Many indigenous plants of the Philippines, including essential oil-bearing species, remain phytochemically and pharmacologically unexplored. In this study, the chemical composition of leaf essential oils (EOs) hydrodistilled from (Lauraceae) and (Piperaceae) was determined using dual-column (HP-5MS/DB-WAX)/dual-detector gas chromatography and mass spectrometry analysis. Caryophyllene oxide (15.751/16.018%) was identified as the main compound in EO, followed by β-caryophyllene (11.130/11.430%) and α-copaene (9.039/9.221%). Ishwarane (25.937/25.280%), nerolidol (9.372/10.519%) and 3-ishwarone (6.916/2.588%) were the most abundant constituents of EO. Additionally, the in vitro growth-inhibitory activity of the EOs in the liquid and vapour phases against was evaluated using the broth microdilution volatilisation assay. Although the results showed no anti-staphylococcal effect, the presence of various bioactive compounds in both EOs suggests their potential future use in industrial applications.
菲律宾的许多本土植物，包括含精油的物种，在植物化学和药理学方面仍未得到充分研究。在本研究中，使用双柱（HP - 5MS/DB - WAX）/双检测器气相色谱和质谱分析法，测定了从樟科的[某植物]和胡椒科的[某植物]水蒸馏得到的叶精油（EOs）的化学成分。氧化石竹烯（15.751/16.018%）被确定为[樟科植物]精油中的主要化合物，其次是β - 石竹烯（11.130/11.430%）和α - 可巴烯（9.039/9.221%）。伊施烷（25.937/25.280%）、橙花叔醇（9.372/10.519%）和3 - 伊施酮（6.916/2.588%）是[胡椒科植物]精油中含量最高的成分。此外，使用肉汤微量稀释挥发法评估了精油在液相和气相中对[某菌]的体外生长抑制活性。尽管结果显示没有抗葡萄球菌作用，但两种精油中存在的各种生物活性化合物表明它们未来在工业应用中具有潜在用途。
