Antioxidant Power

This study aimed to evaluate the antioxidant activity of various plant extracts. A total of 94 kinds of edible plant extracts obtained from the Korea Plant Extract Bank were screened for cytotoxicity, following which the total phenolic content of 24 shortlisted extracts was determined. Of these, extracts from three plants, namely, Castanea crenata (CC) leaf, Camellia japonica (CJ) fruit, and Viburnum dilatatum (VD) leaf, were examined for antioxidant capabilities by measuring radical scavenging activity, ferric reducing/antioxidant power, and lipid peroxidation inhibitory activity. In addition, cellular antioxidant activities of the three extracts were assessed by a cell-based dichlorofluorescein assay and antioxidant response element (ARE) reporter activity assay. The results demonstrated that all three extracts concentration-dependently scavenged free radicals, inhibited lipid peroxidation, reduced the cellular level of reactive oxygen species, and increased ARE-luciferase activity, indicating antioxidant enzyme-inducing potential. In particular, CJ extract showed significantly greater antioxidative activity and antimigratory effect in a breast cancer cell line compared to CC and VD extracts. Hence, CJ extract deserves further study for its in vivo functionality or biologically active constituents.

Streptococcus mutans strains were found to have a substantial role in the development of caries. The objective of this study is to evaluate the potential antibacterial activity of some edible plant extracts against Streptococcus mutans isolates. Fifty oral dental plaque specimens were obtained from various dental clinics in Jeddah city from 23 males and 27 females with median ages ranging between 19.9 to 51.25 years. All isolates were subjected to microbiological, biochemical, and molecular identification. The results showed that 36.3% of the bacterial isolates were identified as Streptococcus mutans, 4.5% as Streptococcus gallolyticus, and 4.5% as Staphylococcus aureus followed by two Yeast species Candida albicans (45.4%) and Candida glabrata (9.0%). The PCR products of the size of 600 and 517 bp DNA fragments were successfully amplified from 16S rRNA and glucosyltransferase gene (gtfb) from the S. mutans isolates and reference strain ATCC25175. The gtfb sequences were submitted to NCBI and assigned accessions MW491783, MW491784, MW491785, and MW491786. Six plant extracts (Guava leaves, Olive Leaves, Clove, Garlic, Green Ginger, and Cinnamon), Nanosilver 12 nm, and commercial kinds of toothpaste: 15% Sensodyne multi-care and 15% Aloe fresh – menta crystal were evaluated against the S. mutans isolates by agar well diffusion test. Most plant extracts tested exhibited considerable inhibitory effects when coupled with Nanosilver 12 nm (1:1). Clove/SNP; 106.8±4.95, and Garlic/SNP; 105.3±3.2) had the greatest mean values of MIC, whereas (Olive/SNP) exhibited the lowest (56.5±3.89). In conclusion, although there are lot of studies on edible plant extracts, incorporating nanoparticles can synergistically increase its antibacterial effectiveness.

To date, only a handful of pesticides have been authorized by the European Council for the protection of stored grains. Resistance issues and ecotoxicity concerns necessitate the development of ecofriendly tools in that direction. In this review, we refer to the recent findings on plant extracts and pure plant-derived substances with promising biological activity and the potential to be used as biopesticides for stored products. The main aim of biopesticides is to be effective against target pests, without harming humans and the environment. Many plant species, among those reported herein, are part of the human diet, and are thus not harmful to humans. Edible plant extracts produced with inorganic solvents represent safe candidates for use as repellants, fumigants or contact pesticides. Cinnamon, rosemary, parsley, garlic, oregano and basil are found in products destined for human consumption but also display significant biological activities. Interestingly, cinnamon is one of the most widely tested botanical matrixes, exhibiting the best lethal effects on almost all insect and mite taxa reported herein (Acaroidea, Coleoptera and Lepidoptera), followed by basil and garlic. Prunus persica,Azadirachta indica A. Juss and Carum sp. seem to be very promising too as miticides and/or insecticides, with A. indica already being represented commercially by a plant-derived acaricidal formulation.
