Abstract
Introduction
Bacterial food-borne diseases have been a major public health issue worldwide for decades. Oenanthe javanica (Blume) DC. is a small perennial herb of family Apiaceae, commonly found in Asia. The present study aims to evaluate the antibacterial, antioxidant, and cytotoxic capabilities, as well as the antibacterial mechanism of action, of Oenanthe javanica essential oil (OJEO).
Methods
In-vitro antibacterial activity was evaluated by Disc diffusion and microbroth dilution methods against Salmonella enterica serovar Typhimurium (ATCC 14028). Flow cytometric analysis was done to assess the effects of oil on membrane integrity and membrane potential. Electron Microscopy (SEM and TEM) was done to investigate morphological and intracellular damages initiated by the oil. Phytochemical profiling of oil was done by Gas Chromatography Mass - Spectrometry (GC-MS). Anti-proliferative property of OJEO was measured against 5 proliferative cell lines by MTT and NRU assay.
Results
OJEO exhibited encouraging antibacterial activity against Salmonella enterica serovar Typhimurium (ATCC 14028); MIC and MBC values were 1000 μg/mL and 1500 μg/mL, respectively. Oil treatment compromised bacterial membrane integrity and led to a decreased bacterial membrane potential. (SEM) and (TEM) analyses confirmed oil induced morphological and intracellular damage. Phytochemical characterization affirmed 47 components with β-pinene (11.29 %), γ-terpinene (32.55%), p-cymene (20.83%), α-terpinolene (7.42 %), myrcene (2.09 %) as major chemical constituents. Oil had moderate antiproliferative activity against A549, MCF-7, HaCat, HCT116 and HepG2 cell lines.
Conclusion
This study illustrates the significant antimicrobial, antioxidant, and cytotoxic properties of OJEO, indicating its potential as a therapeutic agent for bacterial diseases. Food systems and associated industries may utilise OJEO as a natural solution for combating food-borne bacteria and as a preservative agent.
期刊介绍:
The Journal of Herbal Medicine, the official journal of the National Institute of Medical Herbalists, is a peer reviewed journal which aims to serve its readers as an authoritative resource on the profession and practice of herbal medicine. The content areas of the journal reflect the interests of Medical Herbalists and other health professionals interested in the clinical and professional application of botanical medicines. The objective is to strengthen the research and educational base of herbal medicine with research papers in the form of case studies, original research articles and reviews, monographs, clinical trials and relevant in vitro studies. It also publishes policy statements, opinion pieces, book reviews, conference proceedings and profession related information such as pharmacovigilance reports providing an information source for not only the Herbal Practitioner but any Health professional with an interest in phytotherapy.
