to more efficient classes of antibiotics of natural origin. Plants have provided not only directly utilizable drugs, but also various compounds that can be used as starting steps for the synthesis of new drugs with better pharmacological properties (Mukherjee & Wahile, 2006). Therefore the necessity to develop new drugs requires varied strategies, among them, the bio prospection of secondary metabolites produced by medicinal plants (Dionisi et al., 2012 andShanmugam &Bhavani, 2014).
