Alkaloids in Isatis indigotica and their chemotaxonomic significance
Isatis indigotica Fort., belongs to the Brassicaceae family and its leaf is an important Chinese traditional folklore medicine. After many years of research, phytochemical investigations on it have led to the identification of 197 alkaloids, which could serve as valuable chemotaxonomic markers for the identification of I. indigotica. We summarize the chemotaxonomic value of alkaloids, and the results showed that I. indigotica is a typical species in the Brassicaceae family. It has some chemotaxonomic relationships with genera of Brassica L., Arabidopsis (DC.) Heynh., Thellungiella O. E. Schulz, Raphanus L., Lepidium L., together with families of Acanthaceae, Apocynaceae, Nitrariaceae, Orchidaceae and Orchidoideae.
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 Also considered out of scope are studies using outdated and hard to reproduce macromolecular techniques such as RAPDs in combination with standard chemosystematic techniques such as GC-FID and GC-MS.
