Abstract

Artemisia annua is an essential aromatic medicinal plant endemic to China. Here, essential oil was extracted from wild A. annua from Ningxia, China. GC-MS analysis showed that A. annua essential oil was dominated by artemisia ketone, a characteristic compound accounting for 31.26%, followed by eucalyptol (14.89%), camphor (8.69%), myrcene (8.25%) and α-pinene (6.65%). The overall antioxidative potential represented by DPPH and ATBS free radical scavenging rates was weak. The essential oil exhibited good bactericidal activities against Escherichia coli and Staphylococcus aureus and fungicidal activities against Trichophyton rubrum and Epidermophyton floccosum. The minimum inhibitory and microbicidal concentrations were 0.02 mg/mL and 5.12 mg/mL for both bacteria, 0.315% and 2.5% for E. floccosum, and 0.625% and 5% for T. rubrum. The results suggest that A. annua essential oil may be an antimicrobial adjuvant to be applied in pharmaceutical and cosmetic industries.

宁夏野生黄花蒿挥发油的化学成分、抗氧化及抗菌活性研究

黄花蒿(Artemisia annua)是中国特有的重要芳香药用植物。本实验从宁夏野生黄花蒿中提取精油。GC-MS分析表明，黄花蒿挥发油的特征化合物以青蒿酮为主，占31.26%，其次是桉叶油(14.89%)、樟脑(8.69%)、月桂烯(8.25%)和α-蒎烯(6.65%)。以DPPH和ATBS自由基清除率为代表的整体抗氧化能力较弱。该精油对大肠杆菌和金黄色葡萄球菌具有良好的杀菌活性，对红毛癣菌和絮状表皮菌具有良好的杀菌活性。对两种细菌的最低抑菌浓度分别为0.02 mg/mL和5.12 mg/mL，对絮凝乳杆菌的最低抑菌浓度分别为0.315%和2.5%，对红褐乳杆菌的最低抑菌浓度分别为0.625%和5%。结果表明，金盏花精油可作为一种抗菌助剂应用于制药和化妆品行业。

期刊介绍： The aim of Natural Product Research is to publish important contributions in the field of natural product chemistry. The journal covers all aspects of research in the chemistry and biochemistry of naturally occurring compounds. The communications include coverage of work on natural substances of land and sea and of plants, microbes and animals. Discussions of structure elucidation, synthesis and experimental biosynthesis of natural products as well as developments of methods in these areas are welcomed in the journal. Finally, research papers in fields on the chemistry-biology boundary, eg. fermentation chemistry, plant tissue culture investigations etc., are accepted into the journal. Natural Product Research issues will be subtitled either ""Part A - Synthesis and Structure"" or ""Part B - Bioactive Natural Products"". for details on this , see the forthcoming articles section. All manuscript submissions are subject to initial appraisal by the Editor, and, if found suitable for further consideration, to peer review by independent, anonymous expert referees. All peer review is single blind and submission is online via ScholarOne Manuscripts.
