posted on 2012-10-02, 00:00 authored by Yi Hea, Li Zhang, Ming Zhao, Sam-Hip Tsai, Yuying Zong, Chun-Tao CheThree 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
