“…The parsley essential oil in our study showed high bactericidal activity mostly against P. aeruginosa, S. enterica, and S. aureus. These bacteria are common food pathogens and produce a wide variety of toxins (Al-Qurainy et al, 2013). S. aureus -for instance -is heat resistant, can live at low pH with activity in the digestive tract after ingestion, and is a common cause of skin infection and food poisoning (Evenson et al, 1988;AlQurainy et al, 2013).…”

“…In our study, the antibacterial activity of parsley essential oil -a plant that is widely used as fresh green sprigs to garnish and aromatize foods -could be an alternative to control bacteria during food processing, storage, and/or packing. Moreover, according to Al-Qurainy et al (2013), the use of crude plant extracts and essential oils can be used to reduce the use of synthetic chemical compounds in the preservation of foodstuff. Synthetic food preservatives are effective and inexpensive, but they can be also toxic for animals, the environment, and increase microorganism resistance (Aarestrup, 2000).…”

ABSTRACT. Parsley [Petroselinum crispum (Mill.) Fuss] is regarded as an aromatic, culinary, and medicinal plant and is used in the cosmetic, food, and pharmaceutical industries. However, few studies with conflicting results have been conducted on the antimicrobial activity of parsley essential oil. In addition, there have been no reports of essential oil obtained from parsley aerial parts, except seeds, as an alternative natural antimicrobial agent. Also, microorganism resistance is still a challenge for health and food production. Based on the demand for natural products to control microorganisms, and the reevaluation of potential medicinal plants for controlling diseases, the objective of this study was to determine the chemical composition and antibacterial and antifungal activities of parsley essential oil against foodborne diseases and opportunistic pathogens. Seven bacteria and eight fungi were tested. The essential oil major compounds were apiol, myristicin, and b-phellandrene. Parsley essential oil had bacteriostatic activity against all tested bacteria, mainly Staphylococcus aureus, Listeria monocytogenes, and Salmonella enterica, at similar or lower concentrations than at least one of the controls, and bactericidal activity against all tested bacteria, mainly S. aureus, at similar or lower concentrations than at least one of the controls. This essential oil also had fungistatic activity against all tested fungi, mainly, Penicillium ochrochloron and Trichoderma viride, at lower concentrations than the ketoconazole control and fungicidal activity against all tested fungi at higher concentrations than the controls. Parsley is used in cooking and medicine, and its essential oil is an effective antimicrobial agent.

“…2,3 The high cost of modern medicine and resistance of most organisms to these drugs are on the increase, and this has led to the high interest in medicinal plants. 4 Traditional medicine or ethnobotany is believed to be cheap and can provide novel drug scaffolds for drug discovery. [5][6][7] Breonadia salicina (Rubiaceace) is a monotypic genus of flowering plants.…”

Breonadia salicina is an ethnomedicinal plant used in North Central Nigeria to treat sleeping sickness and respiratory diseases. The stem bark of the plant was extracted with methanol and the extract partitioned between dichloromethane and water. The dichloromethane soluble portion was subjected to column chromatography which resulted in the isolation of 7-(β-Dapiofuranosyl (1-6)-β-D-glucopyranosyl) umbelliferone, α-amyrin, stigmasterol, 7hydroxycoumarin and 6-hydroxy-7-methoxy coumarin. The structures of these compounds were elucidated based on NMR spectral analysis. This is the first report of these compounds from the plant.

“…Many plant families are of current interest in medicinal research. Interestingly, various parts of the plants in the genus Rubiaceae have been reported to have significant antibacterial efficacies [4,5]. For instance, the roots of Catunaregam tomentosa reportedly have antibacterial properties against some Gram positive bacteria [6].…”

Purpose: To investigate the antibacterial activity of extracts from Catunaregam tomentosa on Bacillus subtilis and Staphylococcus aureus, and the bacterial responses to the extracts.Methods: The antibacterial activity of fruit, leaf and stem bark extracts were evaluated against B. subtilis (ATCC6633) and S. aureus (ATCC25923). Using a disc diffusion method, extracts at concentrations ranging from 50 -1,000 µg/disc were tested. The minimum inhibitory (MIC) and minimum bactericidal concentrations (MBC) of the extracts against the test bacteria were determined. Fluorescent activated cell sorting (FACS) was used to assess the responses of both types of bacteria to the extracts. Results: The fruit and leaf extracts at 1,000 µg/disc showed optimum efficacy against B. subtilis and S. aureus with MIC of 1,000 µg/mL against both B. subtilis and S. aureus, for the fruit and the leaf extracts. With increasing doses of fruit and leaf extracts at 6 h of incubation, FACS profiles revealed that cell death for B. subtilis increased. The fruit and leaf extracts of C. tomentosa also exhibited antibacterial activity against S. aureus in a dose-and time-dependent manner. The bacteria initially lost their granularity, then lost membrane integrity, and consequently died. Conclusion: The fruit and leaf extracts of C. tomentosa exhibit significant antibacterial potential against Gram-positive bacteria by damaging bacterial granularity and membrane integrity.
