ABSTRACT
Medicinal plants form the backbone of traditional system of
medicine in India. Pharmacological studies have acknowledged the
value of medicinal plants as potential source of bioactive compounds.
Ethanolic extracts of Cassia auriculata were used traditionally in India
for the treatment of skin diseases. The present study was investigated
for invitro antimicrobial activity against pathogens namely
Staphylococcus aureus, Bacillus subtilis, Streptococcus pyogenes,
Pseudomonas auroginosa, Klebsiella pnemonia, Aspergillus nĂger,
Trichoderma viride and Candida albicans using the agar well diffusion
method. The results relevant that the plant leaf extract possessed the
highest inhibitory activity against the bacteria (Staphylococcus aureus
in 23 mm) and fungi (Candida albicans in 14 mm). Among the leaf
extracts of C. auriculata possess the highest inhibitory activity then the root extracts. In
parallel study was performed to identify the distribution and the concentration of the
phytocompounds in the roots and leaves of this plant. For this purpose we have prepared
alcoholic extracts from each part of the plant and we have studied them separately.
Keywords: Antimicrobial activity, Cassia auriculata, Phytochemical analysis.
