Seven new carolignans, including two pairs of enantiomers (±)-erythro-7'-methylcarolignan E (1a/1b) and (±)-threo-7'-methylcarolignan E (2a/2b), (+)-threo-carolignan E (3a), (+)-erythro-carolignan E (4a), and (-)-erythro-carolignan Z (5), together with four known lignans (3b, 4b, 6, and 7) and six polyphenols (8-13) were isolated from the aerial parts of Euphorbia sikkimensis. The structures of the new compounds were elucidated by spectroscopic analysis, and their absolute configurations were de ...[more]
