Received Date: 27 February 2001

Fund Project: The authors wish to thank all members of the analytical group of Phytochemistry Laboratory of Kunming Institute of Botany, Academic Sinica, for the measurement of spectral data.

A new 6,7-seco-ent-kaurane diterpenoid, together with two known ones, was isolated from the leaves of Isodon eriocalyx var. laxiflora C. Y. Wu & H. W. Li. Their structures were established by spectroscopic methods.
