Abstract Synthesis of nanoparticles using marine algae extracts is the most adopted methods of green, eco-friendly production of nanoparticles and also has a special advantage that the Algae are widely distributed, easily available, much safer to handle and act as a source of several metabolites. In this thesis, eco-friendly tools based on marine algae extract is used for synthesis some metal nanoparticles. These green routes make applications of the synthesized nanoparticles in biomedical are possible. Taking the above into consideration, the current thesis was dealt with five-fold objectives, representing the five experimental chapters. In the first experimental chapter, the algal profiles embraced algae description, family and genus description, scientific classification and taxonomy of the red algae D. simplex, L. papillosa and G. oblongata and the brown alga T. decurrens were extensively mentioned. Second experimental chapter has dealt with chemical analysis, including qualitative and quantitative phytochemical screening, of the algal constituents. The results obtained indicated the presence of carbohydrates, protein, terpenes, phenolics and flavonoids. It deals with amino acids composition of selected algae, minerals analysis, saponifiable and unsaponifiable fractions, volatile constituent, halides analysis, polysaccharides analysis. These algae constituents are responsible for the synthesis of metal nanoparticles, nanosuspensions and microcapsules. Third experimental chapter concerned with investigation of the volatile constituents and petroleum ether extract of the four algae using the hydro-distillation method for volatile extracts. the volatiles constituents and petroleum ether extracts obtained were analyzed using GC/MS. Components of the volatile constituents and petroleum ether extracts were identified by comparing their retention times and mass fragmentation patterns with those of the libraries database and published data. Quantitative determination was carried out based on computerized peak area measurements. |
