BACKGROUND AND STUDY AIM: Peptic ulcer is one of the most serious diseases in Egypt, affecting more than one-third of the population. Helicobacter pylori is the main organism responsible for peptic ulcer formation. These ulcers can lead to chronic active gastritis and lymphoma. As such, in this study, we evaluate the efficacy of Pelargonium graveolens oil for the treatment of H pylori, as well as its synergistic effects with the antibiotic clarithromycin (CLR).
PATIENTS AND METHODS: We evaluated the chemical composition of P. graveolens volatile oil as well as its anti-Helicobacter activities. We assessed the volatile oil components using gas chromatography coupled with mass spectrometry. We determined anti-H. pylori potential using a micro-well dilution method.
RESULTS: We identified 92 compounds from the oil. Citronellol, geraniol, citronellyl formate, and isolongifolan-7-α-ol were the predominant components (15.64%, 11.31%, 10.19%, and 7.84%, respectively). The oil exhibited a good activity against H. pylori at an minimal inhibitory concentration of 15.63 µg/ml. Once we combined the volatile oil with CLR, a significant synergistic effect appeared at an fractional inhibitory concentration index of 0.38 µg/ml.
CONCLUSION: The in-vitro interaction between the P. graveolens oil and CLR improved the antimicrobial activity of the latter, suggesting that further studies are needed to determine formulations for potential antimicrobial applications in food and pharmaceuticals.
