New Sesquiterpenes from Cacalia ainsliaeflora
Two new eremophilane sesquiterpenes, 3β-angeloyloxy-8-oxo-eremophil-6(7)-en-12- oic acid 1 and 3β-angeloyloxy-10β-hydroxy-8-oxo-eremophil-6 (7)-en-12-oic acid 2, and a novel nor-eremophilane derivative, 3β-angeloyloxy-10β-hydroxy-8-oxo-eremophil-6(7)-en 3 were iso-lated from the roots of Cacalia ainsliaeflora. Their structures were elucidated by spectroscopic methods, including 2D NMR.
