Antimicrobial activity of Heliotropium indicum Linn (Hatir Shur)

[jeasminsultana]

Phytochemical screening of the extracts showed the presence of
Alkaloids, saponins, tannins, glycosides and flavonoids while phlobotamins, steroids, coumarin
and cardiac glycosides are absent in all the crude extracts. The antimicrobial screening of the
extracts showed significant zones of inhibition against 70% of the test organisms. The Minimum
Inhibition Concentration (MIC), Minimum Bactericidal Concentration (MBC) and Minimum
Fungicidal Concentration (MFC) against various organisms were conducted. The antimicrobial
analysis of the isolated components was also conducted. These prove the folkloric usage of the
plant and also indicated a broad spectrum activity of the plant extracts.
