Production of Bixin‐Rich Extracts From Annatto Seeds via Ethanol–Water Extraction Integrated With Ultrafiltration Technology

Chemistry &Biodiversity, Volume 23, Issue 10, October 2026.
Ethanol–water extraction followed by 5 kDa ultrafiltration yields a bixin‐rich annatto extract with 97.9% bixin rejection, 94.2% recovery in the retentate, and an enrichment factor of 1.29. Fouling analysis indicates an important contribution from cake formation, highlighting the role of membrane–solute interactions in the selective concentration of ...

Component Analysis Based on UHPLC‐Q‐Exactive‐Orbitrap/MS and Immune Regulatory Activity Assessment by an LPS‐Stimulated Macrophages Model of Sacha Inchi Shell (Plukenetia volubilis Linneo) Extract

Chemistry &Biodiversity, Volume 23, Issue 10, October 2026.
The extract of SISE was characterized by LC‐MS, and 44 constituents were identified. Immune function evaluation confirmed that SISWE has a bidirectional immune regulation effect. Further mechanistic studies revealed that SISWE alleviates inflammatory response via suppressing NF‐KB and MAPK signaling pathways.

Caffeoylquinic acids from leaves of Etlingera species (Zingiberaceae)

LWT - Food Science and Technology, 2009
Abstract 3-O-caffeoylquinic acid, 5-O-caffeoylquinic acid (chlorogenic acid), and 5-O-caffeoylquinic acid methyl ester, as elucidated by 1H and 13C NMR, were isolated from leaves of Etlingera elatior. This is the first report of caffeoylquinic acids (CQA) including chlorogenic acid (CGA) in Zingiberaceae.

Untargeted Metabolomics‐Based Analysis of Metabolic Differences in Different Parts of Bidens bipinnata L.

Chemistry &Biodiversity, Volume 23, Issue 10, October 2026.
Untargeted UPLC‐Q‐TOF‐MS metabolomics reveals that stems, leaves, and fruits of Bidens bipinnata L. harbor strikingly distinct metabolic landscapes. Among 1028 annotated metabolites, flavonoids including luteolin, quercetin, and kaempferol‐3‐O‐rutinoside are preferentially enriched in leaves via flavone and flavonol biosynthesis pathways.
