摘要：

A new oxa-cage natural product daphniacetal A (1) was isolated from Daphniphyllum macropodum Miq. Its structure and relative configuration were established based on spectroscopic data and the single-crystal X-ray diffraction crystallography. Compound 1 was also synthesized for determination of its absolute configuration and evaluation of antioxidant effects. (C) 2008 Elsevier Ltd. All rights reserved.
