Abstract
Nineteen compounds were isolated from Xylanche himalaica., including ten triterpenoids (1–10), one phytosterol (11), five lignans (12–16), two phenylethanoid glycosides (17–18), and one iridoid glycoside (19). Their structures were characterized through NMR spectroscopy and compared with literature data. Nine compounds (1–3, 8–9, 12, 14–15, 19) were first reported in the family Orobanchaceae; Ten compounds (1–3, 8–9, 11–12, 14–15 and 19) have never been found in the genus Xylanche and this plant before. Compounds 1 and 2 were discovered as natural products for the first time. Compound 19 is the first report of iridoid glycoside in this plant. Furthermore, the chemotaxonomic significance of these compounds was discussed.
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 Also considered out of scope are studies using outdated and hard to reproduce macromolecular techniques such as RAPDs in combination with standard chemosystematic techniques such as GC-FID and GC-MS.
