Popis: | From the seed-pods of Eperua purpurea (Leguminosae), several diterpenoids were isolated and their structures determined on the basis of spectroscopic evidence. A new clerodane-type diterpene whose structure we assign as (-)-cleroda-7,13E-dien-15-oic acid {2}, a known clerodane (-)-2-oxo-10α-cis-cleroda-3,13E-dien-15-oic acid {3}, and two known labdane compounds, (-)-7-oxolabda-8,13E-dien-15-oic acid {4} and copalic acid {5}, were obtained |
