Abstract

A new bufadienolide (1), along with ten known bufadienolides (2–11), were isolated from the n-butanol soluble fraction of the crude ethanol extract of Helleborus thibetanus (Ranunculaceae). The structure of the new compound was determined by the analysis of spectroscopic data, including HRESIMS and 1D and 2D NMR. Most of the compounds exhibited remarkable significant cytotoxicity against MDA-MB-231 breast cancer cells, with IC₅₀ values ranging from 0.0007 to 2.586 μM. Notably, compounds 1, 6, and 7 were discovered to exist within the Ranunculaceae family for the first time. Additionally, the chemotaxonomic significance of the isolated compounds was comprehensively explored.

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 Also considered out of scope are studies using outdated and hard to reproduce macromolecular techniques such as RAPDs in combination with standard chemosystematic techniques such as GC-FID and GC-MS.
