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： Biochemical Systematics and Ecology is devoted to the publication of original papers and reviews, both submitted and invited, in two subject areas: I) the application of biochemistry to problems relating to systematic biology of organisms (biochemical systematics); II) the role of biochemistry in interactions between organisms or between an organism and its environment (biochemical ecology). In the Biochemical Systematics subject area, comparative studies of the distribution of (secondary) metabolites within a wider taxon (e.g. genus or family) are welcome. Comparative studies, encompassing multiple accessions of each of the taxa within their distribution are particularly encouraged. Welcome are also studies combining classical chemosystematic studies (such as comparative HPLC-MS or GC-MS investigations) with (macro-) molecular phylogenetic studies. Studies that involve the comparative use of compounds to help differentiate among species such as adulterants or substitutes that illustrate the applied use of chemosystematics are welcome. In contrast, studies solely employing macromolecular phylogenetic techniques (gene sequences, RAPD studies etc.) will be considered out of scope. Discouraged are manuscripts that report known or new compounds from a single source taxon without addressing a systematic hypothesis. Also considered out of scope are studies using outdated and hard to reproduce macromolecular techniques such as RAPDs in combination with standard chemosystematic techniques such as GC-FID and GC-MS.
