The oil which is plentiful in leaves has also been used against diabetes, cystitis, malaria, kidney disorders, leucorrhoea and laryngitis. The anticancer activity of this oil has been studied in vivo. The GC-MS analysis revealed the presence of 42 components. Major constituents are: eucalyptol […]

GC-MS Analysis and Antimicrobial Activity of Sudanese Acacia nubica Benth. (Fabaceae) Seed Oil

Abstract The present study was carried out to characterize the constituents of Acacia nubica seed oil and to assess the antimicrobial activity. Twenty five components were detected by GC-MS analysis being dominated by: 9,12-octadecanoic acid methyl ester (31.54%); 9-octadecanoic acid methyl ester(15.86%); hexadecanoic acid methyl ester (15.50%); methyl stearate (13.92%) and 9-octadecanoic acid methyl ester […]

Antimicrobial, Antioxidant and Cytotoxic Properties of Secondary Metabolites from Endophytic Fungi of Psidium Guajava

Abstract This study was undertaken to investigate the biological properties of secondary metabolites of two endophytic fungi (code names: GA and GC) isolated from Psidium guajava leaves. Isolation of the endophytic fungi, fermentation and extraction of fungal secondary metabolites was carried out using standard procedures. The fungal extracts were screened for antimicrobial, antioxidant and cytotoxic […]
