UHPLC–MS Method Used to Detect Purine Metabolites and Study Severe Biological Disorders
December 5th 2023A recent study published in the Journal of Separation Science reveals how ultrahigh-performance liquid chromatography tandem mass spectrometry (UHPLC–MS/MS) could be used to detect and quantify purine metabolites.
A Rapid Approach to Extract and Separate Compounds from Juglands mandshurica Maxim. Exocarp
November 16th 2023This study employed an integrated method of homogenization-ultrasound-assisted extraction followed by high-speed countercurrent chromatography for efficient separation of naphthoquinones and diarylheptanes from green walnut husks.
Machine Learning Models Help Researchers Predict the Ages of Ginseng
November 9th 2023To combat fraudulent sales of low-aged ginseng disguised as high-aged ginseng, scientists from Shanghai University of Traditional Chinese Medicine created machine learning models to predict the ages of ginseng samples.
Improved Solvent Screening for Precise Chromatographic Fractionation of Complex Samples
November 8th 2023An efficient solvent system screening approach that streamlines fractionation of compounds with similar UV absorption eliminates the need for individual partition coefficient calculations, and coupled with preparative HPLC purification, led to the isolation of seven c-glycosyl flavonoids and an amino acid from barley seedlings.
