Abstract

A large number of plants possess medicinal properties  due to which they are used as therapeutic agents or an  active ingredient of a medicinal preparation. A sizeable  fraction of the population throughout the world depends  on traditional practices to fight against various  infections and diseases and nearly all of it involves the  use of plant extracts gathered from a vast diversity of  plants which may include Herbs, Shrubs, Trees,  Climbers or Creepers. In the present work, we have  attempted to study different characteristics of Brassica  juncea leaves in different solvents including ethanol,  methanol and distilled water, to understand its  antimicrobial and antioxidant activity. Brassica juncea  comes under the family Cruciferae and genus Brassica,  is an important Rabi season oilseed crop. Various tests  were carried out to estimate phytochemicals like  tannins, flavonoids, phenols, alkaloids, glycosides,  terpenoids, amino acids, steroids, anthroquinones, and  saponins. Methanol extract of plant leaves were came  out to be abundant in phenols and flavonoids. The  antioxidant activity of B. juncea was determined by  DPPH scavenging activity and it is revealed that  methanol extract of this plant leaves possess maximum  antioxidant activity. Antibacterial potential of plant  leaves extracts were determined in vitro by the help of  agar well diffusion method against Staphylococcus  aureus, Bacillus subtilis, Klebsiella pneumonia and  Escherichia coli. Results were also compared with  control (Piperacillin/Tazobactam). All the extracts of B.  juncea leaves showed appreciable antibacterial activity.
