Abstract

To evaluate the antibacterial activity and chemical constituents of the essential oil from the artemisia argyi grown in Qichun (China). METHODS: Steam distillation method was used to extract volatile oil from Artemisia argyi. The antibacterial effect of the volatile oil was investigated by the plate coating method and the double gradient liquid dilution method. Gas chromatography-mass spectrometry(GC-MS) was applied for the identification of chemical constituents in volatile oil from Artemisia argyi and the relative percentage of each component was calculated by area normalization. RESULTS: The essential oil from artemisia argyi grown in Qichun (China) has significant antibacterial activity against staphylococcus aureus, pseudomonas aeruginosa, salmonella, candida albicans, aspergillus niger and aspergillus flavus. And fifty chemical components were detected in the essential oil, and twenty compounds were identified, accounting for 95.95% of total essential oil. And the artemisol in artemisia argyi grown in Qichun (China) was found to be the highest compared with the same species from other producing areas. CONCLUSION: The essential oil from artemisia argyi grown in Qichun (China) was a potent antibacterial plant extract with potential applications as an antibacterial drugs or food preservative.

Highlights

Essential oils are present in various aromatic plants that are commonly grown in tropical and subtropical countries

The major constituents of essential oils are terpenes, terpenoids and aromatic and aliphatic compounds, which are characterized as low-molecular-weight aroma chemicals.

Summary

Introduction

Essential oils are present in various aromatic plants that are commonly grown in tropical and subtropical countries. Several techniques have been used to obtain essential oils from the plant, including steam distillation, solvent extraction, cold pressing and supercritical fluid extraction. [1] Among these techniques, essential oils are most commonly obtained by a steam distillation method. The major constituents of essential oils are terpenes, terpenoids and aromatic and aliphatic compounds, which are characterized as low-molecular-weight aroma chemicals. Essential oils and some of their components have been widely used in various products, including cosmetics, household cleaning products and air fresheners, hygiene products, agriculture, and food, as well as in medicinal uses. Artemisia argyi is widely distributed throughout China, which is one of the most popular plants in Chinese traditional medicine and frequently used for diseases treatment such as eczema, inflammation, hemostasis, menstruation-related symptoms, and tuberculosis.
