PHYTOCHEMICAL SCREENING AND ANTI-TRICHOSPORON ACTIVITY OF PLUMBAGO ZEYLANICA LINN
Journal Title: International Journal of Pharmacy and Pharmaceutical Sciences - Year 2014, Vol 6, Issue 9
Abstract
Objective: To evaluate the anti-Trichosporon activity of a medicinal plant, Plumbago zeylanica Linn and to find out the phytochemicals responsible for this activity with the use of four solvent extracts; methanol, ethanol, acetone and chloroform.Methods: To evaluate the antifungal activity, two methods were used. Agar well diffusion assay to determine the diameter of zone of inhibition (in mm) and MIC (in mg/ml) was determined through Tube dilution broth assay. Phytochemical screening for preliminary analysis of secondary metabolites was done through chemical methods.Results: Trichosporon asahii was found to be most sensitive to methanol extract of P. zeylanica with inhibition zone of 35 mm and T. inkin with 30 mm zone of inhibition. MIC results also showed that the methanol extract was most effective in lowest concentration against T. asahii with MIC at 6.2 mg/ml and inhibited T. inkin at 25 mg/ml. Phytochemical screening of plant extracts revealed the presence of certain phyto-constituents like alkaloids, steroids, flavonoids, phenols, glycosides, tannins etc.Conclusion: The present study proved the sensitivity of the yeast Trichosporon spp. to different extracts of P. zeylanica. T. asahii was found to be more sensitive towards the extracts. Methanol extract proved to be most effective compared to ethanol, acetone and chloroform as it gave the maximum zones and lowest MIC result. Phytochemical analysis proved the presence of certain phytochemicals which was responsible for their antifungal activity.Â
