A new anthraquinone, 1,6,7-trihydroxy-3-methoxyanthraquinone, along with three known compounds methyl trans-p-hydroxycinnamate, eugenin and 1,3,6-trihydroxy-8-methylanthraquinone, were isolated from the subterranean rhizomes of Gladiolus gandavensis Van Houtt. Their structures were established on the basis of spectroscopic data including 2D NMR techniques and chemical methods. 
New polyacetylene and other compounds from Bupleurum chinense and their chemotaxonomic significance
This is the first report of the presence of compounds 2 and 6 in the Bupleurum spp.. Chemotaxonomic significance of these compounds is described herein. Expand
Anthraquinones from Gladiolus gandavensis
Five new anthraquinones have been obtained from the ethanolic extracts of the subterranean corms of Gladiolus gandavensis Van Houtt on the basis of spectral data. Expand
Shedding the light on Iridaceae: Ethnobotany, phytochemistry and biological activity
A comprehensive overview on the isolated phytochemicals and reported biological activities for the most popular genera of Iridaceae is provided and the large scale cultivation of the economically important members is highlighted herein. Expand
Potentials of Gladiolus corms as an antimicrobial agent in food processing and traditional medicine
The somewhat selective antimicrobial effects of the extracts do however; suggest the basis for the use of these corms, but the presence of cardiac glycosides - a cardiotoxin, calls for caution in their use. Expand
Ab initio tools for the accurate prediction of the visible spectra of anthraquinones.
The UV/vis absorption spectra of 101 anthraquinones solvated in two protic solvents has been theoretically predicted using the time-dependent density functional theory for excited state calculations and the polarizable continuum model for evaluating bulk solvent effects. Expand
Revisiting the relationship between the bond length alternation and the first hyperpolarizability with range‐separated hybrid functionals
For the dodecamer, both HF and PBE0 are unable to foresee even the qualitative evolution of the first hyperpolarizability when varying the BLA, and LC‐ωPBE provides (non)linear optics properties in agreement with MP2 results, especially for the longer chains. Expand
Assessment of the efficiency of long-range corrected functionals for some properties of large compounds.
It turns out that both LC-DFT and CAM-B3LYP provide an accurate bond length alternation for polyacetylene and polymethineimine, although for the latter they decrease slightly too rapidly with chain length. Expand
