ABSTRACT

Chamomile essential oil (CEO) is extracted from chamomile and mainly used in aromatherapy. The chemical constituents and its antitumor activity on Triple-negative breast cancer (TNBC) was explored in the present study. Gas chromatography-mass spectrometry (GC/MS) was employed to analyze the chemical constituents of CEO. The cell viability, migration and invasion of TNBC cell MDA-MB-231 were measured using MTT, wound scratch and Transwell assay, respectively. The protein expression of PI3K/Akt/mTOR signaling pathway was determined by Western blot. CEO is rich in terpenoids (63.51 %), among which the identified terpenoids and their derivatives are mainly Caryophyllene (29.57 %), d-Cadinene (12.81 %), Caryophyllene oxide (14.51 %), etc. Three concentration of CEO (1, 1.5, 2 μg/mL) significantly inhibited the proliferation, migration and invasion of MDA-MB-231 cells with a dose dependent manner. Moreover, the phosphorylation of PI3K, Akt and mTOR was inhibited by CEO. The results revealed that there was abundant terpenoids in the CEO which account for 63.51 %. CEO significantly inhibited the proliferation, migration and invasion of MDA-MB-231 cells, exhibiting antitumor effect on TNBC. The antitumor effect of CEO might attribute to its inhibition on PI3K/Akt/mTOR signaling pathway. However, further study should be conducted in more TNBC cell lines and animal models to provide further evidence for TNBC treatment by CEO.
