Abstract

A simple, cost-effective and eco-friendly synthesis technique of silver nanoparticles (AgNPs) using the aqueous extracts of Egyptian date palm (Phoenix dactylifera L.) seeds and their antibacterial activity assessment have been conducted. Theaqueous extract was used as reducing and stabilizer agents in the synthesis of AgNPs. Characterization of AgNPs was done using different methods including ultraviolet-visible spectroscopy (UV-Vis), Fourier transform infrared (FTIR), field emission-scanning electron microscope (FE-SEM), and X-ray diffraction (XRD). UV-Vis spectrum of the aqueous medium containing AgNPs showed an absorption peak at around 432 nm. FTIR spectra had shown that the biomolecules were responsible for the reduction and capping agents of AgNPs. XRD study showed the particles to be crystalline with a face-centered cubic (fcc) structure. The AgNPs exhibited significant anti-bacterial activity against Bacillus subtilis, Escherichia coli, Enterococcus faecalis, and Staphylococcus aureus. Overall, these findings suggest that biosynthesized AgNPs may be used as a potential therapeutic formulation against bacterial infections.

Abstract

Palladium ion (Pd(II)) is one of the hazardous metal pollutants commonly found in industrial effluents and poses severe environmental and human health impacts. The present study has chosen the leaves of Moringa oleifera (L-MO) as a potential biosorbent for removing Pd(II) from the aqueous solution. Various parameters such as pH, biosorbent dose, and initial Pd(II) concentration were optimized for maximum removal of Pd(II) using standard protocols. The Fourier-transform infrared spectroscopy study was performed to identify the functional groups involved in Pd(II) biosorption mechanism. The analysis of FTIR spectra confirmed the involvement of functional groups such as C–O, C=O, C–H, and O–H in the biosorption of Pd(II) on the surface of L-MO. The biosorption of Pd(II) was highest at pH 6. The sorption equilibrium data were well-fitted with the Langmuir isotherm model (R2 = 0.9896). The highest adsorption capacity of L-MO was 41.15 mg/g. It is concluded that the L-MO could be used as a potentially low-cost novel biosorbent to remove Pd(II) from contaminated water.

Abstract

Escherichia coli is a type of Gram-negative bacteria that is commonly found in the human digestive tract. It has been reported as one of the bacteria that has been resistant to several antibiotics. This study aims to determine four (4) types of weed extracts that are considered but have not been used as antibacterial compounds against E. coli. This experimental study used a completely randomized design with several types of plant extracts, namely Acalypha indica L., Ageratum conyzoides, Phyllanthus niruri L., and Amaranthus spinosios at various concentrations (0, 50, and 100%). The results showed that the plant extract of A. indica L. had the ability as an antibacterial against the growth of E. coli at concentrations of 50% (1.41 ± 0.12) and 100% (1.53 ± 0.01) compared to other extracts. Meanwhile, the lowest average diameter of the inhibition zone for E. coli bacteria was found in the treatment of A. spinosios grass leaf extract 50% (1.17 ± 0.05).

Abstract

In this study, we conducted a comparative investigation into the phytochemical screening and antioxidant activity of aqueous extracts from various parts of the Bauhinia purpurea plant, including leaf, flower, stem bark, and root. The qualitative analysis was performed to screen the phytochemical content of each extract, followed by quantitative analysis to determine the total phenolic and total flavonoid contents. Our findings revealed that different parts of the B. purpureaplant yielded distinct natural products upon extraction. Both the leaf and flower extracts contained alkaloids, flavonoids, saponins, carbohydrates, polyphenols, and phenolics. On the other hand, the aqueous extracts of the stem barks and rootparts of B. purpurea only contained alkaloids, flavonoids, and phenolics. Consistent with the phytochemical assay, the flower extract exhibited the highest total phenolic content (40.14 ± 0.65 µg/mL GAE) and the highest flavonoid content (387.57 ± 0.63 µg/mL CE) compared to the other parts. Consequently, the flower extract displayed the highest antioxidant activity (51.76 ± 0.32%) with DPPH radical assay, closely approaching the antioxidant activity of ascorbic acid (70.54 ± 0.51%), which served as the positive control. This significant finding highlights the potential of the B. purpurea flower as a potent source of antioxidant agents for future applications.

Abstract

The content of betel leaf (Piper betle) includes essential oils, alkaloids, flavonoids, phenols, and steroids. Flavonoid compounds in P. betle show a mechanism of action in damaging bacterial cell proteins and disrupting irreparable membranes. On the other hand, mint leaves (Mentha piperita) contain essential oil ranging from 1-2%, with menthol content around 80-90%, as well as mentone, d-piperitone, hexanol phenyl acetate, ethyl amyl carbinol, and neomenthol. The aim of this study is to determine the effectiveness of the combination of P. betle extract and M. piperita extract in inhibiting the growth of Streptococcus mutans (S. mutans) bacteria using the well diffusion method. Extraction of P. betle and M. piperita extracts were performed using the maceration method. The extraction results showed a yield of 24.94% for the P. betle extract and 35.39% for the M. piperita extract. The antibacterial testing against S. mutans showed an inhibition zone of 21.83 ± 1.58 mm for the single P. betle extract (ML), 11.2 ± 1.00 mm for the M. piperita (GBL), and 11.76 ± 0.57 mm for the combination extract (GBL/ML). There is an influence of the combination of P. betle and M. piperita extracts on the antibacterial effectiveness against S. mutans, although the inhibition zone of the P. betle is larger, measuring 21.83 ± 1.58 mm.

