摘要
Phytochemical re-investigation of Coleus xanthanthus led to the isolation andidentification of a novel sesquiterpenoid 1, named as 4,5,1 1-trimethyl-8,9-seco-1(10),7(11) eremophiladien-8,12-olid-9-cio acid. The structure of 1 was elucidated by modern spectroscopicmethods, especially by X-ray diffraction.
