Abstract

ABSTRACT Artemisia kanashiroi, is an important aromatic medicinal plant that is endemic to China. In the study, the chemical components of essential oil (EO) of A. kanashiroi obtained from different regions in China were analyzed. The results indicated that oxygenated monoterpenes are the predominant components of all EOs, and the major components were 1,8-cineole, camphor, terpine-4-ol, α-terpineol and spathulenol. The chemical composition of EOs exhibited ecological diversity driven by geographical factors. Furthermore, we evaluated the in vitro biological activities of the EOs, including their antioxidant and antibacterial activities. All of the EOs exhibited moderate to potent, broad-spectrum antibacterial and antifungal activities targeting both Gram-positive and Gram-negative bacteria. However, none of the EOs showed significant activity against the tested fungal strains. The antioxidant activity of the EOs was evaluated based on their scavenging activity against 2, 2-diphenyl-1-picrylhydrazyl (DPPH) free radicals, and all of the EOs showed significant concentration-dependent DPPH free radical scavenging activity.

西北金沙蒿挥发油化学成分及抑菌抗氧化活性研究

金沙蒿(Artemisia kanashiroi)是中国特有的重要芳香药用植物。本研究对中国不同产地金杉精油的化学成分进行了分析。结果表明，所有精油的主要成分为氧合单萜烯，主要成分为1,8-桉叶油脑、樟脑、4-松油醇、α-松油醇和匙硫酚。生态系统的化学组成在地理因素的驱动下呈现出生态多样性。此外，我们还评估了EOs的体外生物活性，包括其抗氧化和抗菌活性。所有的EOs都表现出针对革兰氏阳性和革兰氏阴性细菌的中等到有效的广谱抗菌和抗真菌活性。然而，没有一种EOs对所测试的真菌菌株显示出显著的活性。通过对2,2 -二苯基-1-picrylhydrazyl (DPPH)自由基的清除活性评估了EOs的抗氧化活性，所有EOs都显示出显著的浓度依赖性DPPH自由基清除活性。

期刊介绍： Journal of Essential Oil Research ( JEOR) is the major forum for the publication of essential oil research and analysis. Each issue includes studies performed on the chemical composition of some of the 20,000 aromatic plants known in the plant kingdom. JEOR is devoted entirely to all phases of research from every corner of the world by the experts in their field. JEOR''s main areas of focus include: -Analytical chemistry- Biological activity- Biotechnology- Chemical composition- Chemical synthesis- Chemosystematics- Microbiological activity- Plant biochemistry/biosynthesis- Toxicology. Published six times per year, JEOR provides articles on the aromatic principles of a plant or its isolates and are directed toward furthering our readers'' knowledge of the aromatic plant and animal kingdoms.