Abstract

In the context of the steadily increasing prevalence of malignant disorders all over the world, identification of any novel possibilities for suppressing carcinogenesis is crucial leading to saving human lives. One of the important sources of exposure to potential carcinogens is food products which can be contaminated with different types of mycotoxins. These structurally diverse chemicals are produced by certain fungi, whereas many of them may be associated with the development of malignant neoplasms in distinct organ systems. In this perspective article, the ability of specific plant secondary metabolites from the class of flavonoids to suppress the release of carcinogenic mycotoxins from certain fungi, mostly the members of Aspergillus and Penicillium genera, is highlighted. This finding might support the development of novel flavonoid-based plant fungicides in the future, to lower the contamination of food products with mycotoxins and thereby also reduce the cancer prevalence in humans. In addition, the application of flavonoids as natural products instead of synthetic chemicals in plant cultivation is probably also more acceptable for final consumers, representing an actual step toward a greener future.

Abstract

Nature serves as an excellent inspiration for researchers in the fields of chemistry and medicine. Terrestrial or marine organisms produce billions of natural products with unique chemical and physical properties. Some of them have been used in traditional therapy for specific diseases since ancient times. Although their exact chemical structures have yet to be elucidated clearly in that time, investigations in medicinal chemistry have been well documented. Furthermore, utilizing natural products in drug design and development offers advantages such as high biocompatibility, low toxicity, fewer side effects, wide bioactivities, and large structure diversity. Nowadays, rational drug research using computer-aided drug design is well established to cut the long way of drug discovery and overcome the resistance cases and the increment in the number of active patients. This review will highlight some natural products to comprehensively understand their journey from unknown natural products, isolation, purification, characterization, in silico evaluation, bioactivity screening assay, drug modifications, in vitro investigation, in vivo examination, and clinical trial.

Abstract

New and improved skin care products and procedures have been established by technological advances and scientific investigation. By increasing the skin's moisture, firmness, and elasticity, anti-aging skin care can enhance the skin's overall condition. The objective of this study was to examine the potential of basil's chemical compounds as an in silicoanti-aging agent. Exploration of online databases, scholarly articles from national and international journals, and analysis using docking software are selected as examples of data collection methods. Matrix metalloproteinase 1 (MMP1), with PDB code 966C, is one of the targeted proteins related to skin anti-aging. Ladanein, acacetin, luteolin, 5-hydroxy-7,4'-dimethoxyflavone and genkwanin are five basil compounds that are predicted to exhibit anti-aging agents based on the presence of the binding affinity score indicator and the similarity of the appropriate attachment sites compared to the native ligand used. The scores for the binding affinity of luteolin, ladanein, acacetin, 5-hydroxy-7,4'-dimethoxyflavone, and genkwanin are -10, -9.9, -9.9, -9.8, and -9.6 kcal/mol, respectively. At the attachment positions of five basil compounds, the interactions with ASN 180, LEU 181 and ALA 182 key amino acids, which are the attachment sites for the native ligands, were also formed.

Abstract

Various agricultural products are known to have anti-microbial, anti-cancer, and anti-inflammatory effects. As we can mention, Walnut (Juglans regia) husk, orange (Citrus sinensis) peel, Broad bean (Vicia faba) peel, and Nettle (Urtica urens) are proven to have antimicrobial and anticancer actions. Also, plant diseases such a Pectobacterium carotovorum, Ralstonia solanacearum, Dickeya chrysanthemi, and Pseudomonoas syringae are known to cause annual damage to plant products. Therefore, in the current study, the researchers evaluated their antibacterial activity on the mentioned bacteria under in vitro conditions. Extracts of J. regia husk, C. sinensis peel, V. faba outer peel and U. urens were prepared by maceration method and their anti-bacterial activity on P. carotovorum, D. chrysanthemi, P. syringae, R. solancearum was evaluated using blank disk and well diffusion to obtain minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) values. J. regia (husk) and V. faba (outer peel) extracts revealed an anti-bacterial effect on all 4 studied bacteria, while C. sinensis (peel) only inhibited the growth of P. syringae and U. urens only had this effect on P. syringae and R. Solancearum. The inhibition zones varied from 8 to 14 mm, while almost all MIC and MBC rates were 6.25 and 12.5 mg/mL, respectively. Based on the antimicrobial results, the extracts that showed suitable antibacterial effects on certain bacteria can be further studied to be used as natural pesticides.

Abstract

Hornstedtia alliacea has been traditionally used by indigenous people for a variety of medicinal purposes. This study aimed to determine the antibacterial activity of ethanol extracts of Galoba seeds (Hornstedtia alliacea) against standard bacterial cultures of Staphylococcus aureus (ATCC-29213) and Escherichia coli (FNCC-6183) using Kirby-Bauer disk diffusion method. The phytochemical tests were carried out to determine the presence of active substances which are antibacterial in the results of the extraction. The color intensity or the precipitate formation was used as analytical response to these tests. The major phytochemical constituents identified in galoba seeds ethanol extracts were tannins, flavonoids, saponins, quinones, and steroids. The antibacterial assay showed that galoba seed extract inhibited the growth of S. aureus and E. coli. The diameter of the inhibition zone increased as the extract concentration increased. The largest inhibition zone for S. aureus was at a concentration of 100% with a diameter of 20.93 mm and the largest inhibition zone for E. coli was at a concentration of 100% with a diameter of 18.05 mm. The results of this study indicated that the plant contains some major bioactive compounds that inhibit the growth of microorganisms, thereby showing great potency as an effective source of drugs. The phytochemical analysis also reveals that the plant contains similar constituents useful for medicinal purposes.
