摘要
Two new furanoeremophilanes, 1 alpha, 6 alpha-epoxy-9-oxo-10 beta-hydroxyl-furanoeremophilane (1), and 9-oxo-1 alpha, 6 beta, 10 beta-trihydroxy-furanoeremophilane (2) were isolated from Senecio nemorensis. Their structures were elucidated by spectroscopic methods and X-ray crystallography. This is the first report of the isolation of the C1-C6 oxygen bridge of furanoeremophilane. Their cytotoxic effects on BEL7402 and NF-KB cell lines were tested.
