Three new sodium salts of iridoid acids, deacetylasperulosidic acid sodium salt (1), teneoside D (2), and teneoside E (3) were isolated from the leaves of Hedyotis tenelliflora Blume (Rubiaceae), together with seven known iridoids, 6alpha-hydroxygeniposide (4), 6beta-hydroxygeniposide (5), 6-O-methyldeacetylasperulosidic acid methyl ester (6), 6-O-methylscandoside methyl ester (7), 6alpha-methoxygeniposidic acid (8), daphylloside (9), and mollugoside methyl ester (10). Their chemical structures were elucidated by 1D and 2D NMR spectroscopy, as well as HR-ESI-MS analysis.

The WRINKLED1 (WRI1) transcription factor controls carbon flow in plants through regulating the expression of glycolysis and fatty acid biosynthesis genes. The role of Gossypium hirsutum WRINKLED1 (GhWRI1) in seed-oil accumulation still needs to be explored. Multiple sequence alignment of WRI1 proteins confirmed the presence of two conserved AP2 domains.

Harmful algal biotoxins in the marine environment are a threat to human food safety due to their bioaccumulation in bivalve shellfish. Whilst official control monitoring provides ongoing risk management for regulated toxins in live bivalve molluscs, no routine monitoring system is currently in operation in the UK for other non-regulated toxins. To assess the potential presence of such compounds, a systematic screen of bivalve shellfish was conducted throughout Great Britain.

Four previously undescribed pentacyclic triterpenoid saponins, pannosides F-I (-), were isolated from the halophyte L. (), and their chemical structures were elucidated using 1D and 2D NMR spectroscopy and mass spectrometry. Comprehensive structural analysis revealed the presence of distinct aglycone and glycosidic moieties, along with complex acylation patterns.
