Hydraulic properties from pumping tests data of aquifers in Azare area, North Eastern Nigeria.

Abstract

Phytochemical analysis of the extracts from the leaves of the plant fleabane (Conyza sumatrensis) revealed the presence of some substances such as tannins, flavonoids, saponins, steroids and glycosides. The presence of these substances is an indicator of the pharmacological property as well as the nutritive value of the plant leaves. Antimicrobial tests showed that the leaves extract is not sensitive towards the bacteria Pseudomonas aureginosa, staphylococcus aureus, Bacillus spp and Escherichia coli, but inhibited the growth of the fungus Aspergilus niger. @ JASEM With the phenomenal growth in world population and the attendant depletion in food and drugs, mankind has to grapple with these problems by looking for alternative sources for these essentials of life.
