Abstract

Annona muricata L. (A. muricata L.) or traditionally known as soursop is well known for its deliciously sweet sour taste of its fruits. The other parts of the tree also have been used in remedies in traditional medicinal history including the bark, leaves, and root, fruit, and fruit seeds. Previous research on A. muricata L. has focused on the bark of the tree and root for pharmaceutical purposes by testing it on laboratory animals. Little attention has been paid to the research on the leaves which actually possessed valuable phytochemical constituents that have the potential as antimicrobial properties in treating diseases that caused by some bacterial strains. The main objective of this study is to do phytochemical and antimicrobial activity screenings of the A. muricata L. leaves extract. The analysis result obtained had been compared to previous study done in other countries. The leaves of A. muricata L. collected randomly from rural area in Jerantut, Pahang. The process of extraction, screenings and analysis were done in Laboratory of Sekolah Pertanian Lestari, UMS Kampus Sandakan. The solvents used for the extraction of plants are aqueous, chloroform and ethanol. The in vitro antibacterial activity was performed by disc diffusion method and tested on bacteria strains which were three Gram negative; Escherichia coli, Salmonella enteritidis, Citrobader freundii along with one Gram positive bacteria which is Staphylococcus aureus. In this study, it was found that aqueous leaves extract gave the highest percentage of yield extraction. In phytochemical screening, the leaves extract showed the presence of glycoside, tannin, saponin and flavonoid. For antimicrobial activity screening, aqueous leaves extract showed the highest zone of inhibition on tested bacterial strains .The phytochemical and antimicrobial activity screenings suggest that A. muricata has antimicrobial properties.
