To explore the sesquiterpenoids in Curcuma longa L. and their activity related to anti-atherosclerosis. The chemical compounds of the rhizomes of C. longa were separated and purified by multiple chromatography techniques. Their structures were established by a variety of spectroscopic experiments. The absolute configurations were determined by comp...
(1) Background: The florets of Carthamus tinctorius L. are traditionally used as a blood-activating drug and can be used for the treatment of atherosclerosis, but no compounds with anti-atherosclerotic activity have been reported. (2) Methods: This study investigated the chemical compounds from the florets of C. tinctorius. Comprehensive spectrosco...
Black crystalline γ‐CsSnI3 is an ideal light absorption material to replace lead‐based perovskite due to its low biotoxicity and excellent photoelectric properties. However, CsSnI3 is usually prepared in a low humidity inert atmosphere because of its oxidation in air. The severe preparation environment, on the other hand, will surely raise the econ...
This study investigated the chemical components from the florets of Carthamus tinctorius. Five compounds were isolated from C. tinctorius by column chromatography with silica gel and toyopearl HW-40 F, preparative thin-layer chromatography(TLC), and semi-preparative reverse phased high performance liquid chromatography(RP-HPLC). Their structures we...
In this phytochemical study, a novel arborinane-type triterpenoid glycoside (1) and three known megastigmanes (2–4) were isolated from the dried roots of Cyathula officinalis K.C.Kuan. The structures of these compounds were elucidated using NMR spectroscopy. This is the first report of arborinane-type triterpenoids in the Amaranthaceae family. Amon...
