“…In the current study, petroleum ether and methanol extracts of R. chalepensis had a considerable antibacterial activity against the use of gram-positive and gram-negative bacterial species. Similarly, Amdouni et al 50 used gas chromatography to identify the chemical composition of R. chalepensis leaves, stems, and roots grown under salt stress, and the extract of these plants had antibacterial activity against eight bacteria ( Salmonella All, Salmonella K, Escherichia coli 45AG, Escherichia coli 45AI, Staphylococcus aureus 9402, Staphylococcus aureus 02B145, Listeria 477 and Pseudomonas aeruginosa ATCC 10145).…”

Background: Although traditional healers in Ethiopia have a long history of using medicinal plants to treat diseases in animals and humans, studies on the antibacterial activities and potential bioactive ingredients of most medicinal plants have been insufficient. Therefore, this study aimed to evaluate the in-vitro antibacterial activities and to screen phytochemical constituents of selected medicinal plants against reference bacterial strains. Methods: The fresh and healthy roots of Echinops amplexicaulis, fruits of Ruta chalepensis, and leaves of Salix subserrata were collected from West Shewa Zone, Ethiopia. Agar well diffusion and agar dilution methods were used to evaluate antibacterial activities and minimum inhibitory concentrations (MIC). All the crude plant extracts were tested against Staphylococcus aureus, Streptococcus pneumoniae, Escherichia coli and Pseudomonas aeruginosa at concentrations of 100, 50, and 25 mg/mL in each triplet (3x). MIC of crude extracts ranging from 1.5625 to 12.50 mg/mL was applied to all bacterial strains. The positive control was ciprofloxacin disk (5 μg) and the negative control was 5% dimethyl sulfoxide. The presence of secondary metabolites of each crude extract was screened. The group means comparisons were done using one-way ANOVA and results were presented as mean ± standard deviation. Results: Although all selected plant extracts had shown antibacterial activities, methanol extracts had a greater zone of inhibition against all reference bacterial strains when compared to petroleum ether extracts. The growth of P. aeruginosa was inhibited at a minimum concentration of both methanol and petroleum extracts (1.5625 mg/mL) when compared to the remaining bacterial strains. Phytochemical screening showed that saponins and alkaloids were found in all crude plant extracts, while phytosterol was meager. Conclusion:This study revealed that all tested plants had significant secondary metabolites and antibacterial activities against reference bacterial strains.

“…From the studies on the composition of the essential oils of Ruta species, it appears that these essential oils, unlike many other plant essential oils, generally lack terpene components, but predominantly possess aliphatic ketones and some minor aliphatic alcohols. Based on the studies conducted on the dried or fresh plant materials of Ruta species ( Table 1 ) [ 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 , 37 , 38 , 39 , 40 , 41 , 42 , 43 , 44 , 45 , 46 , 47 , 48 , 49 , 50 , 51 , 52 , 53 , 54 , 55 , 56 , 57 ,…”

“…The antibacterial activity reported for R. chalepensis essential oil was mostly associated with the essential oils obtained from its whole aerial parts and leaves ( Table 2 ). The only report on the antibacterial activity of its root essential oil was observed against Listeria monocytogenes and Pseudomonas aeruginosa [ 17 ], while that of the essential oil from its stem was tested against Escherichia coli , Listeria monocytogenes , Pseudomonas aeruginosa , Salmonella typhi , and Staphylococcus aureus [ 17 ]. This study [ 17 ] demonstrated that a significant difference could exist between the antibacterial profiles of Ruta essential oils obtained from two different organs of the same plant and that they can have different chemical properties.…”

Ruta Essential Oils: Composition and Bioactivities

Ruta L. is a typical genus of the citrus family, Rutaceae Juss. and comprises ca. 40 different species, mainly distributed in the Mediterranean region. Ruta species have long been used in traditional medicines as an abortifacient and emmenagogue and for the treatment of lung diseases and microbial infections. The genus Ruta is rich in essential oils, which predominantly contain aliphatic ketones, e.g., 2-undecanone and 2-nonanone, but lack any significant amounts of terpenes. Three Ruta species, Ruta chalepensis L., Ruta graveolens L., and Ruta montana L., have been extensively studied for the composition of their essential oils and several bioactivities, revealing their potential medicinal and agrochemical applications. This review provides a systematic evaluation and critical appraisal of publications available in the literature on the composition and bioactivities of the essential oils obtained from Ruta species and includes a brief outlook of the potential applications of nanotechnology and chitosan-based products of Ruta essential oils.

“…EOs are used in perfumery, pharmaceutical, and food (cheese flavoring) industries. The antioxidant, anti-inflammatory, anthelmintic, antiparasitic, and antimicrobial properties have been described [6]. The main essential oil (EO) compositions of R. graveolens are largely dependent on the ecotype, environment, and external elicitors (for secondary metabolites) [7,8].…”

Elevated Bioactivity of Ruta graveolens against Cancer Cells and Microbes Using Seaweeds

Human cancer and pathogenic microbes cause a significant number of deaths every year. Modulating current sources of natural products that control such diseases becomes essential. Natural algae, such as Ascophyllum nodosum and Ecklonia maxima, can modulate the metabolic processes as well the bioactivities of Ruta graveolens L. The R. graveolens plants were subjected to nine soil drenches of A. nodosum (7 mL L−1), E. maxima (7 mL L−1), or both extracts. Morphological performance, gas exchange parameters, and essential oils (EOs) composition (GC-MS) were studied and the bioactivity was assessed against several cancer cells and pathogenic bacteria or fungi. Treatment with A. nodosum + E. maxima seaweed extracts (SWE) led to the highest morphological performance and gas exchange parameters. The highest antiproliferative, apoptotic, and caspase-3/7 activities of EO were against HeLa in SWE mixture treated plants. The best EO antimicrobial activities were obtained against Staphylococcus aureus and Penicillium ochrochloron. SWE mixtures treated plants showed the best bioactivities against microbes and cancer cells. The highest abundance of 2-undecanone (62%) and 2-nonanone (18%) was found in plants treated with SWE mixtures and caused the best anticancer and antimicrobial effects. Seaweed mixtures act as natural elicitors of pharmaceutical industries and favored 2-undecanone and 2-nonanone in R. graveolens.
