This work aimed to identify the bioactive constituents and antibacterial activity of a cold methanolic extract of Olea europaea leaves. GC-MS anal. of the cold methanolic extract of the leaves of O. europaea L. revealed several unique bioactive compounds, including 9,12-octadecadienoic acid (Z,Z)-, n-hexadecanoic acid, 9-octadecenamide, (Z)-, hexadecanoic acid, 2-hydroxy-1-(hydroxymethyl)ethyl ester, squalene, 2-(2-Hydroxy-2-phenylethyl)-3,5,6-trimethylpyrazine, Benzoic acid, 4-formyl-, Me ester, 2-Methoxy-4-vinylphenol, Vitamin E etc. The FT-IR spectrum revealed distinct fingerprint regions at 3313, 2943, 2831, 1662, 1590, 1449, 1300, 1111, and 1020 cm-1. The fingerprinting region is associated with the presence of several bioactive chems. as determined by GC-MS analyses. The methanolic extract of O. europaea leaves revealed a broader spectrum of antibacterial activity. On the other hand, the spectrum of activity was substantially narrower than that of standard ciprofloxacin disks. In the experiment, the researchers used many compounds, for example, 2,3-Dihydrobenzo[b]furan (cas: 496-16-2HPLC of Formula: 496-16-2).
2,3-Dihydrobenzo[b]furan (cas: 496-16-2) belongs to benzofurans derivatives. Benzofurans are compounds with a planar structure having 10 pi electrons that include the lone pair on oxygen atom, which makes it more susceptible to electrophilic attack. Benzofurans have also made significant and distinctive contributions to biology. They exhibit several biological activities that range from antiviral, antimicrobial, antitumor, anti-inflammatory.HPLC of Formula: 496-16-2
