Essential oils with anti-breast cancer activities from Aralia chinensis L. (roots, stems, and leaves) via gas chromatography-mass spectrometry analyses and molecular docking.

Aralia chinensis L. is a traditional Miao ethnic medicine known for its pain and inflammation relief and its ability to dispel wind and dampness. This study aimed to assess its antitumour activity and identify the chemical constituents of A. chinensis essential oils. Gas chromatography-mass spectrometry was used to analyse the volatile oil composition, which identified 35, 35, and 24 constituents in essential oils from roots, stems, and leaves, respectively. Network pharmacology predicted the possible key targets of common components in breast-cancer treatment, which revealed AKT1, SRC, EGFR, STAT3, and MAPK3 as high-priority targets with high active-constituent affinity. CCK-8 assay confirmed the inhibitory effect of the essential oils on MCF-7 breast-cancer cells, with oils from Aralia rhizomes, stems, and leaves inhibiting cell viability by 77%, 64%, and 62%, respectively. The active components of Aralia essential oils show promise for breast-cancer treatment by targeting AKT1, SRC, EGFR, and other key factors.
