    STUDY OF ANTIBACTERIAL ACTIVITY OF ZIZIPHUS SATIVA
    (UMT.lahore, 2017) SAHER FATIMA
    The scientists select the different plants for screening their components that helped to control the bacterial growth. Ziziphus sativa belonged to “Rhamnaceae” family. The common name of ziziphus sativa is berry in Persian it is known as ziziphus lotus. Ziziphus sativa is traditionally important medicinal plant. The antibacterial activity of ziziphus sativa was checked by the disc agar diffusion method. Four different solvents extracts (n-hexane, chloroform, ethyl acetate and aqueous) was used to check the antibacterial effect. Two gram negative bacteria (Escherichia coli, Klebsiella pneumoniae) and three gram positive bacteria (Staphylococcus aureus, Streptococcus mutans, Streptococcus pseudopneumoniae) were used to analyzed the antibacterial effect. All the strains showed antibacterial effect except Streptococcus mutans. While the ethyl acetate showed the best result among all extracts. Ethyl acetate showed 70mm zone of inhibition in 1% of plant extract while n-hexane extract showed no results against Klebsiella pneumoniae, Staphylococcus aureus, Streptococcus mutans and Streptococcus pseudopneumoniae strain. So it is concluded that ethyl acetate, chloroform, aqueous and n-hexane extract of ziziphus sativa can be served as antibacterial agent.
