Abstract

The phytochemical investigation of the Scutellaria baicalensis Georgi (S. baicalensis) leaves separation obtained two phenols (1, 2), one coumarin (3), thirteen flavones (4–16). Compounds 7–16 are valuable chemical classification markers in S. baicalensis leaves. Their structures were further determined by spectroscopic method in which compounds 1, 2, 5, and 6 have not yet been reported to be isolated from S. baicalensis, serving as chemical classification markers for S. baicalensis. Furthermore, compounds 1–3, 5, 6, 8 and 10 were successfully isolated from S. baicalensis leaves for the first time. The most important is that the significance of chemical taxonomy was discussed, which can provide theoretical principle on the separation of S. baicalensis leaves for subsequent research.

黄芩叶中的化学成分及其化学分类学意义

对黄芩（S. baicalensis Georgi）叶片分离进行的植物化学研究获得了两种酚类（1、2）、一种香豆素（3）和十三种黄酮类化合物（4-16）。化合物 7-16 是有价值的黄芩叶化学分类标记。通过光谱法进一步确定了它们的结构，其中化合物 1、2、5 和 6 尚未从黄芩中分离出来，因此可作为黄芩的化学分类标记。此外，还首次成功地从黄芩叶中分离出了 1-3、5、6、8 和 10 号化合物。最重要的是探讨了化学分类的意义，为后续研究提供了黄芩叶分离的理论依据。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
