Psidium guajava is a tropical evergreen tree. It belongs to the family Myrtaceae that consists of about 133 genera and approximately 3800 species worldwide. This plant is mainly found in South Africa, North Africa, South America, and Southeast Asia. Psidium guajava is mainly a nutritional plant, but it also shows various biological activities. An array of bioactive constituents, viz; glycosides, terpenoids, tannins, alkaloids, steroids, saponins, amino acids, anthraquinones, proteins, flavonoids, and phenols, etc. have been isolated from Psidium guajava. These phytochemicals are well known for their biological activities, including antibacterial, antioxidant, antifungal, etc. The present work has been performed to gather data about the traditional uses, important phytochemicals, and antibacterial efficiency of Psidium guajava. Many pharmacological studies have demonstrated its antibacterial potential against various important drug resistive pathogens. We invite researchers' attention to carry out detailed antibacterial studies on this valuable plant species to provide reliable knowledge to the patients and discover more novel compounds for the development of new drugs with fewer side effects compared to conventional medicines.

Cinnamon has been used as a spice, condiment, and aromatic plant since centuries ago. Cinnamon is a small evergreen tree belonging to the genus Cinnamomum in the family Lauraceae. There are more than 250 species of cinnamon worldwide. In India, Cinnamomum verum and Cinnamomum cassia are the most common species grown in the Himalaya region. They have been used as folk medicine for the treatment of nausea, flatulent dyspepsia, coughs, diarrhea, malaria, gastric disorder, and to alleviate pain and inflammation in rheumatic arthritis. Therapeutic properties of cinnamon are due to the presence of bioactive constituents such as p-coumaric, cinnamaldehyde, cinnamic acid, and eugenol. Cinnamaldehyde and eugenol are the major active constituents responsible for its characteristic flavor, aroma, and therapeutic properties. Pharmacological studies found that it could be a promising candidate with potential for designing new drugs. This review is aimed to summarize the ethanomedicinal importance, phytochemistry, and wide spectrum of pharmacological and therapeutic applications of cinnamon.

AbstractThe genus Santolina is a taxonomically complex group of plant species widely distributed in the Mediterranean flora and used in traditional medicine since ancient times for their biological properties, including antimicrobial, anti-inflammatory, antispasmodic, digestive, and analgesic activities. Phytochemical investigations of Santolina species have revealed the presence of terpenoids as the main bioactive constituents of the genus. Coumarins and flavonoids were also identified. This review deals, for the first time, with information on the traditional uses, chemical profile, and biological properties of plants of the genus Santolina in order to provide input for future research prospects.

Marine sponges are exceptionally prolific sources of natural products for the discovery and development of new drugs. Until now, sponges have contributed around 30% of all natural metabolites isolated from the marine environment. Family Latrunculiidae Topsent, 1922 (class Demospongiae Sollas, 1885, order Poecilosclerida Topsent, 1928) is a small sponge family comprising seven genera. Latrunculid sponges are recognized as the major reservoirs of diverse types of pyrroloiminoquinone-type alkaloids, with a myriad of biological activities, in particular, cytotoxicity, fuelling their exploration for anticancer drug discovery. Almost 100 pyrroloiminoquinone alkaloids and their structurally related compounds have been reported from the family Latrunculiidae. The systematics of latrunculid sponges has had a complex history, however it is now well understood. The pyrroloiminoquinone alkaloids have provided important chemotaxonomic characters for this sponge family. Latrunculid sponges have been reported to contain other types of metabolites, such as peptides (callipeltins), norditerpenes and norsesterpenes (trunculins) and macrolides (latrunculins), however, the sponges containing latrunculins and trunculins have been transferred to other sponge families. This review highlights a comprehensive literature survey spanning from the first chemical investigation of a New Zealand Latrunculia sp. in 1986 until August 2020, focusing on the chemical diversity and biological activities of secondary metabolites reported from the family Latrunculiidae. The biosynthetic (microbial) origin and the taxonomic significance of pyrroloiminoquinone related alkaloids are also discussed.

The health benefits and toxicity of plant products are largely dependent on their secondary metabolite contents. These compounds are biosynthesized by plants as protection mechanisms against environmental factors and infectious agents. This review discusses the traditional uses, phytochemical constituents and health benefits of plant species in genus Zanthoxylum with a focus on cancer, microbial and parasitic infections, and sickle cell disease as reported in articles published from 1970 to 2021 in peer-reviewed journals and indexed in major scientific databases. Generally, Z. species are widely distributed in Asia, America and Africa, where they are used as food and for disease treatment. Several compounds belonging to alkaloids, flavonoids, terpenoids, and lignans, among others have been isolated from Z. species. This review discusses the biological activities reported for the plant species and their phytochemicals, including anticancer, antibacterial, antifungal, antiviral, anti-trypanosomal, antimalarial and anti-sickling properties. The safety profiles and suggestions for conservation of the Z. species were also discussed. Taken together, this review demonstrates that Z. species are rich in a wide range of bioactive phytochemicals with multiple health benefits, but more research is needed towards their practical application in the development of functional foods, nutraceuticals and lead compounds for new drugs.

Laurus nobilis L., commonly known as bay leaves, is native to the southern Mediterranean region. It is a small tree belonging to the genus Laurus of the family Lauraceae. The essential oils created from the different parts of this plant, such as the leaves and flowers, have been used in the food, drug, and cosmetic industries. The essential oil chiefly consists of 1,8-cineole, sabinene, α-pinene, and p-Cymene. Researchers have reported that bay leaves possess various biological and pharmacological properties, such as antibacterial, antifungal, antioxidant, insecticidal, and nematicidal activities. Pharmacological studies found that bay leaf oil could be a promising candidate with the potential for designing new drugs. The goal of this review is to summarize the ethnomedicinal importance, phytochemistry, and wide spectrum of pharmacological and therapeutic applications of bay leaves, which will be useful to researchers for further study.
