Aggregation of Modified Glucuronoxylan in Water and DMSO
Biopolymers, Volume 117, Issue 3, May 2026.Neutron scattering study of dispersibility of glucuronoxylan and modified glucuronoxylan, in water and dimethyl sulfoxide (DMSO). ABSTRACT Glucuronoxylans are known to be only partly soluble in aqueous media. Chemical modification often aims to improve solubility, yet observations of aggregation even of the modified xylans are not uncommon.

Sample Preparation and Separation of Lignans by Liquid Chromatography
Journal of Separation Science, Volume 49, Issue 5, May 2026.ABSTRACT Lignans are important phytochemicals found mostly in the resins of coniferous trees, but are also introduced into human diets through foods such as sesame seeds and extra‐virgin olive oil. They are pharmacologically interesting mainly because of their antioxidant activities, and they have also been shown to have cytotoxic and antimicrobial ...
