Rhanterium epapposum, native to the Arabian Peninsula, is traditionally used to cure skin infections. The objective is to screen the phytochemical content and antimicrobial activity of aqueous, methanol and 80% methanol extracts of aerial parts of R. epapposum. The phytochemical screening of aqueous, methanolic, and 80% methanol extracts of R. epapposum was conducted using gas chromatographymass spectrometry. The antimicrobial activities of the extracts were assessed by well diffusion and microdilution methods. Qualitative phytochemical analysis revealed the presence of 2-methoxy-4-vinylphenol in all three extracts, whereas ethanol, 2-methoxy-, acetate; n-hexadecanoic acid; and 2,3-butanediol are present in higher amount exclusively in the methanol, 80% methanol and aqueous extracts of the aerial parts of R. epapposum, respectively. The highest antibacterial activity was shown by the aqueous extract S. aureus, P. aeruginosa, E. cloacae, and K. pneumoniae, methanolic extract against S. aureus, methicillin-resistant S. aureus, and E. coli, and 80% methanol extract against S. epidermidis, and S. paucimobilis. Interestingly, 80% methanol extracts showed the highest antifungal activity against C. albicans, C. guillermondii, C. vaginalis, C. utilis, and C. tropicalis. The aerial parts of R. epapposum showed broad-spread antimicrobial activity against bacteria and fungi.

Ficus sycomorus L is a large, semi-deciduous spreading savannah tree that belongs to the family (Moraceae) is used by many tribes in the treatments of skin infections. The aim of this study was to carry out phytochemical analysis and antifungal evaluation of F. sycomorus L. stem and leaf Methanol extract on some dermatophytic fungi. The stem and leaf crude extracts were obtained after drying using maceration and percolation with methanol as the solvent. The extract was subjected to qualitative phytochemical screening as well as GC-MS analysis for the presence of bioactive constituents. The antifungal inhibitory effect of the crude stem and leaf extracts was assessed by agar well diffusion methods. The phytochemical screening revealed that the leaves and stem-bark contained secondary metabolites such as tannins, flavonoids, alkaloids, saponins, reducing sugar and steroid. The GC-MS assay showed that the most prevailing compound in the methanolic stem-bark extract was 2, 9, Diazabicyclo (4, 4, 0) decane-3,10 dione, while in the methanolic leaves extract was acetic acid. The anti-dermatophytic assay of the extracts against Microsporum canis and Tricophyton tonsurans showed that the extracts inhibited the fungi with zones of inhibitions ranging from 6.33±0.47 to 24.33±0.47mm with the leaf extract exhibiting higher inhibition zones than the stem extract (p˂0.01). The study shows that both the stem and leaf methanol extract of Ficus sycomorus L possesses antifungal activity and should be considered as a potential antifungal agent in search of newer agents to address dermatophytic fungal infections Key words: Ficus sycomorus L, Phytochemical/GC-MS Analysis, Antifungal activity

Antimicrobial activities and phytochemical screening of leaves of Mikania micrantha was tested in laboratory against phytopathogenic fungi and human pathogenic bacteria. The leaves samples were extracted in distilled water and methanol. The crude extracts of leaves were assessed in-vitro for antimicrobial activity using different concentrations (50, 100, 150,200, and 250 mg/ml) against five fungal strains (viz. Sclerotium rolfsii, Phytopthora capsici, Alternaria brassicae, Fusarium oxysporum and Botrytis cinerea) and six bacterial strains (Klebsiella pneumoniae, Proteus mirabilis, Escherichia coli, Bacillus subtilis, Enterococcusfaecalis and Staphylococcus aureus). Antifungal activity was tested by Poison Food Technique and Linear Mycelium growth Reduction (LMGR) percentage was determined. In crude extractof M. micrantha, the highest LMGR percentage was found in F. oxysporum in both distilledwater and methanol extract. Antibacterial activity was carried out by Disc Diffusion method. In the crude leaf extract of M. micrantha Gram negative bacteria was found more resistant than Gram positive bacteria. Methanol extract was found more effective in determining the Zone of Inhibition for all the strains of bacteria in all the concentrations. The plant extracts were found more effective in showing antibacterial activity than antifungal activity. The phytochemicalscreening revealed that the selected species contained tannin, saponins, alkaloid, flavonoid, cardiac glycosides and terpenoids. This result supports the potential of this plant species used as a new chemotherapeutic drug.

As part of our ongoing research on phytoconstituents that can act as promising antimicrobial agents, the essential oils of nine selected Apiaceae plants, cultivated in Poland, were studied. The volatiles of the aerial parts with fruits (herba cum fructi) of Silaum silaus, Seseli devenyense, Seseli libanotis,Ferula assa-foetida, Glehnia littoralis and Heracleum dulce, in addition to the fruits (fructi) of Torilis japonica and Orlaya grandiflora as well as of the aerial parts (herba) of Peucedanum luxurians were investigated through Gas Chromatography–Mass Spectrometry to identify more than 60 different metabolites. The essential oils from S. devenyense, H. dulce, T. japonica and P. luxurians are reported for the first time. All examined species were also assayed for their antimicrobial activities against several human pathogenic Gram-positive and -negative bacteria and fungi. The species H. dulce, S. devenyense and S. libanotis exerted the strongest antimicrobial activity, mostly against Gram-positive bacteria strains (MIC values 0.90–1.20 mg/mL). To the best of our knowledge, this is the first attempt to determine the antimicrobial activity of the above Apiaceae species.
