RESUMEN
Ludwigia adscendens subsp. diffusa (Onagraceae), an important aquatic herb widely distributed in the Nile River and canals in Egypt. The goal of the current study is to investigate the phytochemical composition of L. adscendens aerial parts n-butanol and ethyl acetate fractions and screening of its biological activities. Phytochemical investigation of L. adscendens resulted in the isolation and purification of eleven compounds belonging to flavonoids, saponins, triterpenoids, and oligosaccharides, of which one compound was identified as new using different spectroscopic techniques. Compound 2 was identified as a new compound namely, 3-O-[ß-D-glucopyranoside (1 â 4) α-L-rhamnopyranoside]-23-O-feruloyl-hederagenin-28-O-[α-L-rhamnopyranoside (1 â 2) ß-D-glucopyranoside], along with other 10 well know compounds. Furthermore, antidiabetic, hepatoprotective and cytotoxic activities of n-butanol and ethyl acetate fractions were investigated in vitro, revealing that ethyl acetate fraction was the most active as antidiabetic (IC50 = 62.3 µg/mL), hepatoprotective (IC50 = 80.75 µg/mL), and cytotoxic against human prostate cancer cell line (IC50 = 52.2 µg/mL). Collectively, L. adscendens aerial part is rich with a myriad of phytochemicals with potential health benefits.
RESUMEN
Ludwigia stolonifera (Guill. & Perr.) P.H.Raven belonging to the family Onagraceae is an important aquatic herbal plant of economic importance in water bioremediation. We explored the compositional heterogeneity in the aroma profile of L. stolonifera aerial parts and roots. Volatile profiling was employed for the first time using volatile solvent extraction (VSE-GC-MS/MS) of both aerial parts and roots. A total of 85 volatiles were identified belonging to eight classes, viz., aliphatic, aromatic, and oxygenated hydrocarbons, monoterpenes, diterpenes, alcohols, acids/esters, and sterols. Aliphatic and aromatic hydrocarbons were found to be the most abundant metabolite groups in both aerial parts and roots. Furthermore, antioxidant and metal chelation activities of aerial parts and roots were investigated, revealing a potent activity as an antioxidant and high metal chelation capacity for heavy metals.
RESUMEN
ETHNOPHARMACOLOGICAL RELEVANCE: The Onagraceae is a widely distributed family of flowering plants comprises about 17 genera and more than 650 species of herbs, shrubs, and trees. Onagraceae also common as willowherb family or evening primrose family is divided into two subfamilies; Ludwigioideae (mainly genus; Ludwigia) and Onagroideae. Family Onagraceae is characterized by its numerous traditional uses as treatment of hormonal imbalances, urinary system ailments, prostate health maintenance, and antimicrobial effects. AIM OF THE STUDY: This review aims to introduce a holistic overview on the phytochemical composition, economical importance and ethnopharmacological value of different species of family Onagraceae. MATERIALS AND METHODS: Literature review was performed using different data bases such as PubMed, Web of Science, Google Scholar and Reaxys searching for articles focused on phytochemical composition, bioactivity and ethnopharmacological history of Onagraceae species. RESULTS: Different species of Onagraceae were reported to have a great variety of phytochemicals including flavonoids, tannins, phenolic acids, triterpenoids, saponins, and volatile/fixed oils. Onagraceae exhibited several health benefits and pharmacological activities including anti-inflammatory, antiarthritic and analgesic, antioxidant, cytotoxic, antidiabetic, and antimicrobial. CONCLUSIONS: Family Onagraceae is an extremely important family with diverse phytochemical composition which enriches their pharmacological importance and hence it's commercial and economical value.
