摘要:
Three new neo-clerodane diterpenoids, teucrolivins D-F, have been isolated from the aerial parts of Teucrium oliverianum. Their structures, 3-beta,7-beta,19-triacetoxy-4-alpha,18;15,16-diepoxy-6-alpha-hydroxy-neo-cleroda-13(16),14-diene (teucrolivin D), 3-beta,19-diacetoxy-4-alpha,18;15,16-diepoxy-6-alpha-hydroxy-neo-cleroda-13(16),14-dien-7-one (teucrolivin E) and 6-alpha,19-diacetoxy-4-alpha,18-epoxy-3-oxo-13,14,15,16-tetranor-neo-clerodan-12,10-beta-olide (teucrolivin F), were established by spectroscopic means.
