A new lignanamide (1), lyciumamide K, together with four known analogues (2-5), was isolated from the root of Lycium yunnanense Kuang. Based on HR-ESI-MS, NMR spectral data and quantum chemistry ECD calculations, the structure of this new compound was confirmed, including its absolute configuration.
The aims of this study were to complement the current knowledge on the antioxidative composition of alcohol extracts from the fruits of Lycium barbarum and to evaluate their antioxidant activities. Three new dimers of phenolic amides, named lyciumamides A (3), B (4), and C (5), together with two
Lyciumamide A (LyA), a dimer of phenolic amide isolated from the fruits of Lycium barbarum, has been confirmed to possess potent antioxidant activity. This study was aimed to investigate the neuroprotection and molecular mechanisms of LyA against cerebral ischemia/reperfusion (I/R) injury via
The fruits of Lycium barbarum have a long history as an edible and medicinal food in Asian regions and have multiple consumption methods, the polysaccharides (LBPs) are commonly considered as their major immunological constituents. The current study revealed that the total phenolic amide moieties
Seven new lignanamides, lyciumamides D-J (1-4 and 9-11), together with nine known analogues (5-8 and 12-16), were isolated from the root bark of Lycium chinense. The structures of the isolated compounds were elucidated on the basis of NMR spectroscopic and HRESIMS data. All isolated compounds were
Four new phenolic amides, 4-O-methylgrossamide (1), (E)-2-(4,5-dihydroxy-2-{3-[(4-hydroxyphenethyl)amino]-3-oxopropyl}-phenyl)-3-(4-hydroxy-3-methoxyphenyl)-N-(4-hydroxyphenethyl)acryl-amide (2), (Z)-lyciumamide C (3), (Z)-thoreliamide B (4), together with thirteen known phenolic amides were
