Aminal, Musarat published the artcileExploiting the potential of Moringa oleifera oil/polyvinyl chloride polymeric bionanocomposite film enriched with silver nanoparticles for antimicrobial activity, Recommanded Product: Methyl docosanoate, the main research area is Moringa Staphylococcus Escherichia Salmonella polyvinyl chloride polymeric bionanocomposite antimicrobial.

The present study focused on the prospect of fabricating a polymeric naturally extracted Moringa oleifera oil bionanocomposite film enriched with silver nanoparticles for antimicrobial activity. In this study, a standard concentration of Moringa oleifera oil (5-10 wt%) was used to fabricate a polymeric bionanocomposite film using polyvinyl chloride (PVC) enriched with silver nanoparticles. The active constituents of the extracted Moringa oleifera oil were verified using gas chromatog.-mass spectrometry. Spectroscopic and microscopic techniques, including SEM, X-ray diffraction, and energy-dispersive X-ray anal., were employed to characterize and study the surface morphol. of the fabricated bionanocomposite film. The antimicrobial activity of the fabricated bionanocomposite film was investigated using different strains of bacteria and fungus. The results revealed well-oriented and excellently dispersed silver nanoparticles in the PVC-Moringa oleifera oil matrix. The bionanocomposite was able to inhibit the growth of Staphylococcus aureus, Escherichia coli, Klebsiella pneumoniae, Salmonella typhi, Pseudomonas aeruginosa, Shigella flexneri, and Candida albicans. The combination of nanoparticles with polymers is opening new routes for engineering fixable composites, which showed antimicrobial properties.

Chahdoura, Hassiba published the artcileBioactivity, hydrophilic, lipophilic and volatile compounds in pulps and skins of Opuntia macrorhiza and Opuntia microdasys fruits, Application of Methyl octanoate, the main research area is Opuntia hydrophilicity lipophilicity pulp skin fruit.

Opuntia genus includes several species able to grow in arid regions and known for producing delicate fruits, which are far from being thoroughly characterized. Herein, fruits from O. macrorhiza and O. microdasys were divided in skins and pulps (without including seeds) and studied for chem. composition, individual phytochems. and bioactivity. The major volatiles were camphor and Et acetate, while citric acid was the main organic acid. The fatty acids detected in highest percentages were linoleic acid (skins) and lauric acid (pulps); α-tocopherol was the major isoform of vitamin E. Quercetin-3-O-rutinoside and quercetin-O-(deoxyhexoside-rutinoside) were the main phenolics in fruit skins of O. macrorhiza and O. microdasys (resp.), similarly to piscidic acid in O. macrorhiza pulp (O. microdasys pulp showed no quantifiable compounds). Betanin and isobetanin were the major betalains. All samples were antioxidant (particularly O. macrorhiza), but antimicrobial activity was only detected in skins. Cytotoxicity was low in all cases. Overall, these fruits proved to be potential new ingredients for food or pharmaceutical related applications, adding value to these natural species able to grow in arid environments.

Mwinga, James L. published the artcileIn vitro antimicrobial effects of Hypoxis hemerocallidea against six pathogens with dermatological relevance and its phytochemical characterization and cytotoxicity evaluation, SDS of cas: 110-42-9, the main research area is Hypoxis kidney cell cytotoxicity phytochem antimicrobial; Antibacterial; Antifungal; Antioxidant; Cytotoxicity; Gas Chromatography-Mass Spectrometry (GC-MS); Hypoxis hemerocallidea; Phytochemistry; Phytocosmetics.

Hypoxis hemerocallidea (commonly known as African Potato) is popular in African traditional medicine. It is used in the management of diverse ailments including burns, wounds and skin-related diseases. The current study investigated the antimicrobial effects of Hypoxis hemerocallidea against six microorganisms associated with skin diseases. In addition, the antioxidant activity, phytochem. profiles and cytotoxicity of the bulb extracts were evaluated. The antimicrobial activity of 50% methanol (MeOH) and petroleum ether (PE) extracts of Hypoxis hemerocallidea bulbs was tested against two bacterial and four fungal strains implicated in causing opportunistic skin-related diseases. Antioxidant potential of the extract was investigated via the 2,2-diphenyl-1-picryhydrazyl (DPPH) free radical scavenging assay and β-carotene linoleic acid model. Phytochem. profiling of the 50% MeOH extract of Hypoxis hemerocallidea was done using spectrophotometric assay and Gas Chromatog.-Mass Spectrometry (GC-MS). The extracts were also evaluated for cytotoxicity against African green monkey Vero kidney cell lines based on the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) colorimetric assay. Both 50% MeOH and PE extracts showed considerable inhibitory effects against all six microorganisms. The extracts were potent against Shigella flexneri and Trichophyton tonsurans with min. inhibitory concentration (MIC) values less than 1 mg/mL. However, there was relatively poor antifungal activity against the other fungal strains. In the DPPH assay, the MeOH extract of the bulb had an EC50 of 29.8μg/mL while 76.91% antioxidant activity was observed in the β-carotene-linoleic acid model. The extract contained total phenolics (41 mg GAE/g) and flavonoids (10 mg CE/g). The GC-MS anal. of Hypoxis hemerocallidea bulb revealed 29 and 160 bioactive compounds for 50% MeOH and PE extracts, resp. Based on the cytotoxicity, Hypoxis hemerocallidea had LC50 value of 210.9 ± 18.4 and 95.5 ± 13.3μg/mL for PE and MeOH extracts, resp. The bulb extracts of Hypoxis hemerocallidea exhibited good antimicrobial and antioxidant activities, which could be attributed to the presence of phenolics, flavonoids and the other bioactive compounds identified through GC-MS, making it a potentially effective cosmetic plant. These findings also account for the multi-pharmacol. use of Hypoxis hemerocallidea in traditional medicine, especially related to skin diseases. The plant extracts can be considered as safe based on their LC50 values (< 20μg/mL). However, other form of cytotoxicity studies need to be carried out on Hypoxis hemerocallidea, as well as in vivo tests, to confirm its safety and efficacy as a treatment for skin-related diseases.

Soraggi Battagin, Tiago published the artcileSyzygium aromaticum (clove) essential oil: An alternative for the sanitization of citrus fruit in packinghouses, Product Details of C23H46O2, the main research area is Syzygium aromaticum essential oil citrus fruit packing sanitization.

Citrus canker is a quarentenary disease caused by Xanthomonas citri subsp. citri (X. citri). Thus, sanitization of fresh fruit is a necessary measure before any com. activity. Therefore, we evaluated the clove essential oil (CEO), as an alternative sanitizer for the disinfection of citrus fruit in packinghouses. Tests in vitro and in vivo were carried out to determine the cell inhibitory concentration and to verify the efficacy of the oil for the disinfection of citrus fruits. In in vitro tests, CEO was able to inhibit X. citri when used at 0.75% (volume/volume). In experiments that simulate the sanitization process used in packinghouses, 5% CEO was as effective as the recommended sanitization product based on sodium hypochlorite. GC-MS results showed a high presence of eugenol derivatives as the major compounds of CEO. All results proved that CEO is a potential sanitizer that could be used as an alternative to sodium hypochlorite. Novelty impact statement : Exptl. evidence shows that the clove essential oil (CEO) has the same sanitization efficacy as sodium hypochlorite, which makes of CEO an alternative sanitizer for the decontamination of citrus fruits to be exported to the European Union. CEO is a safer and more sustainable sanitizer for the postharvest disinfection of citrus fruit.
