Background: Vernonia amygdalina origins of Africa. Today, it is widely grown in Vietnam. Vernonia amygdalina is used by people for antibacterial purposes, hypoglycemic, protecting the liver, etc. However, there is not much research data on the trunk of this tree. Objectives: Analysis of chemical composition and antibacterial effects of the trunk Vernonia amygdalina. Materials and methods: The trunk of Vernonia amygdalina was collected in Binh Thuy district, Can Tho City. Chemical composition analysis was conducted based on the improved Ciuley method. Moreover, the antibacterial activity was investigated by using the agar diffusion method. Results: The trunk of Vernonia amygdalina contains carotenoids, coumarins, triterpenoids, saponins, flavonoids, etc. Additionally, extracts from the trunk of Vernonia amygdalina have antibacterial properties against Staphylococcus aureus, Pseudomonas aeruginosa, and E. coli bacteria with an aseptic ring sizes of 7.33 mm, 2 mm, and 4.67 mm respectively at the concentration of 200 mg/mL. Conclusions: Vernonia amygdalina of trunk was collected in Can Tho City which contained various compounds including carotenoids, coumarins, triterpenoids, saponins, flavonoids, etc. Notably, 70% alcohol extract of vernonia amygdalina trunk has the highest antibacterial activity against Staphylococcus aureus, Pseudomonas aeruginosa, and E. coli at a concentration of 200 mg/mL.
