The absolute configurations of angelols A-H (1-8) isolated from Angelica pubescens MAXIM. (Umbelliferae) were determined to be as shown in Chart 1 by means of chemical, spectral and X-ray analysis. Furthermore, the stereostructure of angelol B (2) was determined to be as shown in Fig. 1 on the basis of X-ray analysis.
