CHAPTER ONE
1.0 INTRODUCTION AND LITERATURE REVIEW
1.1 INTRODUCTION
Medicinal plants represent a rich source of antimicrobials and many other drugs. The potentials of higher plants as source for new drugs is still largely unexplored. Antibiotic resistance has become a global concern (Westhet al., 2004). The clinical efficacy of many existing antibiotics is being threatened by the emergence of multidrug-resistant pathogens (Bandow, 2003). Many
infectiousdiseases have been known to be treated with herbal remedies throughout the history of
mankind. Natural products, either as pure compounds or as standardized plant extracts, provide
unlimited opportunities for new drug leads because of the unmatched availability ofchemical diversity.
There is a continuous and urgent need to discover new antimicrobial compounds with diversechemical
structures and novel mechanisms of action for new and re-emerging infectious diseases (Rojas et al.,
1992). Therefore, researchers are increasingly turning their attention tolocal herbs, looking for new
leads todevelop better drugs against microbial infections (Benkeblia, 2004).Phytochemical
The increasingfailure of chemotherapeutics and antibiotic resistanceexhibited by pathogenic microbial
infectious agents has led to the screening of several medicinal plants for their potential antimicrobial
activity (Kapila, 2005 ;Runyoro et al.,2006). The rising prevalence of antibiotics resistant pathogenic
microorganisms raises the demand for finding new alternative antimicrobial agents. The drugs already
in use to treat infectious diseaseare of concern because drug safety remains an enormous global issue.
Most of the synthetic drugscause side effects and also most of the microbesdeveloped resistant against
the synthetic drugs (Chanda and Rakholiya 2011). To alleviate this problem, antimicrobial compounds
frompotential plants should be explored. These drugs fromplants are less toxic; side effects are scanty
and alsocost effective. They are effective in the treatment ofinfectious diseases while
simultaneouslymitigatingmany of the side effects that are often associated withsynthetic antimicrobials
(Harishchandraet al., 2012).Phytochemical
