摘要

近十年来,人们对青蒿属植物及其化学成分的研究得到了广泛的关注。艾草(Artemisia abrotanum L.)和苦艾草(Artemisia absinthium L.)是传统的药用芳香植物,具有很强的消化活性,这是由各种植物化学物质决定的。本研究旨在测定两种蒿属植物不同生长阶段样品中多酚类物质含量的变化,并评价其甲醇提取物的体外抗氧化活性。采用分光光度法和高效液相色谱- pda技术对样品进行植物化学分析,采用DPPH、ABTS、FRAP和CUPRAC测定样品的抗氧化活性。在不同的植被阶段,蒿属植物中酚类化合物的多样性存在显著差异。酚类化合物以绿原酸、3,5-二咖啡酰奎宁酸和芦丁为主。该研究对不同生长阶段的青蒿类植物酚类化合物和黄酮类化合物的组成、潜在的药理作用和抗氧化活性提供了有价值的见解。这些发现有助于了解从青蒿类植物中提取的草药的质量和安全性。

Phenolic Diversity and Antioxidant Activity of Artemisia abrotanum L. and Artemisia absinthium L. during Vegetation Stages
Over the past ten years, particular attention has been paid to Artemisia L. genus plants and their chemical composition. Artemisia abrotanum L. and Artemisia absinthium L., which are traditional medicinal, aromatic plants with a strong digestive activity that is determined by the various phytochemicals. The research aim was to determine the variation in polyphenols in the samples of different vegetation stages of two Artemisia species and to evaluate the antioxidant activity of methanolic extracts in vitro. Phytochemical analysis of the Artemisia samples was carried out using spectrophotometric methods and HPLC-PDA techniques, while antioxidant activity was determined using DPPH, ABTS, FRAP, and CUPRAC assays. Significant differences in the diversity of phenolic compounds were found among Artemisia species during vegetation stages. Chlorogenic acid, 3,5-dicaffeoylquinic acid, and rutin were predominant among the phenolic compounds. The study provides valuable insights into the composition of phenolic compounds and flavonoids in Artemisia plants at different growth stages, shedding light on their potential pharmacological effects and antioxidant activities. These findings contribute to the knowledge of the quality and safety of herbal materials derived from Artemisia species.

期刊介绍: Separations (formerly Chromatography, ISSN 2227-9075, CODEN: CHROBV) provides an advanced forum for separation and purification science and technology in all areas of chemical, biological and physical science. It publishes reviews, regular research papers and communications. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. There is no restriction on the length of the papers. The full experimental details must be provided so that the results can be reproduced. There are, in addition, unique features of this journal: Manuscripts regarding research proposals and research ideas will be particularly welcomed. Electronic files and software regarding the full details of the calculation and experimental procedure, if unable to be published in a normal way, can be deposited as supplementary material. Manuscripts concerning summaries and surveys on research cooperation and projects (that are funded by national governments) to give information for a broad field of users. The scope of the journal includes but is not limited to: Theory and methodology (theory of separation methods, sample preparation, instrumental and column developments, new separation methodologies, etc.) Equipment and techniques, novel hyphenated analytical solutions (significantly extended by their combination with spectroscopic methods and in particular, mass spectrometry) Novel analysis approaches and applications to solve analytical challenges which utilize chromatographic separations as a key step in the overall solution Computational modelling of separations for the purpose of fundamental understanding and/or chromatographic optimization
