Spectrophotometric study of plant extracts of Nerium oleander, Conocarpus lancifolins, Eucalyptus camaldulensis Dehnh, Vicia and Jasminum Humile using set of different organic solvents

Abstract

Spectrophotometry scanning was conducted for plant extracts of Nerium oleander. Conocarpus lancifolins, Eucalyptus camaldulensis Dehnh, Vicia and Jasminum Humile. Spectrophotometric analysis methods (Ultra Violet and Visible rays) at range 200-800 nm were applied. Leaves were collected from different places at Nasiriyah city from March to April 2011. The cold extraction method was used through ethanol 95 %, acetone and petroleum ether. The aim of this study is to establish standard basic data about chemical composition of these extracts that could be used as a reference for other future studies
