Ailanthus excels belongs to family Simaroubaceae known as tree of Heaven and Mahanimba commonly found in the India and China. The present study involves preliminary screening, qualitative analysis and pharmacological evaluation of extract. The preliminary photochemical screening performed using petroleum ether, chloroform and methanol extract. Analytical techniques like; TLC, FTIR and HPTLC also performed for qualitative and quantitative determination. Various chemical tests also performed for qualitative determination of alkaloids, flavanoids, phenols, terpenoids, steroids and saponins in plant extracts. Plant extract finally subjected to antibacterial and antifungal activities and findings of study suggested that plant extracts possesses potent antibacterial and antifungal activities. Keywords: Ailanthus excelsa, antibacterial, antifungal, preliminary screening, TLC, HPTLC.

Objective: The objective of the study was the preliminary screening of the methanolic leaf extract of Couroupita guianensis for various phytochemical constituents, its antioxidant, antibacterial, and antifungal activities. Methods: Phytochemical screening of 18 qualitative, 6 quantitative constituents, antioxidant activity, alpha-amylase inhibitory activity, and alpha-glucosidase inhibitory activity of the methanolic extract of the leaf of C. guianensis was performed adopting the standard protocols. The disk diffusion methods were used for assessing the antibacterial and antifungal activities of the extract. Results: The preliminary studies revealed the presence of alkaloids, saponin, flavonoids, phenol, tannin, and terpenoids in the methanolic extract of the leaf of C. guianensis. Potent antioxidant, free radical scavenging activity, and inhibitory activity against α-amylase and α-glucosidase activity of the methanolic extract were also evident. Conclusions: The preliminary studies in the methanolic extract of the leaf of C. guianensis are suggestive of the therapeutic potentials of the methanolic extract of leaves of C. guianensis.

Aim of present research was to evaluate the anti-bacterial, anti-fungal, anti-oxidant and multi-stress activities of a medicinal plant Mint Lemonade plant extract. Fresh mint was purchased from the nearest market. The samples were cleaned with distilled led water and its leaves, stem and roots were separated them all. The material was dried in shade at room temperature (24ºC). The three types of extracts were prepared for each sample of mint plantviz, ethanol, n-hexane and water. The antibacterial and antifungal activities of ethanolic, n-haxene and aqueous mint extract was determined on Escherichia coli, Bacillus cereus, Pseudomonas, Aeromonas hydrophila, Aspergillus niger, Aspergillus flavous and Rhizopus stolonifer respectively. From the results of the antibacterial and antifungal activities it was clear that the aqueous extract showed no inhibitory effect on test these microorganisms. In ethanolic extract of antibacterial activity Escherichia coli showed the maximum zone of inhibition with diameters of 3.90 cm at 50 µl dose. Bacilluscereus showed the zone of inhibition diameter 4.9 cm. Pseudomonas showed the maximum zone of inhibition in diameter 3.86mm.Aeromonas hydrophila expressed the maximum zone of inhibition in diameter 3.86mm. The n-hexane extracts antibacterial activity of E. coli, Bacillus cereus, Pseudomonas and Aeromonas hydrophila showed the zone of inhibition 3.86 cm, 4.5 cm, 7.90 mm and 4.71 cm respectively, while the positive control showed inhibition zone about 0.0 cm. The antifungal activity in n-haxene extract showed the maximum result in Aspergillus flavous 18 cm of the area of inhibition. In ethanol extracts antifungal activity showed the maximum result in Aspergillus flavous 4.8 cm of the zone of inhibition. The inhibitory action of mint plant extracts indicated that the plant may be used as potential antibacterial agent.

The chemical composition of the essential oil from flowers of Eringium triquetrum Vahl. collected in Sicily was evaluated by GC and GC-MS. The main components were pulegone (50.6%), piperitenone (30.5%) and menthone (7.0%). Comparison of this oil with other studied oils of Eringium species is discussed. The oil showed good antibacterial and antifungal activities against some microorganisms that infest historical art works.
