    (Mdpi, 2019) Salehi, Bahare; Zakaria, Zainul Amiruddin; Gyawali, Rabin; Ibrahim, Salam A.; Rajkovic, Jovana; Shinwari, Zabta Khan; Khan, Tariq
    Piper species are aromatic plants used as spices in the kitchen, but their secondary metabolites have also shown biological effects on human health. These plants are rich in essential oils, which can be found in their fruits, seeds, leaves, branches, roots and stems. Some Piper species have simple chemical profiles, while others, such as Piper nigrum, Piper betle, and Piper auritum, contain very diverse suites of secondary metabolites. In traditional medicine, Piper species have been used worldwide to treat several diseases such as urological problems, skin, liver and stomach ailments, for wound healing, and as antipyretic and anti-inflammatory agents. In addition, Piper species could be used as natural antioxidants and antimicrobial agents in food preservation. The phytochemicals and essential oils of Piper species have shown strong antioxidant activity, in comparison with synthetic antioxidants, and demonstrated antibacterial and antifungal activities against human pathogens. Moreover, Piper species possess therapeutic and preventive potential against several chronic disorders. Among the functional properties of Piper plants/extracts/active components the antiproliferative, anti-inflammatory, and neuropharmacological activities of the extracts and extract-derived bioactive constituents are thought to be key effects for the protection against chronic conditions, based on preclinical in vitro and in vivo studies, besides clinical studies. Habitats and cultivation of Piper species are also covered in this review. In this current work, available literature of chemical constituents of the essential oils Piper plants, their use in traditional medicine, their applications as a food preservative, their antiparasitic activities and other important biological activities are reviewed.

    Plants of the genus Spinacia: From bioactive molecules to food and phytopharmacological applications
    (Elsevier Science London, 2019) Salehi, Bahare; Tumer, Tugba Boyunegmez; Ozleyen, Adem; Peron, Gregorio; Dall'Acqua, Stefano; Rajkovic, Jovana; Naz, Rabia
    Background: Spinacia plants, including the most recognized species of the genus Spinacia oleacea L. (spinach), have high nutritional value and high content in phytochemicals, such as flavonoids, polyphenols, carotenoids, and ascorbic acid. However, the amount of these phytochemicals depends on several factors, such as genotype, climatic conditions, and agronomic practices, harvesting, storage temperature and time. Scope and approach: This review focus on the therapeutic role of Spinacia genus as well as its contribution as food in industry. A special emphasis is also given to its biological activities including antioxidant and antimicrobial effects. Finally, the clinical efficacy of Spinacia plants, the respective roles, and mechanisms of bioactive compounds on human health are covered. Key findings and conclusions: Spinacia plants are rich in nitrate, thylakoids, glycoglycerolipids and their natural antioxidant mixture (NAO) shows renowned antioxidant, antiproliferative, anti-inflammatory, antimicrobial, anticancer and cardioprotective effects. Thus, the nutritional value and phytochemical composition of Spinacia plants make them an excellent matrix to be used in traditional medicine as also as a natural preservative ingredient in food.
