Structural determination of diterpenes from Daphne genkwa by NMR spectroscopy

Abstract Five daphnane type diterpenes have been isolated from the chloroform soluble fraction of Daphne genkwa. The structure of the new compound (1) was assigned as 5β‐hydroxyresiniferonol‐6α,7α‐epoxy‐12β‐acetoxy‐9,13,14‐ ortho ‐2 E ‐decenoate by extensive NMR studies. Copyright © 2006 John Wiley & Sons, Ltd.
