The hexane-ethyl acetate-methanol-water system for the separation of theaflavins from black tea (Camellia sinensis) using high-speed counter-current chromatography

Ceylon Journal of Science, 2016
Theaflavins (TFs) from black tea leaves were separated using high-speed countercurrent chromatography (HSCCC). Isobutyl methyl ketone (4-methyl-2-pentanone) was used to separate the TFs from a hot water extract of black tea leaves.

A Protocol for Characterizing Comprehensive Two‐Dimensional Liquid Chromatography Systems

Journal of Separation Science, Volume 49, Issue 5, May 2026.
ABSTRACT Comprehensive two‐dimensional liquid chromatography (LC × LC) is an effective strategy to increase peak capacity and improve separation performance for complex samples, offering a valuable alternative to conventional one‐dimensional liquid chromatography (1D‐LC).

SR‐B1‐Mediated Transplacental Transfer of Hydrophobic Toxicants Disrupts Fetal Development During Barriergenesis

Advanced Science, Volume 13, Issue 23, 23 April 2026.
This study maps the spatiotemporal distribution of hydrophobic toxicants and endogenous metabolites in the developing placenta and fetus. By integrating mass spectrometry imaging with snRNA‐seq, we identify SR‐B1 as a key transporter driving early‐gestation xenobiotic transfer and reveal a critical exposure window associated with persistent fetal ...

Long‐term effects of moderate and severe hypoxia on growth, intermediary metabolism, monoamine neurotransmitters, and fatty acids in juveniles of coho salmon, Oncorhynchus kisutch

Journal of the World Aquaculture Society, Volume 57, Issue 2, April 2026.
Abstract Hypoxia concerns have increased in recent decades, reducing fish fitness and becoming a critical challenge in salmon aquaculture. We investigated the effect of long‐term hypoxia on the physiological response of coho salmon (Oncorhynchus kisutch).

Antimycobacterial and Nitric Oxide Production Inhibitory Activities of Goyazensolide and Centratherin Isolated From Eremanthus crotonoides by High‐Speed Countercurrent Chromatography

Chemistry &Biodiversity, Volume 23, Issue 3, March 2026.
ABSTRACT In this study, bioassay‐guided fractionation of the ethanolic extract from Eremanthus crotonoides leaves enabled the isolation of two bioactive sesquiterpene lactones, centratherin and goyazensolide, which were evaluated for their antimycobacterial and anti‐inflammatory properties.
