Influence of Different Washing Hair Procedures in the Quantitative Determination of THC and THCCOOH

Drug Testing and Analysis, Volume 18, Issue 6, Page 777-784, June 2026.
Different hair decontamination protocols significantly affect THC quantification, with marked analyte loss—particularly after aqueous‐organic washing—whereas THCCOOH remains stable. These findings highlight the risk of misinterpretation and the need for standardized washing procedures in hair analysis.

Hydroxy‐α‐Sanshools From Zanthoxylum bungeanum Maxim. Alleviate Obesity in Mice via the Regulation of Appetite and Gut Microbiota

Food Science &Nutrition, Volume 14, Issue 6, June 2026.
Hydroxy‐alpha‐sanshool could modulate the expression of appetite‐related factors and the composition of intestinal microbiota in mice fed with a high‐fat diet by regulating food intake and maintaining energy homeostasis, which is consistent with the involvement of the gut‐brain axis in this regulatory mechanism.
