Abstract
A rapid untargeted UHPLC-Q-TOF-ESI-MS/MS-Based metabolomic profiling of the medicinal plant Entada abyssinica was performed. A total of 18 metabolites were detected, of which 10 could not be identified. Based on this result, an extensive chemical investigation of the CH2Cl2-MeOH (1:1) extract of this plant was carried out, leading to the isolation of a new ceramide, named entadamide (1), together with nine known compounds: monomethyl kolavate (2), 24-hydroxytormentic acid (3) chondrillasterol (4), 3-O-β-D glucopyranosylstigmasterol (5), 3-O-β-D glucopyranosylsitosterol (6), quercetin 3'-methylether (7), 2,3-dihydroxypropyl icosanoate (8), 2,3-dihydroxy-propyl 23-hydroxytricosanoate (9) and 2,3-dihydroxy-propyl 24-hydroxytetracosanoate (10). Their structures were elucidated by the analyses of their spectroscopic and spectrometric data (1D and 2D NMR, and HRESI-MS) in comparison with those reported in the literature. Furthermore, the crude extract and some isolated compounds were tested against non-ciprofloxacin resistant strains viz, Pseudomonas aeruginosa (ATCC 27853), Escherichia coli (ATCC 25922), Samonella thyphi (ATCC 19430) and Samonella enterica (NR4294). The tested samples demonstrated significant activity against all the tested bacteria (MIC values: 3.12-12.5 μg/mL).

Biological Activity and Chemical Composition of Detarium microcarpum Guill. and Perr-A Systematic Review. Adv Pharmacol Pharm Sci 2022; 2022:7219401. [PMID: 36254172 PMCID: PMC9569227 DOI: 10.1155/2022/7219401] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/25/2022] [Revised: 09/11/2022] [Accepted: 09/14/2022] [Indexed: 11/18/2022] Open
Abstract
Historically, natural products have been the principal source of medications for the treatment of human diseases. Traditional medical practitioners employ Detarium microcarpum as a treatment for diabetes, malaria, wounds, inflammation, and even cancer. This study emphasizes the importance of harmonizing D. microcarpum research so that results from various sources may be directly compared to reach a scientific conclusion. We searched Google Scholar, Science Direct, Google.com, Wiley, PubMed, Hindawi, and Springer for research papers on Detarium microcarpum. This analysis excludes untrustworthy online data, thesis papers, and review publications on D. microcarpum. The leaves and stem bark were shown to have high antioxidant, anti-inflammatory, antibacterial, antidiabetic, and anticancer properties. The study also discovered that too much consumption is harmful. Polyphenols and flavonoids were the most commonly reported compounds. However, human safety and efficacy are yet to be fully evaluated, and further well-designed clinical trials are needed to confirm preclinical findings. The leaves and stem bark extracts and isolated compound mechanism of action should be investigated. It is necessary to set a standard dose and ensure its safety.
