Abstract

Members of the genus (Lauraceae) have aromatic volatiles in their leaves and bark and some species are commercially important herbs and spices. In this work, the essential oils from five species of (, , , and ) growing wild in north central Vietnam were obtained by hydrodistillation, analyzed by gas chromatography and screened for antimicrobial and mosquito larvicidal activity. The leaf essential oil of , rich in β-phellandrene (23.1%) and linalool (32.2%), showed excellent antimicrobial activity (MIC of 32 μg/mL against and ) and larvicidal activity (24 h LC of 17.4 μg/mL on and 14.1 μg/mL against ). leaf essential oil also showed notable antimicrobial activity against Gram-positive bacteria and mosquito larvicidal activity, attributable to relatively high concentrations of neral (11.7%) and geranial (16.6%). Thus, members of the genus from Vietnam have shown promise as antimicrobial agents and as potential vector control agents for mosquitoes.

摘要

该属(樟科)的成员在其叶子和树皮中具有芳香挥发物,一些物种是商业上重要的草药和香料。在这项工作中,通过水蒸馏法从越南中北部野生的 5 种 (、、、和)中提取了精油,通过气相色谱进行了分析,并筛选了其抗菌和杀蚊幼虫活性。叶子精油富含β-水芹烯(23.1%)和芳樟醇(32.2%),表现出优异的抗菌活性(MIC 为 32 μg/mL 对 和 )和杀蚊幼虫活性(24 h LC 为 17.4 μg/mL 对 和 14.1 μg/mL 对 )。叶子精油也对革兰氏阳性菌具有显著的抗菌活性和杀蚊幼虫活性,这归因于较高浓度的橙花醛(11.7%)和牻牛儿醛(16.6%)。因此,来自越南的该属成员有望成为抗菌剂和潜在的蚊虫控制剂。
