摘要：

Eupatorium buniifolium was investigated for diterpenoid content. Methyl-ent-labd-8(17)-en-18-oic acid-15-oate, 15-hydroxy-ent-labd-8(17)-en-18-oic acid, 15,16-epoxy-15-methoxy-ent-labd-8(17)-en-18-oic acid and 15-methoxy-ent-labd-8(17)-13-dien-18-oic acid methyl ester-16,15-olide were isolated from the aerial part of this plant and their structures were determined. The known compounds polyalthic acid and nivenolide were also identified. All these compounds were characterized on the basis of spectral analysis (including 2D NMR) and physical constants.
