WebThe chemical composition and anti-inflammatory activity of the endemic Lysimachia baviensis were investigated for the first time in this study. A phytochemical fractionation of the methanol extract of L. baviensis resulted in the isolation of a new stilbene (bavienside A, 1) and two new chalcone glycosides (baviensides B and C, 2 and 3).Their structures … WebApr 6, 2024 · In combination with AG and cold stress, the unique downregulated genes and transcription factors with the highest expression (-9.5 to -15.3 log2FC) were OS11G0635300 (cytochrome P450), OS09G0551400 (serine/threonine-protein kinase receptor precursor), and OS07G0525900 (chalcone and stilbene synthases).
