Structural modification of berberine alkaloid and their hypoglycemic activity

open access: yesJournal of Functional Foods, 2014
Berberine (BBR), a major active component of natural plant product, has recently been demonstrated to be clinically effective in alleviating type 2 diabetes mellitus (T2DM). In this study, BBR and 8-alkylberberine were successively halogenated with bromine, iodine, chlorine under various conditions.

Transcriptional Regulation of the Novel Theacrine Synthase Gene CsTcS2 by the CsTINY–CsWRKY33 Module Underpins Theacrine Biosynthesis in Camellia sinensis

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Theacrine (1,3,7,9‐tetramethyluric acid) is a purine alkaloid detected in multiple wild and specialised tea germplasms (Camellia sinensis) from South China, including Kucha. However, the molecular mechanisms governing its biosynthesis remain poorly understood. Here, we identify CsTcS2 as a novel theacrine synthase in tea plant.

Evaluation of HSYA and Carthamin Accumulation in Safflower (Carthamus tinctorius L.) Induced by Chemical Mutagens (EMS and SA) in M1 and M2 Generations

open access: yesPlant Breeding, EarlyView.
ABSTRACT Historically cultivated for medicinal and dyeing purposes, safflower (Carthamus tinctorius L.) saw a shift towards widespread oilseed production after the 1920s due to the growing importance of oils. However, there is a renewed interest in its medicinal and dyeing properties today.

Colon‐Targeted Berberine Nanoparticles‐Embedded Yeast Microcapsules for Regulation of Gut Immunity of Sepsis

open access: yeseFood, Volume 7, Issue 4, August 2026.
A schematic representation illustrating the preparation of BGNP@YM and its therapeutic effects on septic mice induced by lipopolysaccharide (LPS). (A) BBR is first encapsulated within GNPs to form BGNPs with anti‐inflammatory activity, which are subsequently coated with YM via chemical precipitation to obtain the BGNP@YM oral delivery system.
