Phytochemical analysis and antimicrobial activity of coconut husk extract on various solvents

Abstract

Coconut is known as the “wonder food” and is regarded as perfect diet because it contains almost all essential nutrients needed by the human body. Coconut husk is a by-product of the coconut that known contains phytochemical compounds and antimicrobial activities. This study aims to determine the phytochemical characteristics and the antimicrobial activity of coconut husk extracts. Completely Randomized Design was used in this study and the effect of coconut husk and the different solvent type were investigated. These are selected Five different solvents, they are polar solvent and non-polar i.e. Acetone, Ethanol, Methanol, Chloroform and Petroleum ether. The phytochemicals characteristic and antimicrobial activity of coconut husk extract were determined. The results of this study indicated that coconut husk extract containing Carbohydrates, Reducing sugar, Sugar, Proteins, Tannins, Saponin, Flavonoids, Steroids. and terpenoids. The coconut husk extracts showed antimicrobial activity against Streptococcus cocci and E. coli and the microbes isolated from soil. The coconut husk extracted with Acetone show the highest antimicrobial activity. The highest antimicrobial activity against Streptococcus cocci bacteria with inhibition zone diameter of 10 mm, and the coconut husk extract with Ethanol show the lowest inhibition antimicrobial activity these are 04 mm against E. coli. The extract was observed to be more effective against Streptococcus cocci. Presence of tannins and other phenolic compound ds may responsible for antimicrobial activity.
