The present article describes the chemical composition and biological activities of the essential oils of B. glabrifolia leaves obtained in four consecutive years (2015–2018). The essential oils contained α‐terpineol (17.9–29.7 %), α‐terpinene (12.6–17.4 %), limonene (14.9–26.8 %) and β‐pinene (2.1–16.7 %) as the most abundant volatiles. The essential oils and these volatiles showed a significant adulticide activity ( p< 0.01; LC 50 <100 μg mL −1 ) on the maize weevil ( Sitophilus zeamais ) with a 100 % mortality rate within a period of 5 h. Also, the essential oils showed a strong antibacterial activity on Enterococcus faecalis ATCC 29212 (MIC, 132.7–173.6 μg mL −1 ) and Helicobacter pylori ATCC 43504 (MIC, 74.8–199.2 μg mL −1 ). The assessment of the main volatiles revealed α‐terpineol as the principal antibacterial agent (MIC, 78.6–149.7 μg mL −1 ). Similarly, the essential oils exhibited a substantial in vitro antiproliferative activity on the human prostate cancer cell lines PC‐3 (LC 50 , 15.2–19.4 μg mL −1 ), the human ovarian carcinoma cell lines OVCAR‐3 (LC 50 , 27.3–53.7 μg mL −1 ) and the myelogenous leukemia cell lines K‐562 (LC 50 , 32.4–75.9 μg mL −1 ). α‐Terpineol (LC 50 , 32.4–75.9 μg mL −1 ) exhibited the strongest antiproliferative effect on these cancer cell lines (LC 50 , 22.4–48.1 μg mL −1 ).
