Chemical, chemophenetic and antiproliferative studies of Cattleya purpurata
This study investigates the phytochemical composition, cytotoxic activity, and chemophenetic relationships of Cattleya purpurata, a prominent Brazilian orchid. Despite its widespread cultivation for ornamental and commercial purposes, the phytochemical profile of C. purpurata remains underexplored. Phytochemical analysis led to the isolation and identification of 12 compounds using nuclear magnetic resonance (NMR) spectroscopy: the triterpene 24-methylenecycloartanol (1), the steroids β-sitosterol (2), stigmasterol (3), and campesterol (4), the phenanthrenequinones phocanthone (5) and ephemeranthoquinone (8), the stilbenoids stilbostemin J (6) and 3′-O-methylbatatasin III (10), the dihydrophenanthrenes coelonin (11) and lusianthridin (12), and the phenolic acids salicylic acid (7) and phloretic acid (9). Dereplication studies employing ultra-high-performance liquid chromatography coupled with high-resolution time-of-flight mass spectrometry (UHPLC-QToF-HR-MS/MS) enabled the putative identification of additional compounds, the alkaloid feruloytyramine (13), the monoterpene lactone loliolide (14), the nucleoside methylsulfinyladenosine (15), the stilbene gigantol (16), and the phenolic compounds methoxyhydroxytyrosol (17) and syringic acid glucosyl ester (18). Cytotoxicity assays were conducted on human HeLa cancer cells and non-tumor VERO cell lines using the crude extract and fractions. Chemophenetic analysis suggests a close relationship between C. purpurata and the related species C. tigrina and C. intermedia, supported by shared morphological and genetic traits that facilitate even natural hybridization. These findings underscore C. purpurata as a valuable taxon for chemophenetic studies within the Cattleya genus.
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.
