TL;DR: Three essential oils from three samples: fresh, air-dried and processed flowers of Chrysanthemum indicum, obtained by hydrodistillation, were analyzed by GC-MS and showed that both essential oils possessed significant antimicrobial effect, however, some difference in antimicrobial activity between two oils was observed.
TL;DR: In this study the composition and antimicrobial properties of essential oils obtained fromOriganum onites, Mentha piperita, Juniperus exalsa, Chrysanthemum indicum, Lavandula hybrida, Rosa damascena, Echinophora tenuifolia, Foeniculum vulgare were examined and some components with antimicrobial activity were found.
Abstract: In this study the composition and antimicrobial properties of essential oils obtained fromOriganum onites, Mentha piperita, Juniperus exalsa, Chrysanthemum indicum, Lavandula hybrida, Rosa damascena, Echinophora tenuifolia, Foeniculum vulgare were examined. To evaluate thein vitro antibacterial activities of these eight aromatic extracts; theirin vitro antimicrobial activities were determined by disk diffusion testing, according to the NCCLS criteria.Escherichia coli (ATTC 25922J,Staphylococcus aureus (ATCC 25923) andPseudomonas aeruginosa (ATTC 27853 were used as standard test bacterial strains.Origanum onites recorded antimicrobial activity against all test bacteria, and was strongest againstStaphylococcus aureus. ForRosa damascena, Mentha piperita andLavandula hybrida antimicrobial activity was recorded only toStaphylococcus aureus. Juniperus exalsa, and Chrysanthemum indicum exhibited antibacterial activities against bothStaphylococcus aureus andEscherichia coli. We also examined thein vitro antimicrobial activities of some components of the essential oils and found some components with antimicrobial activity.
TL;DR: The present work reports a simple, cost-effective, and ecofriendly method for the synthesis of silver nanoparticles (AgNPs) using Chrysanthemum indicum and its antibacterial and cytotoxic effects, which revealed a significant effect against the bacteria Klebsiella pneumonia and Escherichia coli.
Abstract: The present work reports a simple, cost-effective, and ecofriendly method for the synthesis of silver nanoparticles (AgNPs) using Chrysanthemum indicum and its antibacterial and cytotoxic effects. The formation of AgNPs was confirmed by color change, and it was further characterized by ultraviolet-visible spectroscopy (435 nm). The phytochemical screening of C. indicum revealed the presence of flavonoids, terpenoids, and glycosides, suggesting that these compounds act as reducing and stabilizing agents. The crystalline nature of the synthesized particles was confirmed by X-ray diffraction, as they exhibited face-centered cubic symmetry. The size and morphology of the particles were characterized by transmission electron microscopy, which showed spherical shapes and sizes that ranged between 37.71-71.99 nm. Energy-dispersive X-ray spectroscopy documented the presence of silver. The antimicrobial effect of the synthesized AgNPs revealed a significant effect against the bacteria Klebsiella pneumonia, Escherichia coli, and Pseudomonas aeruginosa. Additionally, cytotoxic assays showed no toxicity of AgNPs toward 3T3 mouse embryo fibroblast cells (25 μg/mL); hence, these particles were safe to use.
TL;DR: Results reveal that CIBF possesses anti-inflammatory, humoral and cellular immunomodulatory and mononuclear phagocytic activities, probably due to the presence of flavonoids.
TL;DR: Five plant-based foods investigated for intestinal α-glucosidase and pancreatic α-amylase inhibitory activities and their additive and synergistic interactions were evaluated, showing additive interaction on intestinal maltase inhibition and the combination of chrysanthemum, mulberry, or bael extracts together with roselle extract produced synergistic inhibition.
Abstract: Plant-based foods have been used in traditional health systems to treat diabetes mellitus. The successful prevention of the onset of diabetes consists in controlling postprandial hyperglycemia by the inhibition of α-glucosidase and pancreatic α-amylase activities, resulting in aggressive delay of carbohydrate digestion to absorbable monosaccharide. In this study, five plant-based foods were investigated for intestinal α-glucosidase and pancreatic α-amylase. The combined inhibitory effects of plant-based foods were also evaluated. Preliminary phytochemical analysis of plant-based foods was performed in order to determine the total phenolic and flavonoid content. The dried plants of Hibiscus sabdariffa (Roselle), Chrysanthemum indicum (chrysanthemum), Morus alba (mulberry), Aegle marmelos (bael), and Clitoria ternatea (butterfly pea) were extracted with distilled water and dried using spray drying process. The dried extracts were determined for the total phenolic and flavonoid content by using Folin-Ciocateu’s reagent and AlCl3 assay, respectively. The dried extract of plant-based food was further quantified with respect to intestinal α-glucosidase (maltase and sucrase) inhibition and pancreatic α-amylase inhibition by glucose oxidase method and dinitrosalicylic (DNS) reagent, respectively. The phytochemical analysis revealed that the total phenolic content of the dried extracts were in the range of 230.3-460.0 mg gallic acid equivalent/g dried extract. The dried extracts contained flavonoid in the range of 50.3-114.8 mg quercetin equivalent/g dried extract. It was noted that the IC50 values of chrysanthemum, mulberry and butterfly pea extracts were 4.24±0.12 mg/ml, 0.59±0.06 mg/ml, and 3.15±0.19 mg/ml, respectively. In addition, the IC50 values of chrysanthemum, mulberry and butterfly pea extracts against intestinal sucrase were 3.85±0.41 mg/ml, 0.94±0.11 mg/ml, and 4.41±0.15 mg/ml, respectively. Furthermore, the IC50 values of roselle and butterfly pea extracts against pancreatic α-amylase occurred at concentration of 3.52±0.15 mg/ml and 4.05±0.32 mg/ml, respectively. Combining roselle, chrysanthemum, and butterfly pea extracts with mulberry extract showed additive interaction on intestinal maltase inhibition. The results also demonstrated that the combination of chrysanthemum, mulberry, or bael extracts together with roselle extract produced synergistic inhibition, whereas roselle extract showed additive inhibition when combined with butterfly pea extract against pancreatic α-amylase. The present study presents data from five plant-based foods evaluating the intestinal α-glucosidase and pancreatic α-amylase inhibitory activities and their additive and synergistic interactions. These results could be useful for developing functional foods by combination of plant-based foods for treatment and prevention of diabetes mellitus.
