Item Anti-Aging Potential of Bioactive Phytoconstituents Found in Edible Medicinal Plants: A Review(MDPI, 2024-06) Iweala, Emeka J.; Adurosakin, Oluwapelumi Eniola; Innocent, Ugochukwu; Omonhinmin, Conrad A.; Dania, Omoremime Elizabeth; Ugbogu, Eziuche A.Aging is a complex biological and physiological change that leads to a loss of function in all living organisms. Although the mechanism behind the aging process is still largely unknown, scientific studies have shown that oxidative stress and age-related low autophagy, which are associated with various chronic diseases such as cancer, diabetes, cardiovascular diseases, and neurodegenerative diseases, promote aging. Interestingly, many medicinal plants and their biologically active compounds have the ability to extend lifespan as they can inhibit oxidative stress and promote autophagy. This review evaluates and provides up-to-date information on the anti-aging potential of bioactive compounds in edible medicinal plants. In this study, seventeen (17) biologically active compounds from edible medicinal plants with anti-aging effects were reviewed. In vivo and in vitro studies showed that these biologically active compounds exhibit anti-aging effects via various mechanisms such as the activation of autophagy, increases in antioxidant enzymes, reductions in reactive oxygen species, the inhibition of inflammatory markers, and the downregulation of senescence genes. This study suggests that edible medicinal plants containing these bioactive compounds may promote health and extend lifespan. However, the exact mechanisms, effective doses, clinical trials, and chronic and genotoxic effects of bioactive compounds as anti-aging agents should be further investigated.Item Ethnopharmacological relevance, phytochemistry, potential health benefits and toxicity profile of Ananas comosus (L.) Merr (pineapple)(Pharmacological Research - Natural Products 10 ( Elsevier), 2026) Ugbogu, Eziuche A.; Iweala, Emeka Joshua; Ukachukwu, Chukwudi Eke; Babayo, Christy; Dania, Omoremime Elizabeth; Isreal, Chollom Longs; Omonhinmin, Conrad A.; Cleanclay, Wisdom D.; Okoro, Benedict ChukwuebukaIn traditional medicine, the cortexes of A. comosus are used as an alexipharmic, antitussive, and antidiarrheal agent, while the leaves are commonly used as a remedy for indigestion. This review provides a thorough and upto- date literature on the ethnopharmacological uses, phytochemistry, and potential health benefits of A. comosus. The articles used for this study were obtained from databases such as ScienceDirect, Frontiersin, PubMed, Springer, and MDPI. In addition, only articles written in English were included in this review. Phytochemical analysis revealed that A. comosus contains numerous biologically active compounds, including n-hexadecanoic acid, bromelain, n-heptadecanol-1, methyl ester, hexadecanoic acid, squalene, α-tocopherol, tetradecane, 5- hydroxymethylfurfural, dihydroxyacetone, dodecane, DL-α-tocopherol, furan methanol, dodecanoic acid, and 2,4,6-cycloheptatrien-1-one, among others. Various in vivo and in vitro biochemical studies have also shown that A. comosus possesses antioxidant, anti-inflammatory, anticancer, antidiarrheal, antimicrobial, antimalarial, cardioprotective, anthelmintic, and antidiabetic properties. Therefore, this review shows the biologically active compounds in A. comosus and the potential of different parts of A. comosus to prevent and treat various diseases. While A. comosus has shown promise in animal studies, human clinical trials are needed to determine safe and effective doses. Further research may reveal additional uses for this versatile plant as a functional food and in modern healthcare as a traditional and complementary alternative medicine.
