Background: Breast cancer is one of the most common cancers in women. Current treatments, such as chemotherapy and radiation therapy, often involve numerous side effects. Consequently, it is essential to discover new anticancer compounds that are safer and more effective. Objectives: The aim of this research is to investigate the anticancer effects of Hymenocrater longiflorus Benth. essential oil. Methods: The anticancer properties of H. longiflorus Benth. essential oil were investigated on MDA-MB-231 and MCF-7 breast cancer cells using MTT assay, double staining with acridine orange/ethidium bromide, and flow cytometry. The essential oil of H. longiflorus Benth. was analyzed using gas chromatography-mass spectrometry (GC-MS). Results: The essential oil significantly reduced the viability of breast cancer cells depending on the concentration (dose) and duration. Results from double fluorescent staining and flow cytometric analysis also indicated that apoptosis is the primary mechanism of cell death. Non-targeted GC-MS metabolomic data analysis of the essential oil revealed the presence of various anticancer compounds, including α-pinene, linalool, and caryophyllene, in the essential oil. Conclusions: In conclusion, the essential oil of H. longiflorus Benth. is a promising source of anticancer metabolites that can be further evaluated for drug therapy or as a co-treatment with conventional chemotherapeutic agents.
