“…Increasing evidences have shown that natural products can be useful to reach a proper biological control of plant pests, attributed to the presence of several secondary metabolites, which control the disease up to an extent. Plant-derived phytochemicals, like saponins, alkaloids, terpenoids, flavonoids, tannins, and cardiac glycosides, have shown excellent antifungal properties against pathogenic fungi [7][8][9][10][11].…”

“…Various concentrations (1-7%) of methanolic extracts were prepared and checked against A. rabiei. 7% concentration exhibited strong antifungal activity up to 68% against test fungus [8]. It was reported that antimicrobial property of C. album was due to presence of saponins, flavonoids, alkaloids, phenolics, ascorbic acids, calcium, phosphate, minerals, salts, and protein [12].…”

Medicinal plants are composed of a rich pool of biomolecules and have been increasingly recognized for their antimicrobial properties; however, increasing concerns have been put on the bioavailability features. Thus, this study is aimed at exploring the synthesis and characterization of silver nanoparticles synthesized by Chenopodium album L. leaf extract and assessing the antifungal activity against Aspergillus terreus Thom. Plant extract was prepared in methanol to synthetize silver nanoparticles, which were then characterized by Scanning Electron Microscopy (SEM), UV-Visible spectroscopy, and particle size analysis. UV-Visible analysis indicated maximum absorption at 378 nm, and an average particle size was observed as 25.6 nm. Oval to hexagonal shape was observed by SEM. Antifungal activity of silver nanoparticles (1, 1.5, 2, 2.5, 3, and 3.5%) was addressed against A. terreus biomass. At 3.5%, silver nanoparticles revealed to be highly effective, leading to 92% retardation in fungus growth. In next phase, various organic fractions, viz., chloroform, n-butanol, n-hexane, and ethyl acetate, were obtained from plant methanol extract, and the corresponding silver nanoparticles were prepared. These fractions were also assessed for antifungal activity, and n-hexane fraction led to 64% inhibition in A. terreus biomass. Following gas chromatography-mass spectrometry (GC-MS), 18 compounds were identified, namely, 1,3-cyclopentadiene-5-(1 methylethylidene and o-xylene), ethyl benzene, octadecane, nonane, decane, 2-methylheptane, n-hexadecane, 2-methylheptane, and eicosane, along with carbonyl compounds (4,4-dimethyl-3-hexanone) and phenols, like stearic acid, propionic acid hydrazide, and 2,4-di-T-butylphenol. These findings proved that C. album silver nanoparticles are highly effective against A. terreus.

“…Mass detector conditions were: ionization voltage 70 eV mass scanning range m/z 29-540 and source temperature 230 o C. The percentage composition of volatile compounds was computed from GC peak areas. Qualitative analysis was based on a comparison of retention times, indices and mass spectra with the corresponding data in the literature (NIST Library 2010 word software) (Sherazi et al, 2016) All the data were statistically analyzed by using analysis of variance (ANOVA) followed by Duncan's Multiple Range test (DMR) at Pd"0.05 (Steel et al, 1997).…”

In the current study phytochemical analysis and in vitro antifungal potential of fruits, leaves and stem of Lantana camara L. were studied. The phytochemical analysis indicated the presence of alkaloids, flavonoids, tannins, saponins, glycosides and terpenoids in fruit, stem and leaves of L. camara. The in vitro antifungal activity of fruit, stem and leaves of L. camara was tested against Colletotrichum gloeosporioides Penz. Different concentrations (1-5%) of methanolic extract of all the selected parts of L. camara were applied in vitro against the test fungus. The results of in vitro experiment revealed that higher concentration of methanolic fruit extract (5%) significantly reduced the biomass C. gloeosporioides up to 66%. This effective extract of L. camara was partitioned with n-hexane, chloroform, ethyl acetate and n-butanol. The bioactivity of these fractions was tested against C. gloeosporioides. The trials showed that 0.5% concentration of n-hexane fraction of methanolic fruit extract caused the highest reduction (45%) in the radial colony growth of the test fungus. This effective n-hexane fraction was selected for GC-MS analysis to identify various possible antifungal compounds. Cyclopropane, carboxylic acid, 5-heptonic acid, 2,2-dimethyl1-4-pentenoate and 2-Propyloctahydro-1-benzothiophene were identified as major compounds. This study can be concluded that L. camara fruit comprised of bioactive compounds which possess antifungal activity against C. gloeosporioides.

“…This partitioning resulted in the gummy mass of n-hexane (1.56 g), chloroform (2.66 g), ethyl acetate (2.23 g) and n-butanol (1.86 g). All the four fractions were serially diluted to check their bioactivity against the target fungus by following the protocol of Sherazi et al (2016).…”

Mango (Mangifera indica) is one of the most important trees grown mainly in the tropical and subtropical countries. Anthracnose disease caused by Colletotrichum gloeosporioides, is the most damaging disease causing reduction of flower set and yield losses in mango. The present study was designed to evaluate antifungal activity of Datura metel extracts against C. gloeosporioides. Extracts (1% to 3%) of different parts of D. metel viz. leaves, seeds and roots were assessed for their antifungal potential. Methanolic seed extract of D. metel depicted the highest antifungal potential against the test fungus. All the applied concentrations effectively reduced growth of the test fungus. However, 1.5% conc. of methanolic seeds extract showed maximum reduction (80%) in comparison with control. This extract was further subjected to fractionation using various organic solvents viz. n-hexane, chloroform, ethyl acetate and n-butanol. Chloroform fraction was proved to be the best for the inhibition of the target fungus that was analyzed by GC-MS and various bioactive constituents like n-hexadecanoic acid, phytol, octadecanoic acid, oleic acid, o-xylene and cyclohexanol were identified.
