“…At 15-day, the oil content was 0.3044% and 0.287% for shade and sun, respectively. The value of essential oil content in this study was found within the range of research findings reported by [10,[29][30][31]. The specific gravity of rue essential oil was 0.860 at 0-day and 15day shade dry, 0.853 and 0.863 for 5-day and 10-day shade dry.…”

The genus Rue (Ruta chalepensis) is an aromatic medicinal plant used in the folk as an herbal remedy medicine for the treatment of a variety of disorders in Ethiopia. Information about the effects of drying methods and storage days on essential oil physical properties is limited. The fresh leaf of rue was collected from the Wondo Genet Agriculture research center and was subjected to sun and shade drying methods and four storage days (0,5,10, and 15) days for each day's moisture content and essential oil extraction using hydro distillation. The obtained essential oils were analyzed for physical properties (specific gravity and refractive index). The highest value of moisture content in percent was recorded at 0-day storage days with the value of 73.533 and the lowest one was recorded at 15-day sundry with the value of 8.400. The highest and lowest value of essential oil content in volume by weight in percent was 0.673 and 0.174 at 0 day and 10-day sun, respectively. The highest and lowest value of essential oil content weight by weight in percent was 0.996 and 0.287 at 0 day and 15-day sun, respectively. The results showed that the rue dried under shade had a higher level of moisture content, essential oil content, volume by weight and weight by weight, specific gravity, and refractive index compared to the rue leaf dried under sun-drying methods. In the case of storage days in all parameters except refractive index and specific gravity, the rue fresh leaf (0 days) was higher in moisture content and essential oil contents compared to others storage days. This study provides evidence that drying herbs for different storage days and different drying methods affect the essential oil content and physical properties of essential oil.

“…Twenty-eight (28) components were reported with the main component being 2-Tridecanone (38.88%), 2-Nonanone (29.56%), 2-Acetoxytridecane (18.58%), 2-Pentadecanol acetate (3.42%), 2-Decanone (1.67%), and 2-Dodecanone (1.25%), while other components were detected in trace amounts of less than 1% each, and the components with lowest concentrations were Gamma-Terpinen (0.02%) and o-Cymene (0.01%). Literature surveys showed great variability which could be due to factors such as geographical location, season and environmental factors, and the method of extraction (Boughendjioua, 2019). The presence of 2-Undecanone as a dominant component in R. chalepensis leaf oil extract was also reported in Ethiopia ( 18.58%) which are detected in this study, were not identified in previous studies.…”

Ruta chalepensis L. is an aromatic plant belonging to the family Rutaceae, widely distributed in Saudi Arabia. The study focuses on the extraction by steam distillation, phytochemical analysis, GC/MS analysis and antimicrobial activity of essential oil from the leaves of the plant. The results revealed the presence of flavonoids, terpenoids, steroids, and sugars at reasonable concentrations in ethanol, chloroform, ethyl acetate, petroleum ether and n-butanol extract of R. chalepensis leaves. GC/MS analysis identified twenty-eight compounds with the major compounds being 2-Tridecanone (38.88%), 2-Nonanone (29.56%), 2-Acetoxytridecane (18.58%), while 2-Pentadecanol acetate (3.42%), 2-Decanone (1.67%) and 2-Dodecanone (1.25%) were found in small concentrations and the other compounds were found in trace amounts of less than 1% for each. The antimicrobial activity determined by the disc diffusion method showed that the highest activity was observed against Staphylococcus aureus (inhibition zone of 20.33±0.151 mm), followed by Escherichia coli (inhibition zone of 16.67±0.158 mm), Bacillus cereus and Candida albicans (inhibition zones of 15.67±0.254 mm and 15.33±2.52 mm, respectively) and the lowest activity was against Pseudomonas aeruginosa (inhibition zone of 14.67±1.64 mm). The study, therefore, highlighted on the fact that extracted essential oil could be considered as a potential antimicrobial agent in therapeutic and pharmaceutical applications.

“…Cichorium pumilum, which is widely used as a traditional medicinal herb, showed antibacterial activity in vitro with agar disc diffusion and agar well diffusion methods against 10 different bacterial species [44]. The antimicrobial activity of Ruta chalepensis L. was tested against four pathogenic bacteria-Staphylococcus aureus, Bacillus subtilis, Escherichia coli, and Pseudomonas aeruginosa-and the findings indicate possible applications for the treatment of various infectious and noninfectious diseases [45]. The antibacterial effects of essential oil of Chrysanthemum coronarium demonstrated pronounced activity against gram-positive strains of bacteria: Bacillus subtilis (19 mm), Staphylococcus aureus (20 mm), Staphylococcus epidermidis (18 mm), Escherichia coli (9 mm), and Pseudomonas aeruginosa (12 mm), which were assessed by measuring the zone of inhibition [46].…”

Correlation between Antibacterial Activity and Free-Radical Scavenging: In-Vitro Evaluation of Polar/Non-Polar Extracts from 25 Plants

et al. 2020

Objectives: The current study aimed to measure the antioxidant and antibacterial activities of 25 wild Palestinian edible plants, which were subjected to extraction by polar and non-polar solvents. Correlations between free radical scavenging activity and antibacterial activity of the extracts were assessed for both polar and non-polar fractions. Materials: Twenty-five wild edible plant species that are frequently consumed by people in Palestine (mainly in a rural area) were examined. Among them, 10 plant species were among those with the highest mean cultural importance values, according to an ethnobotanical survey that was conducted in the West Bank, Palestine, a few years ago. Method: The protocol of the DPPH assay for testing free-radical scavenging was utilized for determining EC50 values, while microdilution tests were conducted to determine the 50% inhibitory concentration (IC50) of the extracts for the microorganism Staphylococcus mutans. Results and Discussion: Eight extracts (non-polar fractions) were found to possess an antibacterial IC50 of less than 20 ppm, such as Foeniculum vulgare, Salvia palaestinafruticose, Micromeria fruticose, Trigonella foenum-graecum, Cichorium pumilum jacq, Salvia hierosolymitana boiss, Ruta chalepensis, and Chrysanthemum coronarium. The polar fractions possess higher antioxidant activity, while non-polar fraction possess higher antibacterial activity. Looking at all the results together can deceive and lead to the conclusion that there is no correlation between antibacterial activity against S. mutans and free radical scavenging (R2 equals 0.0538). However, in-depth analysis revealed that non-polar plant extracts with an EC50 of free radical scavenging ≤100 ppm have a four-fold order of enrichment toward more activity against S. mutans. These findings are of high importance for screening projects. A four-fold order of enrichment could save plenty of time and many in screening projects. The antibacterial active extracts marked by low-medium free radical scavenging might act through a mechanism of action other than that of highly active, free radical scavenging extracts. Conclusion: The screening of antioxidant and antimicrobial activity performed on 25 selected wild plant extracts revealed a satisfactory free radical scavenging and antimicrobial potential that could be of value in the management of oxidative stress. Further studies are recommended to explore novel and highly active natural antibacterial products.
