ABSTRACT
The global scenario is now supporting the development of modern drugs from less toxic plant products with proven medicinal properties. Each part of the neem plant (Azadirachta indica A. Juss) reportedly has various medicinal properties and has been in use in many continents for centuries. In this project work, water extract from Neem leaves (Azadirachta indica A Juss) with the modern atomic absorption spectrophotometer was presented. The mineral and chemical properties in the water extract of Neem leaf were studied. Results showed that the neem leaf contains some essential minerals needed by the biochemical system. It is obvious that the water extract of Azadirachta indica is significantly high in sodium ion (Na+) and potassium ion (K+) concentrations which are responsible in the conduction of impulses along the axons of the central nervous system. Iron is another element determined. This element is significantly low in the water extract of the sample used (neem leaf).
