Abstract

Alocasia cucullata (Lour.) Schott is a member of the Araceae family and is characterized by its unique leaf morphology and vibrant flowers; thus, it is a valuable addition to gardens and interior decor. However, A. cucullata may contain toxic compounds, including calcium oxalate crystals, lectins, and alkaloids, and their distribution within the plant tissues remains poorly understood. In this study, untargeted metabolomics was used to analyse the distribution of the bioactive compounds across the roots, stems, leaves, and guttation of A. cucullata. The toxic effects of these tissues on the MDA-MB-231 human breast cancer cell line were evaluated using the MTT assay. Microscopic techniques were utilized to examine the microstructure of the guttation and stems, and the focus was on the morphology of the calcium oxalate crystals. Liquid chromatography and ELISA kits were used to quantify the calcium oxalate and lectin contents in the various tissues. The results demonstrated that the active constituents, primarily fatty acids, phenylpropanoids, flavonoids, peptides, and alkaloids, were concentrated in the roots. Notably, guttation exhibited no toxicity and lacked both calcium oxalate crystals and significant lectin levels. This research enhances the understanding of the bioactive composition and safety profile of A. cucullata and provides a theoretical foundation for future scientific investigations and safe cultivation, with implications for both scientific and industrial applications.

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.
