Author(s): Hea, Yi; Zhang, Li; Zhao, Ming; Tsai, Sam-Hip; Zong, Yuying; Che, Chun-Tao
Subject(s): Eurycorymbus cavaleriei Sapindaceae Phenolic compound
Abstract: Three new phenolic compounds, eurycorymboside A (1), eurycorymboside B (6), and eurycorymbic acid (8) were isolated from the stem part of Eurycorymbus cavaleriei (Sapindaceae), along with five known phenolic compounds, glucosyringic acid (2), vanillic acid 4-O-β-D-glucoside (3), koaburaside (4), tachioside (5), and 4-hydroxy-3,5-bis(3-methyl-2-butenyl)benzaldehyde (7). The structures were established on the basis of spectral analysis. The antioxidant activities of the compounds 1-6 were evaluated by the DPPH free radical scavenging assay. Compound 4 exhibited antioxidant activity with an IC50 value of 9.0 μM. Compound 4 also showed weak inhibitory activity against influenza A neuraminidase
