Background and aim
Foeniculum vulgare (F. vulgare) Mill, commonly known as fennel, belongs to the Umbelliferae (Apiaceae) family, biennial or perennial herbs disseminated in Mediterranean region and central Europe. This herbal medicine (HM) is considered as a traditional HM, and its parts have been studied.
Methods
In this survey, essential oils from seeds collected from three various regions (Kerman, Golestan, and East Azerbaijan Provinces) of Iran were prepared with hydro-distillation and their components were analyzed with gas chromatography (GC) and chromatography time-of-flight mass spectrometry (GC/MS). Antimicrobial and cytotoxic activities of the essential oils were examined with disk-diffusion method on Muller–Hinton agar and Subaru-dextrose Agar, respectively. Additionally, the MTT assay was assessed on breast cancer cell line (MCF-7). The expression of apoptosis-related genes, Bax and Bcl2, was determined using quantitative real-time PCR (RT-qPCR).
Results
The major fractions of essential oils identified by GC and GC/MS included trans-anethole (78.47%, 49.64%, 78.68%), fenchone (10.5%, 8.4%, and 10.2%), and limonene (5.9%, 6.70%, and 5.6%), respectively. Fennel oil collected from three various places exerted inhibitory effects on the bacterial growth and higher cytotoxic effects on MCF-7 cancer cell line. In addition, the essential oil increased the expression of Bax, but decreased Bcl2 gene expression significantly (P < 0.001).
Conclusion
According to our findings, F. vulgare essential oil can be considered as a promising agent opening venues for novel antimicrobial and anticancer therapies. Owing to side effects and expensiveness of chemotherapy approaches, HM is a new remarkable insight for future therapies.
