Abstract

Bukkol (Ziziphus mauritania Lam) has potential as bioactive compounds. The present research aims to investigate the phytochemical screening and antibacterial activity of the crude ethanolic extract of Ziziphus mauritania Lam against E. coli and S. aureus. The concentration of ethanolic extract of Ziziphus mauritania Lam leaves were 1%, 10%, 20%, 30%, and 40%. The method analyzed by the paper disc method (agar plate). The result of phytochemical screening shown that extract of Ziziphus mauritania Lam leaves has the detectable amount of secondary metabolites like flavonoids, tannins, saponins, and steroids. The result of ethanolic extract of Ziziphus mauritiana Lam leaves against S. aureus with the concentration of 1%, 10%, 20%, 30% and 40% indicating antibacterial activity which are 0 mm; 0, 92±0,056 mm; 1, 22±0,021 mm; 1, 36±0,017 mm and 1, 68±0, 03 mm. While extract of Ziziphus mauritania Lam leaves has no antibacterial activity against E. coli growth.
