Abstract

Artemisia frigida is an endemic plant that only grows in China and its phytochemistry has never been fully appreciated and sufficiently studied. In the present study, a phytochemical investigation on the aerial parts of A. frigida resulted in the isolation of a new norlignan (1), together with twelve known constituents (2–13). Their structures were established by NMR spectroscopic analysis and comparison of their data with previous literature. Compound 1 existed as racemic mixtures, and all of the compounds were isolated from A. frigida for the first time except compounds 2–5. Moreover, the chemotaxonomic significance corresponding to the above compounds was investigated.

一种新的冷蒿去甲脂素及其它化合物

冷蒿（Artemisia frigida）是中国特有的植物，其植物化学性质尚未得到充分认识和研究。在本研究中，对冷田中气生部分进行了植物化学研究，分离出一种新的褐皮素(1)，以及12种已知成分（2-13）。通过核磁共振波谱分析和与文献数据的比较，确定了它们的结构。化合物1为外消旋混合物，除化合物2 ~ 5外，其余化合物均为首次从冷蒿中分离得到。并对上述化合物的化学分类意义进行了探讨。

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 Also considered out of scope are studies using outdated and hard to reproduce macromolecular techniques such as RAPDs in combination with standard chemosystematic techniques such as GC-FID and GC-MS.
