Analysis of Essential Oil of Salix babylonica Collected in Vietnam: Phytochemical Components and Antibacterial and Anticancer Activity

Abstract

This study investigated the chemical compositions and inhibitory activities of essential oils (EOs) of Salix babylonica from Vietnam. The gas chromatography–mass spectrometry (GC/MS) system was used to analyze the chemical compositions of Salix babylonica essential oils. A total of twenty-eight and thirty-one compounds were identified in essential oils of the leaves and bark, among which many chemical compositions were identified for the first time in this plant. Salix babylonica essential oils demonstrated antibacterial activities against Gram-negative strains such as Pseudomonas aeruginosa (PA) and Escherichia coli and Gram-positive strains such as Staphylococcus aureus (SA), and demonstrated anti-cancer activities against three cancer cell lines (HepG2, MCF-7 cell, and A549). The evaluation of the ability to inhibit three strains of microorganisms and inhibit the growth of three cancer cell lines was first conducted using essential oils extracted from the plant species S. babylonica collected in Asia, which will be the basis for using essential oils of this plant in medicine.
