摘要：

Two new guaianolide-type sesquiterpenoids, 4 beta,9 beta-dihydroxy-1 alpha,5 alpha-H-guaia-6,10(14)-dien (1) and 4 beta,9 beta,10 alpha-trihydroxy-1 alpha,5 alpha-H-guaia-6-en (2), along with four known sesquiterpenoids (3a, 3b, 4 and 5), were isolated from Kadsura interior. Their structures and configurations were elucidated by spectroscopic methods including 2D-NMR and HR-MS techniques. Compounds 3a and 3b were obtained as a pair of enantiomers, and their structure and absolute configuration were established from their extensive NMR spectra and by single-crystal X-ray analysis.
