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.
基金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.
