Abstract The beet armyworm (BAW), Spodoptera exigua (Lepidoptera: Noctuidae) is a highly destructive pest of vegetables and field crops. Management of beet armyworm primarily relies on synthetic pesticides, which is threatening the beneficial community and environment. Most importantly, the BAW developed resistance to synthetic pesticides with making it difficult to manage. Therefore, alternative and environment-friendly pest management tactics are urgently required. The use of pesticidal plant extracts provides an effective way for a sustainable pest management program. To evaluate the use of pesticidal plant extracts against BAW, we selected six plant species (Lantana camara, Aloe vera, Azadirachta indica, Cymbopogon citratus, Nicotiana tabacum ,… More >

Abstract Nanoparticles (NPs) have already been widely used in catalysis, antibacterial and coating fields. Compared with the traditional toxic and harmful reducing reagents, green synthesis of NPs by using plant extracts is not only environmental-friendly and cost-effective but also conducive to the multi-level and efficient utilization of wild plant resources. In this study, the aqueous extracts from Sorbus pohuashanensis (SP) and Aronia melanocarpa (AM) fruits were used as the reducing and protective reagents for synthesizing Au/AgNPs, with the characteristics of originality operation and high repeatability. The SP/AM fruit extracts functionalized Au/AgNPs were characterized by UV-vis spectroscopy (UV-vis), transmission electron microscopy (TEM),… More > Graphic Abstract

Abstract Houttuynia cordata Thunb (HCT) is a medicinal and edible herb that has beneficial effects on various diseases due to its diuretic, anti-inflammatory, anti-oxidative, anti-microbial, anti-viral, anti-cancer and anti-diabetic properties. Most reports of its anti-cancer activity were conducted in vitro, and its effects on cutaneous squamous cell carcinoma (SCC) have not been investigated yet. Using DMBA/TPA induced SCC mice model, we found that topical treatment by HCT, as well as its bioactive ingredient monomer, efficiently inhibited tumor growth. Mechanistically, tumor infiltrating CD⁴⁺ , Foxp³⁺ T regulatory cells (Tregs) were significantly reduced and CD⁸⁺ /Treg cells ratio was largely increased in tumors… More >

Abstract Phenolic compounds are related to high biological activity, avoiding oxidation in food and human systems. Nutshells are by-products derived from the pecan nut processing that contain important amounts of phenols which biological activity must be studied. This research aimed to evaluate the antioxidant (DPPH, ABTS, FRAP and hemolysis) and anti-inflammatory activities of shell extracts from pecan nuts harvested during the crop production cycle 2018 and 2019, as well as the in vitro digestibility of their phenolic compounds, including flavonoids. Results showed that extracts from the crop production cycle 2018 obtained the highest yield, while those from 2019 contained the highest… More > Graphic Abstract

Abstract Wood is mainly made up of cellulose, hemicelluloses, lignin polymers and other organic and inorganic substances, making it susceptible to deteriorate by various biological agents. Tectona grandis L.f. (Teak) is a timber species with high resistance to biological deterioration, valued for its durability, beauty, and mechanical resistance. The purpose of this work was to evaluate the antifungal activity of crude extracts from teak on various fungi that cause wood deterioration. For this, Teak heartwood was obtained, then fragmented and pulverized until obtaining a flour which was used for compounds extraction using the Soxhlet technique coupled to a rotary evaporator through… More >

Abstract The Annona genus is a member of Annonaceae, one of the largest families of plants across tropical and sub-tropical regions. This family has been used in several ethnomedicinal practices to treat a multitude of human diseases. However, the molecular mechanism underlying its effect on the lipid droplet formation and on the expression of adipogenic markers of this plant remain to be investigated. In this study, we examined whether the extracts from the aerial part of Annona montana affect in vitro differentiation of preadipocytes. For our investigations, both mouse embryo fibroblast 3T3-L1 and normal human primary subcutaneous preadipocytes were incubated with… More >

Abstract Seeds from soybean collected from different commercial markets were surveyed for seed-borne fungi. Ninetyeight fungal colonies were isolated all over three monthly isolations constituting twenty-two fungal species. The isolated fungi were belonging to the genera: Alternaria, Aspergillus, Cephalosporium, Chaetomium, Cladosporium, Colletotrichum, Curvularia, Fusarium, Macrophomina, Mucor, Penicillium, Rhizoctonia, Rhizopus, Sclerotium, Stemphylium, and Verticillium. Assay of the antifungal activity of four ethanolic extracts of clove, cinnamon, garlic, and mint was carried out against the most common fungal species (Aspergillus flavus, A. niger, Fusarium solani, F. oxysporium, and F. moniliforme), which significantly reduced the growth of tested fungi. Clove extract recorded the highest… More >

Abstract

Chemical composition of the bark extracts of Coula edulis was investigated to find potential antioxidant, anti-termite and antifungal compounds which can find useful applications in the fields of food, nutraceuticals, cosmetics or agrochemical. Phytochemical screening revealed the presence of several groups of active molecules such as alkaloids, polyphenols, flavonoids, saponins and sterols and/or terpenes in the different extracts. Total phenols, condensed tannins and flavonoids contents corroborated phytochemical screening. Gas chromatography-mass spectrometry (GC-MS) analysis revealed compounds in dichloromethane extract different from those obtained with all the other solvents. Hexadecanoic and trans-9-octadecenoic acids, as well as stigmasterol and β-sitosterol have been identified… More >
