Abstract
A new guaiane sesquiterpene, 3α,9α-dihydroxy-11βH-guai-4(15),10(1)-dien-12,6β-lactone, along with five known compounds were isolated from the whole plants of Paraixeris pinnatipartita. Their structures were identified on the basis of spectroscopic methods, including IR, EI-MS, HR-ESI-MS, 1D NMR and 2D NMR.
