Reduction of chemical in the air is of global concern. The study therefore explore some local dye producing plants, the best way to extract dye from them and the quantity of dye that can be extracted from a particular quantity of raw material. This may reduce the dependency of our fabric producing centres on the synthetic dyes that is chemically generated and it may conserve our dwindling foreign reserve.

The sample collection areas were Kaduna and Ogun state, eleven samples were randomly selected for pilot experiment and only three yielded different shade of colours. The three were guinea corn stalk, Henna dye and Pepper chew stick. Five organic solvents were tested for extraction at cold and hot temperature. The findings show that Ethanol is the best extraction solvent at both conditions. Hot extraction is faster while cold extraction yielded more dye and henna plant produced the highest dye quantity. ANOVA was used to analyse the differences in quantity of dye extracted from each plant and the temperature.

Nigeria has abundant dye producing plants which can be identified, extracted and preserved for use.
