Abstract
Eupatorium buniifolium was investigated for diterpenoid content. Methy l-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 w ere also identified. All these compounds were characterized on the bas is of spectral analysis (including 2D NMR) and physical constants.
