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.

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 ...
