50. Percent extract yield in case of S. asoca and B. aristata were recorded maximum i.e. 12.5% & 12.02% respectively, where as in it is lowest in case of D. metel and P. pinnata i.e. 7.2%. Total sixty extracts of ten different PS-341 datasheet plants were screened for
antifungal activity using microbroth dilution assay (Table 1). Amphotericin B, the positive control used in this study shows MICs in the range of 0.73–1.95 μg/ml against fungal strains. Extracts with MIC equivalent of 5 mg/ml were categorized as low active extracts, with MIC from 2.5 mg/ml to 1.25 mg/ml are considered as optimally active extract and below 1.25 mg/ml are active extracts. Extracts with MIC above 5 mg/ml were reported to have no activity. Water extract of S. asoca showed maximum activity against A. fumigatus (0.65 mg/ml). The extracts with MIC ranging from 0.62 mg/ml to 2.5 mg/ml selleck screening library were further evaluated for their antifungal potential using disc diffusion assay. Extracts with MIC equivalent to 1.25 mg/ml and lower values were selected and used in disc diffusion assay with preset concentration of 25 μg/disc. Amphotericin B (2.5 μg/disc) is used as positive control. It was observed that only eight out of sixty plants extracts were found to be endowed with antifungal activity by disc diffusion assay (Table 2). Maximum zone of inhibition at this concentration was 8.0 ± 0.5 mm against A. fumigatus by water extract
of S. asoca. Extracts with MIC equivalent to 1.25 mg/ml and lower ( Table 3) were selected and evaluated by spore germination-inhibition assay. In MycoClean Mycoplasma Removal Kit conclusion, the results obtained in this study clearly demonstrate broad range antimicrobial activity of medicinal plants against fungi. Medicinal plants genetic variations study also explores their wide spectrum.9 The presence of phytocompounds in the extracts of medicinal plants has major active constituents which may be responsible for antifungal activity. Also the present study discloses the antifungal potential of medicinal plants varies with the species of the plants and solvents used for the extraction of phytoconstituents. UPLC-QTOFMS
based study of S. asoca plant was also explored its various extracts. 10 In future, the combined use of plant extracts and antibiotics could be also useful in fighting emerging drug-resistant problem.

“Delonix regia is a species of flowering plant grown as ornamental tree and given the name, flamboyant or flame tree, Gulmohar, Peacock, Royal poinciana. 1 In India it is known as Gulmohar, in according to Hindi and Urdu ‘Gul’ – means Flower, ‘Mohr’ means – Coin. 2 The D. regia can be commonly found in India, Mexico, Australia, Caribbean, Northern Mariana Islands, United Arab Emirates and South Florida. 3 Plant terpenoids can be used enormous for their aromatic qualities.
