“…The improper use of chemical preservatives may cause problems such as carcinogenicity, teratogenicity, and residual toxicity [10]. In fact, natural antibacterial agents can be applied as a food preservative instead of the currently popular chemical preservatives [11,12]. Therefore, searching for safe and natural antibacterial agents in the future, including plant extracts and essential oils (EOs), is a crucial priority.…”

Antimicrobial Activity and Proposed Action Mechanism of 3-Carene against Brochothrix thermosphacta and Pseudomonas fluorescens

3-Carene is an antimicrobial monoterpene that occurs naturally in a variety of plants and has an ambiguous antibacterial mechanism against food-borne germs. The antibacterial effects and action mechanism of 3-carene against Gram-positive Brochothrix thermosphacta ACCC 03870 and Gram-negative Pseudomonas fluorescens ATCC 13525 were studied. Scanning electron microscopy (SEM) examination and leakage of alkaline phosphatase (AKP) verified that 3-carene caused more obvious damage to the morphology and wall structure of B. thermosphacta than P. fluorescens. The release of potassium ions and proteins, the reduction in membrane potential (MP), and fluorescein diacetate (FDA) staining further confirmed that the loss of the barrier function of the cell membrane and the leakage of cytoplasmic contents were due to the 3-carene treatment. Furthermore, the disorder of succinate dehydrogenase (SDH), malate dehydrogenase (MDH), pyruvate kinase (PK), and ATP content indicated that 3-carene could lead to metabolic dysfunction and inhibit energy synthesis. In addition, the results from the fluorescence analysis revealed that 3-carene could probably bind to bacterial DNA and affect the conformation and structure of genomic DNA. These results revealed that 3-carene had strong antibacterial activity against B. thermosphacta and P. fluorescens via membrane damage, bacterial metabolic perturbations, and genomic DNA structure disruption, interfering in cellular functions and even causing cell death.

“…Essential oils are currently attracting interest in the scientific community and there is much research being conducted on their pharmacological activities; they are necessary in prevention and cure of microbial diseases and oxidative stress, including inflammations, viral infections, thrombosis, cardiovascular diseases, bacterial infections, and atherosclerosis. [14][15][16][17][18] In this work, we present gas chromatography-mass spectrometry (GC-MS) investigation of the EO components from P. guajava leaves obtained from Mirpurkhas, Pakistan, and compare the composition with several previous analyses.…”

The purpose of this study was to investigate the chemical composition of the essential oil extracted from Psidium guajava leaves and to explore the medicinal value of β-caryophyllene in pharmaceutical science. The essential oils of P. guajava leaves were extracted by the hydrodistillation method, using a Clevenger-type apparatus and the chemical composition of essential oils was investigated by gas chromatography-mass spectrometry. The yield of extracted essential oils was 0.6% (w/w) dry weight. The main compounds found in the leaves were β-caryophyllene (20.34%), globulol (8.20%), trans-nerolidol (7.72%), aromadendrene (4.34%), cis-α-bisabolene (3.82%), tetracosane (3.68%), octadecane (3.66%), Z,Z,Z-1,5,9,9-tetramethyl-1,4,7cycloundecatriene (3.44%), β-bisabolene (3.41%), limonene (3.09%), octacosane (2.88%), δ-cadinene (2.52%), and 1,4-cadadiene (2.04%). The main chemical class of the essential oil was terpenoids, which represent 71.65%, followed by hydrocarbons (26.31%). A total of 50 components were identified, among these β-caryophyllene was found to be dominant, which has great medicinal value, and some other compounds were also identified for the first time in the essential oil of P. guajava leaves.

“…It is the known fact that essential oils obtained from aromatic plants are very rich in complex compounds and the biological and pharmacological properties of some of them are confirmed scientifically. Moreover, it was reported their potential applications as natural and safe food preservatives or an antibacterial agent for both pharmaceutical and pesticide industries [26,27]. According previous reports, camphor, borneol and 1,8-cineole (eucalyptol) were common compounds of the essential oils of Tanacetum species and antimicrobial potentials of these compounds were well determined [28][29][30][31].…”
