Ziziphus oenoplia Mill.: A Systematic Review on Ethnopharmacology, Phytochemistry and Pharmacology of an Important Traditional Medicinal Plant.

BACKGROUND: Ziziphus oenoplia Mill. (Family- Rhamnaceae) an important shrub, often found throughout the hot regions of tropical Asia and northern Australia, is commonly well known as Jackal jujube in English. It is a folk herbal medicine used as an abdominal pain killer and antidiarrhoeal agent. OBJECTIVE: The review aims to provide up-to-date information on the vernacular information, botanical characterization, distribution, ethnopharmacological uses, pharmacological activities, and chemical constituents of Z. oenoplia for possible exploitation of treatment for various diseases and to suggest future investigations. METHODS: This review was performed by studying online resources relating to Z. oenoplia and diverse resources, including scientific journals, books, and worldwide accepted databases from which information was assembled to accumulate significant information and relevant data in one place. RESULTS: Investigations on Z. oenoplia have been focused on its pharmacological activities, including its antimicrobial, antidiabetic, antihepatotoxic, antiulcer, antiplasmodial, anticancer, wound healing, anthelmintic, antioxidant, analgesic and antinociceptive, hypolipidemic activity, anti-inflammatory, immunomodulatory and antidiarrheal activities. Phytochemical studies resulted in the isolation of fatty acids, flavonoids, phenols, pentacyclic triterpenes, hydroxycarboxylic acids, aliphatic hydroxy ether, and cyclopeptide alkaloids. CONCLUSION: Most of the ethnopharmacological relevance of Z. oenoplia is justified, but more studies are needed. Further investigations are necessary to fully understand the mode of action of the active constituents and to exploit its preventive and therapeutic potentials.

Phytochemistry, Traditional Uses and Pharmacological Properties of Enhydra fluctuans Lour: a Comprehensive Review.

BACKGROUND: Enhydra fluctuans Lour, a tropical herb, commonly known as helencha or harkuch, belongs to the family Asteraceae. It is an edible semi-aquatic herbaceous vegetable plant with serrate leaves and grows commonly in different parts of the world. Enhydra fluctuans possesses potential pharmacological role against inflammation, cancer, diarrhea, microbial infection, diabetes, etc. Aim: This review aims to provide the most current information on the botanical characterization, distribution, traditional uses, chemical constituents, as well as the pharmacological activities of Enhydra fluctuans Lour. MATERIALS AND METHODS: The recently updated information on Enhydra fluctuans was gathered from scientific journals, books, and worldwide accepted scientific databases via a library and electronic search PubMed, Elsevier, Google Scholar, Springer, Scopus, Web of Science, Wiley online library. All of the full-text articles and abstracts related to Enhydra were screened. The most important and relevant articles were carefully chosen for study in this review. RESULTS: Crude extracts and isolated compounds of Enhydra fluctuans Lour have been reported to be pharmacologically active against cytoprotective, analgesic and anti-inflammatory, antimicrobial, anticancer, antidiarrheal, antihelmintic, CNS depressant, hepatoprotective, thrombolytic, antidiabetic, antioxidant, phagocytic and cytotoxic, and neuroprotective potential activities. DISCUSSION: Phytochemical analysis from different studies has reported Germacranolide, Sesquiterpene lactone, Flavonoid, Essential oil, Steroid, Diterpenoid, Melampolide, Sesquiterpene lactone, and Isoflavone glycoside as major compounds of Enhydra fluctuans Lour. CONCLUSION: However, more research is needed to explore the mode of action of bioactive components of the plant and its therapeutic capabilities.
