@article{Van_Ngo_Nguyen_Nguyen_Pham_Nguyen_Thieu_Dang_Nguyen_Le_Le_Dam_2022, title={Chemical composition, antibacterial and antioxidant activities of acetone extract from the branches and leaves of Jasminum annamense subsp. annamense (Oleaceae)}, volume={14}, url={https://www.updatepublishing.com/journal/index.php/jp/article/view/7418}, DOI={10.25081/jp.2022.v14.7418}, abstractNote={<p><em>Jasminum annamense </em>subsp. <em>annamense</em> is a rare subspecies of <em>Jasminum annamense</em> belonging to the Oleaceae family. The aims of this study were to address the chemical profiles, antibacterial and antioxidant activities of acetone extract isolated from branches and leaves <em>Jasminum annamense </em>subsp. <em>annamense</em> for the first time. The chemical constituents of acetone extracts of studied samples were investigated by gas chromatography-mass spectrometry. There were a total of 24 components identified from the leaf extract, including lup-20(29)-en-3-one (27.93%), levodopa (19.68%), <em>trans</em>-cinnamic acid (7.58%), linolenic acid (6.35%) as the major compounds. Meanwhile, 26 components were reported from the branch extracts which are sorbitol (25.74%), lupeol (13.3%), <em>cis</em>-vaccenic acid (6.97%), glycerin (6.35%) and n-hexadecanoic acid (5.86%) were the main components. The two acetone extracts of <em>J. annamense </em>subsp. <em>annamense</em> exhibited antibacterial effect against <em>Bacillus cereus, Escherichia coli, Salmonella enteritidis </em>and <em>Staphylococcus aureus</em> based on disk diffusion assay. In addition, leaf and branch extracts of the studied species also display notable antioxidant activity in the ABTS assay with IC<sub>50 </sub>values of 311.75±3.39 and 664.46±3.732 µg/ml, respectively. This is the first report on the chemical and biological properties of <em>J. annamense </em>subsp. <em>annamense</em> and provides a promising perspective for developing good sources of antioxidant and antimicrobial compounds against both Gram positive and negative bacteria.</p>}, journal={Journal of Phytology}, author={Van, Hong Thien and Ngo, Ngoc Hung and Nguyen, Ngoc Thuan and Nguyen, Ngoc An and Pham, Tan Viet and Nguyen, Hanh Thi Dieu and Thieu, Gia Linh and Dang, Thi Hoai Thuong and Nguyen, Quoc Hung and Le, Thanh Tho and Le, Van Son and Dam, Sao Mai}, year={2022}, month={Mar.}, pages={17–23} }
