摘要Three new compounds, namely, (+)-dihydrodehydrodiconiferyl alcohol 4-O-beta-(6"-O-galloyl)-glucopyranoside (1), 4,4'-O-dimethylellagic acid 3-(2"-O-acetyl)-alpha-rhamnopyranoside (2), and ethyl O-beta-(6'-galloyl)-glucopyranoside (3), together with eleven known ones, were isolated from the stem bark of Trewia nudiflora. Their structures were elucidated by means of I D, 2 D NMR and HR-MS analyses. The antioxidant activities of these compounds were evaluated with the DPPH radical-scavenging assay. Compound 1 showed significant antioxidant activity. In addition, compounds 1, 2 and 3 rescued the H2O2-induced PC12 cell death at 0.4 mu M in the MTT assay.
