Abstract

The present study profiled various chemical constituents from the ethyl acetate fraction of Kigelia africana fruit extract in a comparative manner using modern chromatographic methods coupled with mass spectrometric techniques. K. africana plant has a wide usage in folklore medicine for numerous ailments with the ethyl acetate fraction having high antifungal and anti-plasmodial activities. Dried fruits were extracted with ethanol and partitioned using ethyl acetate. The fraction was analyzed using GC–MS, GC-TOF-MS and UHPLC-TOF-MS/MS. Fifteen compounds consisting of 2-methoxy-4-vinylphenol, phenol-2,4-bis(1,1-dimethylethyl), - and 9,12,15-octadecatrienoic acid ethyl ester, (Z, Z, Z) – were obtained from GC–MS while 441 metabolites ranging from flavonoids, cardiac glycosides, and polyphenols were profiled from GC-TOF-MS whereas 235 metabolites were fingerprinted from UHPLC-TOF-MS/MS analysis by measuring m/z values and analyzing MS fragmentation pattern. From the identified phytochemicals through ultra-high-pressure liquid chromatography tandem mass spectrometer (UHPLC-TOF-MS/MS), 14 of them were confirmed and these include gemfibrozil, trimetazidine, and leucomalachite green.

Abstract

Emerging Freshwater Pollutants: Analysis, Fate and Regulations comprises of 20 chapters, all written by leading experts. This book is written in the most practical terms and is easy to understand, with numerous helpful examples and case studies and can be used as a practical guide and important educational tool on issues concerning freshwater emerging pollutants. The organisation of the book exposes the reader in logical succession to the full range of complex scientific and management aspects of emerging freshwater pollutants in the developing world. The book recognises that water chemistry, emerging freshwater pollutants and management are inter-dependent disciplines. The book covers (i) the different monitoring techniques, current analytical approaches and instrumental analyses, (ii) fate and occurrence of emerging pollutants in aquatic systems and (iii) management policies and legislations on emerging pollutants. Thus, subsequent chapters elucidate chemicals with pollution potential, multi-detection approaches to analysis of organic pollutants in water, microplastics effects and photochemical transformation of emerging pollutants in freshwater systems. Whereas, other chapters address oxidation of organic compounds in aquatic systems, biomonitoring systems for detection of toxic levels of water pollutants, and health aspects of water recycling practices. This book melds several different perspectives on the subject of freshwater emerging pollutants and shows the interrelationships between the various professions that deal with water quality issues. Further, within the presentation of each separate chapter is discussion of how the various scientific and management aspects of the subject interrelate. - Includes case studies and practical examples in each chapter - Presents a much-needed interdisciplinary approach, representing the overlap between water chemistry and emerging freshwater pollutants - Provides a thorough introduction to emerging tropical and freshwater pollutants that typically occur in these systems
