Resumo

Two new lignans (R-biar)-12-angeloyloxy-6,7,8,9-tetrahydro-1,2,3,13,14-pentamethoxy-7,8-dimethyl-7-dibenzo[a,c]cyclooctenol (1) and (R-biar)-12-benzoyloxy-6,7,8,9-tetrahydro-1,2,3,13,14-pentamethoxy-7,8-dimethyl-7-dibenzo[a,c]cyclooctenol (2) were isolated from the stems of Celastrus flagellaris Rupr. Their structures were elucidated on the basis of spectroscopic methods including HR-EI-MS, 1D and 2D NMR, HMQC, NOESY, and CD.
