摘要
Two new eremophilane sesquiterpenes 3β-angeloyloxy-8α-hydroxy-6β-methoxy eremophil-7 (11), 9 (10)-dien-8, 12-olide (1) and 3β-angeloyloxy-6β, 8α-dihydroxy-eremophi-7 (11), 9 (10)-dien-8, 12-olide (2) were isolated from Cacalia ainsliaeflora. Their structures were established by spectroscopic methods and 2D NMR experiments.
