Impact of altitudinal gradients on chemical profiling and pesticidal activities of Hedychium spicatum Sm
Hedychium spicatum Sm. is an endangered herb which grows preferably in humid tropics and subtropics known for its distinct camphoraceous flavour and medicinal properties. The essential oils of H. spicatum rhizomes from six different natural habitats at different altitudes in Uttarakhand, India were analyzed. Twenty compounds were identified, accounting for 87.4–98.5% of the essential oils, with 1,8-cineole (33.4–41.9%), α-terpinene (39.6%), camphor (31.4%), and linalool (29.9%), being the prevalent major constituents of all accessions. HS-ALM (H. spicatum rhizomes Almora essential oil), HS-DDN (H. spicatum rhizomes Dehradun essential oil), HS-PAU (H. spicatum rhizomes Pauri essential oil), HS-TEH (H. spicatum rhizomes Tehri essential oil), and HS-USN (H. spicatum rhizomes Udham Singh Nagar essential oil) were dominated by oxygenated monoterpenes with 43.1–74.0%, respectively. In contrast, in HS-PIT (H. spicatum rhizomes Pithoragarh essential oil), hydrogenated monoterpenes dominated 57.8% of the total oil constituents. All accessions were assessed for significant nematicidal potential against Meloidogyne incognita and insecticidal potential against Spodoptera litura. The proteins/enzymes used for validation using docking studies were acetylcholinesterase (PBD ID: IC2O) and carboxylesterase (PDB ID: 1CI8). The study produced significant outcomes, showing the binding energy estimation of tested oil components to active sites supported the structure-activity relationship with bioinformatics tools.
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.
