Research Efficacy Snapshot

Published efficacy percentages cited in PubMed trials and named-expert reports about Epicatechin. Each line links to the original source.

  • "Machine learning models (backpropagation neural networks and random forest) achieved maximum accuracy >91.89% in predicting storage duration." · Wei Y et al, 2026 PubMed
  • "The oxidative treatment induced a 1.89-fold increase in ROS production compared to the control (corresponding to an 89% up-regulation), representing the largest percentage change observed." · Bianco A et al, 2026 PubMed
  • "Conversely, Ch-EGCG-NPs markedly reduced ROS accumulation compared to free EGCG, lowering ROS levels from 2.24 to 1.06 (≈52.7% reduction) and from 2.24 to 0.66 (≈70.5% reduction), with reductions ranging from 52% to 70.5% in PANC-1 cells and up to 60.3% in HepG2 cells." · Bianco A et al, 2026 PubMed
  • "In this study, UF-HPLC-MS/MS identified 25 potential α-glucosidase (α-G) inhibitors from the acetone extract of bran from 80% black highland barley." · Wu H et al, 2026 PubMed
  • "Both ethanol and aqueous extracts reduced lipid accumulation in mature adipocytes, with inhibition ranging from ∼10% to over 55%, the strongest effect observed in the aqueous extracts from young leaves." · Can AÄŸca A et al, 2026 PubMed
  • "Genotoxicity testing revealed only minor, non-significant increases in DNA fragmentation (<10%)." · Can AÄŸca A et al, 2026 PubMed
  • "Encapsulation efficiency (EE) of Cur was 41.6% for OMVs and 35.9% for EVs, whereas EE of Ant was 25.4% and 24.6%, respectively." · Fang T et al, 2026 PubMed
  • "The incorporation efficiency of EGCp was 27.2% for OMVs and 37.3% for EVs." · Fang T et al, 2026 PubMed
  • "For example, the retention of Cur under oxidative conditions increased from 24.2% in unmodified OMVs to 69.1% in the optimized formulation within 2 h." · Fang T et al, 2026 PubMed
  • "Cellular uptake assays confirmed the OSA-HA coating achieved targeted delivery to inflammatory macrophages, with OSA-HA-modified OMVs exhibiting higher cellular internalization (75.4% at 12 h) than similarly modified EVs (61.8% at 12 h)." · Fang T et al, 2026 PubMed
