Allium tuberosum is commonly grown in many provinces of Vietnam. It was considered as a folk medicine to treat many diseases. In this study, qualitative analysis and biological activities of the aerial parts of Allium tuberosum were investigated. The aerial parts of Allium tuberosum were collected in Hue city. Determination of chemical composition in the extract was carried out by chemical reactions. Essential oil was extracted by steam distillation. The antimicrobial activies were carried out by the concentration dilution method. The result showed that Allium tuberosum aerial parts’s extract contains flavonoids, tannins, alkaloids, saponins, organic acids and sugars. Essential oil of Allium tuberosum’s aerial parts has 52 components of which the main component is phytol (24.86%). The n-hexan fraction is resistant to L.fermentum. The dichloromethane fraction is resistant to B.subtilis, L.fermentum. Ethyl acetate fraction is resistant to B.subtilis. The aerial part’ essential oil is resistant to B.subtilis, L.fermentum and C.albican. The chemical composition of Allium tuberosum aerial parts’s extract and A.tuberosum aerial parts essential oil have been quantified, and their antimicrobial activities have been determined.Hẹ được trồng phổ biến ở nhiều tỉnh thuộc nước ta và được dùng để chữa nhiều bệnh theo kinh nghiệm dân gian.
