Abstract

Aqueous and chloroform extracts of Heliotropium indicum were screened for phyto chemicals and antimicrobical activity against seven bacterial organism Klebsiella pneumoniae , Staphylococcus aureus, Staphylococcus epidermidis, Streptococcus pyogens, Serratia marcescens, Pseudomonas aeruginosa and Escherichia coli and five fungal organisms Aspergillus niger , Aspergillus fumigatus, Ganoderma lucida, Mucor indicus and Saccharomyces cervisiae by well diffusion method. The phytochemical analyses showed the presence of saponin, tannin, alkaloid, phenol and proteins. Among the two extracts assessed aqueous extract had significant inhibiting activity than chloroform extract. The maximum zone of inhibition was recorded Escherichia coli in bacterial strains and Ganoderma lucida was recorded in fungal strains. Key Words: , Heliotropium indicum, Phytochemical, Antimicrobial activity.
