combinations of secondary metabolites. It has been used for the treatment of certain conditions such as hyperglycemia and high cholesterol levels. Additionally, the WHO has approved its use as a laxative agent. Nevertheless, relatively few studies have been conducted on the plant, including studies related to the genomic resources of the plant. Most Plantago species are perennial forages, lasting for many years, seemingly hairless, have a small root and several upright or curved stems that are equal to or slightly longer than the leaves and lack spaces. Its leaves are oval (the main type) with large veins and serrated ends, complete and relatively long petioles. Some of the Plantago plants are annuals, 5 to 20 cm tall, less stalked, more or less appressed hairy. Leaves resolute, narrowly oblong-lanceolate to linear-lanceolate. Scape thick, vertical or ascending, longer or shorter than the leaves. Spikes inflexible, very condensed, barely cylindrical, 3-10 cm. Fruit capsule, 3-5 seeds. The utilization of medicinal plants and their derivatives in treating illnesses is more appropriately recognized as herbal remedy than traditional medicine. For centuries, medicinal herbs have been used for the treatment of diseases in many countries.

Moringa oleifera, native to India, grows in the tropical and subtropical regions of the world such Africa.It is commonly known as ‘drumstick tree’ or ‘horseradish tree’. Moringa oleifera belonging to the family of Moringaceae is an effective remedy for malnutrition. Every part of this tree: Seeds, leaves, oil, sap, bark, roots, and flowers are widely used in traditional medicine. Moringa leaves have been characterized to contain a desirable nutritional balance, containing vitamins, minerals, amino acids, and fatty acids. Additionally, the leaves are reported to contain various types of antioxidant compounds such as ascorbic acid, flavonoids, phenolics, and carotenoids. Various preparations of M. oleifera are used for their antiinflammatory, antihypertensive, diuretic, antimicrobial, antioxidant, antidiabetic, antihyperlipidemic, antineoplastic, antipyretic, antiulcer, cardioprotectant, and hepatoprotectant activities. It also has been used to treat skin infections, anemia, anxiety, asthma, blackheads, blood impurities, bronchitis, catarrh, chest congestion, cholera and many other illnesses. This review explores the use of moringa across disciplines for its medicinal value and deals with cultivation, nutrition, and prominent pharmacological properties of this “Miracle Tree”.

Medicinal plants are considered rich sources of secondary compounds, and many modern medications are derived from them. Santolina is the most diverse genus within the mint family (Asteraceae), that is widely distributed in the Mediterranean basin and many of its species are well-known due to their medicinal and culinary uses. The present research discusses the traditional uses, phytochemical components and biological activities of Santolina rosmarinifolia. To do so, we carried out a comprehensive review of the articles available in different online databases published from the past to 2022 (i.e., PubMed, Scopus, and Web of Science, among others). S. rosmarinifolia has several traditional uses, including as anti-inflammatory and an antimicrobial agent, among several others, ascribed to it. In Spain, S. rosmarinifolia’s flowerheads are traditionally used as antipyretic, anti-inflammatory, antihypertensive and hepatoprotective. In Algeria, this plant is used for the treatment of dermatoses. The same uses are also reported in Portugal. The phytochemical studies have revealed the presence of terpenes, including monoterpenes, eudesmane-type sesquiterpenes, germacrene-type sesquiterpenes, dammarane-type triterpenes, coumarins, and flavonoids as the main classes of constituents. A study carried out on santolina Essential oil showed existence of sabinene, β-pinene, myrcene, β-phellandrene, limonene, 1,8-cineole, artemisia ketone, terpinen-4-ol, capillene, ar-curcumene and β-eudesmol. Monoterpenes like β- phellandrene, limonene and 1,8-cineole are also identified. In conclusion, this studies provides much information about the interests of vegetal species: Santolina rosmarinifolia.

The extraction of plant materials can be done by various extraction procedures. Non- conventional methods, which are more environmentally friendly due to reduced use of synthetic and organic chemicals, reduced operating time, and higher yield and quality of extract, have been developed over the past 50 years. A search carried out on the PubMed database using the following keywords: supercritical fluid extraction, lavender. This research showed seven studies out of 415 have begun to study the biological activities of lavender, using the method of supercritical fluid extraction and ultrasound-assisted extraction. The result shows that the effect of temperature and pressure on the extraction yield is highly pronounced. To be the optimum conditions to achieve the maximum yield and maximum polyphenols content in scCO2 extract from Lavandula. Further advantages of supercritical fluid extraction are the lack of oxygen which prevents unfavorable oxidation processes and the ease of separating the extractant from the product. Besides, the extracts obtained with supercritical fluids and ultrasound-assisted extraction showed a higher antimicrobial and DPPH scavenging activities compared with maceration extracts. This improved final product with the application of green technology could have potential applications in food, cosmetic and pharmaceutical industries as a preservative or nutraceutical.
