Fungitoxic studies on bark extract of Lawsonia inermis against ringworm fungi.

Abstract

During screening of barks of 30 plants species against Microsporum gypseum and Trichophyton mentagrophytes, only Lawsonia inermis exhibited absolute toxicity. The Lawsonia bark extract was found to possess fungistatic nature at its maximum inhibitory dilution of 1:30 (W/V) against both the test pathogens but, become fungicidal at 1:10 (W/V). The extract showed broad fungitoxic spectrum when tested against 13 ring worm fungi. Further the fungitoxicity of the extract remained unaltered at high temperature, on autoclaving and after long storage.
