Abstract: The investigation of the rhyzomes of Hedychiumyunnanense Gagnep.afforded two new labdane type diterpenoids named yunnancoronarin A(4),B(5),together with three known ones hedychenone(1),7-hydroxyl-hedychenone(2), and coronarin E(3). Their structures were determined by spectral methods. Oxidation of 4 with PCCgave dehydroyunnancoronarin A(6), which rearranged to 1 under the acidic condition.

Key words: Hedychium yunnanense, Yunnancoronarin A, Yunnancorinarin B, Diterpenoids, Antimeoplastic activity
