CHEMICAL COMPOSITION AND BIOLOGICAL ACTIVITIES OF BASIL ESSENTIAL OIL (OCIMUM BASILICUM L.) IN THAI NGUYEN

Abstract

Basil essential oil (Ocimum basilicum L.) sampled in Huong Thuong commune Thai Nguyen city is distilled by steam attraction with reflux. The content of essential oil from basil is 0.56% (according to air-dried materials). Essential oils have a mild aroma, light yellow color, and are lighter than water. By chromatographic mass spectrometry (GC/MS), 24 components from Basil essential oil have been identified, accounting for 99.42% of the total essential oil, the main components in Basil essential oil include Estragole (89.91). %), Methyl chavicol (2.25%), 1,8-Cineole (1.69 %) and 3-Carene (0.99%). Basil essential oil has moderate ability to inhibit Escherichia coli bacteria and shows strong inhibition of DPPH free radical. The research results of basil essential oil contribute to elucidating the chemical composition and biological activities of Thai Nguyen basil essential oil, adding to the treasure trove of Vietnamese essential oils.
