摘要：

From the aerial parts of Teucrium pestalozzae two new neo-clerodane diterpenoids, teupestalins A and B, have been isolated. The structures of teupestalin A (4α,18;15,16-diepoxy-6β,10β-dihydroxy-neo-cleroda-13(16) ,14-dien-20, 12S-olide-3α,19-hemiacetal) and teupestalin B (19-acetoxy-4α,18;15,16-diepoxy-6-oxo-neo-cleroda-13(16),14-dien-2 0, 12S-olide-3β,10{circled dash}hemiacetal) were established by spectroscopic means and, in the case of teupestalin A, also by an X-ray diffraction analysis. Teupestalins A and B are the first C-10 oxygenated neo-clerodane derivatives found in plants belonging to the genus Teucrium. © 1990.
