Abstract

Abstract Kaempferia is a genus of the Zingiberaceae family containing a rich resource of essential oils (EOs) with various important biological activities. In the present study, the chemical compositions and in vitro antimicrobial activity of the EO of Kaempferia attapeuensis Picheans. & Koonterm were reported for the first time. By the Gas Chromatography-Mass Spectrometry (GC/MS) analysis, a number of 46 compounds were identified in K. attapeuensis rhizomes EO (accounted for 90.61 % of the total content), among which germacrone (25.80%), camphene (18.63%) and α-pinene (10.57%) were the major components. In the in vitro antimicrobial assay, K. attapeuensis rhizomes EO exhibited promising activity against the growth of three Gram-positive bacteria strains (Enterococcus faecalis, Staphylococcus aureus, and Bacillus cereus), three Gram-negative bacteria strains (Escherichia coli, Pseudomonas aeruginosa, and Salmonella enterica) and the yeast strain (Candida albicans) with their MIC values all of 32 µg/mL. In general, the present investigation has provided the foundation for additional research on the chemical compositions and biological effects of K. attapeuensis. GRAPHICAL ABSTRACT

在越南野生生长的 Kaempferia attapeuensis Picheans：新鲜根茎精油的化学成分及其体外抗菌活性

摘要山柰（Kaempferia）是姜科（Zingiberaceae）植物中的一个属，蕴藏着丰富的精油（EOs）资源，具有多种重要的生物活性。本研究首次报道了山柰属植物 attapeuensis Picheans.通过气相色谱-质谱联用（GC/MS）分析，确定了阿塔培根根茎环氧乙烷中的 46 种化合物（占总含量的 90.61%），其中胚芽酮（25.80%）、莰烯（18.63%）和α-蒎烯（10.57%）是主要成分。在体外抗菌试验中，K. attapeuensis 根状茎环氧乙烷对三种革兰氏阳性菌株（粪肠球菌、金黄色葡萄球菌和蜡样芽孢杆菌）、三种革兰氏阴性菌株（大肠杆菌、铜绿假单胞菌和肠炎沙门氏菌）和酵母菌株（白色念珠菌）的生长具有良好的活性，其 MIC 值均为 32 µg/mL。总之，本研究为进一步研究 K. attapeuensis 的化学成分和生物效应奠定了基础。图表摘要
