Abstract: Plants contain natural products which have been recognized as building blocks for primary health care. Sterculiar tragacantha Lindl, used traditionally in Nigeria for the treatment of boils, diarrhea, gonorrhea, edema, gout, whitlow, fevers and malaria is one of such plants. The prevalence of drug resistant pathogenic microbes as well as the oxidative damage to cells by excess free radicals that lead to degenerate diseases, constitute major health hazards to man. In this regard, extracts of the stem bark of S. tragacantha Lindl was investigated for their toxicity to brine shrimps and ability to scavenge hydroxyl radical and inhibit microbial growth. Air dried and ground stem bark of the plant was extracted with methanol and partitioned in n-hexane and ethyl acetate. Hydroxyl radical scavenging assay of the three extracts obtained revealed that the percentage inhibition for all the extracts was above 90% at 0.625 mg/ml which is higher than that of one of the antioxidant standard (ascorb

Abstract: The Centre for Biotechnology and Genetic Engineering (CBGE), University of Jos Artemisia annua L. Plantation situated at Gangnum, Langtang South Local Government of Plateau State, Nigeria has been unexplored particularly of its filamentous fungal diversity. This present study examined the diversity and abundance of filamentous fungi, pH, moisture and organic matter contents as well as elemental analysis of the Plantation soils which have stood uncultivated for years. Soil samples were collected (at a depth of 0-10 cm) from three locations selected randomly with cleaned and surface sterilized soil auger. The soil samples were collected on a monthly basis for 12months during both dry and rainy seasons. A total of 669 positive isolations were obtained. Of the number, 439 isolations were mesophilic, 109 were thermotolerant and 121 were thermophilic isolates. A total of 387 isolations were obtained during the dry season and 282 during the rainy season. The dry season had a higher diversity
