Abstract :
In the present study crude methanolic extract and various fractions (n-Hexane, chloroform, ethyl acetate and
aqueous) of Strobilanthes urticifolia Wall.ex Kuntze were used to investigate its antifungal and phytotoxic
properties. Antifungal assay was carried out against seven pathogenic fungal strains (Aspergillus niger, Fusarium
oxysporium, Triticum harzianum, Rhizopus stolonifera, Alternaria solani, Candida albicans, Microsporum canis)
using tube dilution method. The crude methanolic extract and various fractions showed low to good activities
against the fungal strains while only aqueous fraction showed significant activity against Candida albicans.
Phytotoxic assay was used to investigate the phytotoxic property of the plant extracts against the Lemna minor at
different concentrations (10,100 and 1000 µg/ ml) and showed highest phytotoxic activity at the concentration of
1000 µg/ml. The results obtained from in vitro studies of antifungal and phytotoxic activities clearly inferred that the
crude methanolic extract and various fractions of Strobilanthes urticifolia Wall.ex Kuntze have significant
properties against fungi and phytotoxic substances. For future perspective, extensive work will be needed, for the
isolation and characterization of active ingredients from S. urticifolia to facilitate its pharmacological assessment.
