Phytochemical Screening and Antibacterial Activity of Solanum Trilobatum L. and Azadirachta Indica A

Abstract

Medicinal plants play a pivotal role in curing various human ailments. The incidence in the frequency of diseases due to pathogenic microorganisms has increased alarmingly due to the development of resistance to existing drugs and the present scenario necessitate the continuous search for new classes of antimicrobial agents preferably from natural resources. Phytochemicals are ecologically derived secondary metabolites synthesized by the plants from the primary metabolites such as carbohydrates, lipids and amino acids to protect them against environmental challenges such as UV- irradiation, extreme cold, drought, microbial attack, wound, sugar and nutrient deficiency. They often contribute to the unique odor, taste and color in plants. Diseases due to pathogenic microbes pose a great burden on human health and they have been correlated with socioeconomic, environmental, ecological factors. The threat due to infectious diseases is further intensified by the continued emergence of new and multidrug resistant microorganisms.
