Rhodiosin and herbacetin in Rhodiola rosea preparations: additional markers for quality control?
Pharmaceutical Biology, 2019 Context: Rhodiola rosea L. (Crassulaceae) is well-known to contain flavonoids such as the herbacetin derivative rhodiosin. However, flavonoids are not typically used in quality control. Objective: This study analyses two flavonoids of R.

Indigenous amino acids in primitive CR meteorites [PDF]
arXiv, 2008 CR meteorites are among the most primitive meteorites. In this paper, we report the first measurements of amino acids in Antarctic CR meteorites, two of which show the highest amino acid concentrations ever found in a chondrite. EET92042, GRA95229 and GRO95577 were analyzed for their amino acid content using high performance liquid chromatography with ...

Harnessing an elastic flow instability to improve the kinetic performance of chromatographic columns [PDF]
arXivDespite decades of research and development, the optimal efficiency of slurry-packed HPLC columns is still hindered by inherent long-range flow heterogeneity from the wall to the central bulk region of these columns. Here, we show an example of how this issue can be addressed through the straightforward addition of a semidilute amount (500~ppm) of a ...
