These extracts were used as samples in the qualitative analysis and preliminary screening for insecticidal property against termites. The screening of the ethanolic extracts from Acacia seeds and bark revealed the presence of saponin‚ tannins‚ alkaloids‚ reducing agents – glycosides‚ carbohydrates‚ which have the capacity to kill termites. The one-way Analysis of Variance (ANOVA) was used in comparing the means of the effect of the ethanolic extracts against termites. Results were positive‚ showing

No‚ o-nitrophenol will not react with ALP under optimum conditions obtained. This is because ALP is a hydrolase enzyme responsible for catalyzing the cleavage of a phosphate group from a variety of compounds including nucleotides‚ proteins‚ and alkaloids. Since o-nitrophenol doesn’t have phosphate group attached to it‚ so ALP will not react with it. CONCLUSION This chemical reaction is carried out by the enzyme ACP‚ Acid phosphate.Acid phosphatase is a phosphatase‚ a type of enzyme‚ used to
