Isolation of astaxanthin monoesters from the microalgae Haematococcus pluvialis by high performance countercurrent chromatography (HPCCC) combined with high performance liquid chromatography (HPLC)
Tereza Fábryová,Tereza Fábryová,Lenka Tůmová,Daniela Correia da Silva,David M. Pereira,Paula B. Andrade,Patrícia Valentão,Pavel Hrouzek,Jiří Kopecký,José Cheel +9 more
TL;DR: This study shows a useful approach for obtaining individual astaxanthin esters from H. pluvialis using high performance countercurrent chromatography (HPCCC), where the lower phase of a biphasic solvent system was used as a mobile phase.

Inhibitory effect of three C-glycosylflavonoids from Cymbopogon citratus (Lemongrass) on human low density lipoprotein oxidation.
TL;DR: It is demonstrated that isoorientin (1) is an effective inhibitor of in vitro LDL oxidation, a key event in the formation of atherosclerotic lesions, and the use of this natural antioxidant may be beneficial to prevent or attenuate atherosclerosis.

TL;DR: It is demonstrated that NoA-induced cell death has attributes of caspase-dependent apoptosis, and NoA exhibits a potent anti-proliferative activity against several human cancer lines, with p53-mutated cell lines being even more sensitive.
Purification of lutein from the green microalgae Chlorella vulgaris by integrated use of a new extraction protocol and a multi-injection high performance counter-current chromatography (HPCCC)
Tereza Fábryová,Tereza Fábryová,José Cheel,David Kubáč,Pavel Hrouzek,Dai Long Vu,Lenka Tůmová,Lenka Tůmová,Jiří Kopecký +8 more
TL;DR: In this article, the lower phase (LP4) of the biphasic solvent system composed of n-heptane-ethanol-water (5:4:1.5, v/v/v) was used both as a solvent for microalgae biomass extraction and as a mobile phase for lutein isolation using high performance counter-current chromatography (HPCCC).
