ABSTRACT
The present study aimed to explore the biocomponents of Murraya koenigii leaves through hot continuous percolation method using methanol as solvent. The spectral analysis by GC-MS and FTIR study demonstrated the presence of alkaloids, tannins, fatty acids, and steroids. The extract was characterized by the presence of unique compounds such as epiyangambin, stigmasterol, α-terpineol, eucalyptol, ethyl cinnamate, fatty acids, and other steroids.

Seaweeds constitutes an abundant marine reserve that can be harnessed as source of new pharmaceutical agents. Sargassum binderi Sonder ex J. Agardh is a brown seaweed that is predominantly available from December to March in the Red Sea, Jazan, Kingdom of Saudi Arabia (KSA). In this study, three extracts were isolated using three different techniques, and were subjected to antibacterial assay. The petroleum ether extract of Sargassum binderi was more effective against selected human pathogenic bacteria than the other extracts. Therefore, further studies were focused on developing oleic acid vesicles entrapped with the petroleum ether extract of Sargassum binderi, with the aim of enhancing its penetration property. Oleic acid vesicles were prepared by entrapping petroleum ether extract of Sargassum binderi using film hydration technique. The formulated vesicles were in nanoscale, and so were termed phyto-nanovesicles (PNVs). The spectrum of antibacterial activity of PNVs showed that it is a promising formulation against S. aureus, S. pyogenes, B. subtilis, E. coli, K. pneumoniae and P. aeruginosa. The microbial sensitivities to the PNVs was in the order E.coli > B. subtilis > S. aureus > S. pyogenes > K. pneumoniae > P. aeruginosa. Thus, the PNV formulation possesses promising and effective antimicrobial potential against human pathogenic bacteria
