  • inhibition of penicillium digitatum and penicillium italicum by hydroxypropyl methylcellulose lipid edible composite films containing food additives with Antifungal Properties
    Journal of Agricultural and Food Chemistry, 2008
    Co-Authors: Silvia Valenciachamorro, Lluis Palou, Maria B Perezgago
    Abstract:

    New hydroxypropyl methylcellulose (HPMC)−lipid edible composite films containing low-toxicity chemicals with Antifungal Properties were developed. Tested chemicals were mainly salts of organic acids, salts of parabens, and mineral salts, classified as food additives or generally recognized as safe (GRAS) compounds. Selected films containing food preservatives were used for in vitro evaluation (disk diameter test) of their Antifungal activity against Penicillium digitatum (PD) and Penicillium italicum (PI), the most important postharvest pathogens of fresh citrus fruit. Mechanical Properties and oxygen (OP) and water vapor permeabilities (WVP) of selected films were also determined. Film disks containing parabens and their mixtures inhibited PD and PI to a higher extent than the other chemicals tested. Among all organic acid salts tested, potassium sorbate (PS) and sodium benzoate (SB) were the most effective salts in controlling both PD and PI. The use of mixtures of parabens or organic acid salts did not...

Film disks containing parabens and their mixtures inhibited PD and PI to a higher extent than the other chemicals tested. Among all organic acid salts tested, potassium sorbate (PS) and sodium benzoate (SB) were the most effective salts in controlling both PD and PI. The use of mixtures of parabens or organic acid salts did not provide an additive or synergistic effect for mold inhibition when compared to the use of single chemicals. Barrier and mechanical Properties of films were affected by the addition of food preservatives. Results showed that HPMC-lipid films containing an appropriate food additive should promise as potential commercial Antifungal edible coatings for fresh citrus fruit.

  • green synthesis and chemical characterization of silver nanoparticles obtained using allium saralicum aqueous extract and survey of in vitro antioxidant cytotoxic antibacterial and Antifungal Properties
    Applied Organometallic Chemistry, 2019
    Co-Authors: Mohammad Mahdi Zangeneh, Shabnam Bovandi, Sepideh Gharehyakheh, Akram Zangeneh, Parisa Irani
    Abstract:

    Allium saralicum R.M. Fritsch has been used in Iranian traditional medicine as a remedial supplement for microbial diseases. This paper reports the green synthesis, chemical characterization and antioxidant, cytotoxic, antibacterial and Antifungal Properties of silver nanoparticles obtained using aqueous extract of A. saralicum leaves. In this synthesis, no surfactants or stabilizers were used. For characterization, UV-visible spectroscopy, transmission electron microscopy, X-ray diffraction, energy-dispersive X-ray spectroscopy and field emission scanning electron microscopy were used. 2,2-Diphenyl-1-picrylhydrazyl was used in experiments to assess the antioxidant potential of the silver nanoparticles, which revealed an impressive prevention in comparison with butylated hydroxytoluene. The synthesized silver nanoparticles at low doses (1-250 mu g dl(-1)) did not show marked cytotoxic activity (against cervical cancer cells (Hela), breast cancer cells (MCF-7) and human embryonic kidney cells (HEK-293)). Agar diffusion tests were applied to determine the antibacterial and Antifungal characteristics. Compared with all standard antimicrobials, the silver nanoparticles showed higher antibacterial and Antifungal activities (p <= 0.01). Also, the silver nanoparticles inhibited the growth of all bacteria and fungi at concentrations of 31-250 mu g ml(-1), and destroyed them at concentrations of 31-500 mu g ml(-1) (p <= 0.01). Because the silver nanoparticles obtained using aqueous extract of A. saralicum leaves have antioxidant, non-cytotoxic, Antifungal and antibacterial potentials, they can be used as a medical supplement or drug.

  • chemical characterization and antioxidant cytotoxic antibacterial and Antifungal Properties of ethanolic extract of allium saralicum r m fritsch leaves rich in linolenic acid methyl ester
    Journal of Photochemistry and Photobiology B-biology, 2019
    Co-Authors: Ali R Jalalvand, Mohammad Mahdi Zangeneh, Akram Zangeneh, Mohsen Zhaleh, Samaneh Goorani, Niloofar Seydi, Rohallah Moradi
    Abstract:

    Abstract The purpose of the recent research was to assess the chemical characterization and antioxidant, cytotoxic, antibacterial, and Antifungal effects of Allium Saralicum R.M. Fritsch leaves. After identification of the plant, its ethanolic extract was obtained using Soxhlet extractor without leaving any chemicals in it. Gas chromatography-mass spectrometry (GC/MS) was performed to detect the percentage, retention index, and time of A. Saralicum compounds. Agar diffusion tests were applied to determine the antibacterial and Antifungal characteristics. In agar disk diffusion test, dimethyl sulfoxide (DMSO) was used as negative control, while antibacterial (Difloxacin, Chloramphenicol, Streptomycin, Gentamicin, Oxytetracycline, Ampicillin, and Amikacin) and Antifungal (Fluconazole, Itraconazole, Miconazole, Amphotericin B, and Nystatin) antibiotics were used as positive controls. Macro broth tube test was run to determine Minimum Inhibitory Concentration (MIC). The findings indicated that linolenic acid, methyl ester was the most frequent constituent found in A. Saralicum. Indeed, A. Saralicum showed higher antibacterial and Antifungal Properties than all standard antibiotics (p ≤ .01). Also, A. Saralicum prevented the growth of all bacteria and fungi at 15–125 mg/mL concentrations and destroyed them at 15–250 mg/mL concentrations (p ≤ .01). DPPH free radical scavenging test was carried out to examine the antioxidant effect, which indicated similar antioxidant activity with butylated hydroxy toluene (BHT) as a positive control. The synthesized ethanolic extract had great cell viability dose-dependently and demonstrated this method was nontoxic for synthesizing A. Saralicum. In conclusion, the findings showed the useful antioxidant, non-cytotoxic, antibacterial, and Antifungal effects of A. Saralicum ethanolic extract.
