The new diterpenes dehydroabietan-18-ol acetate, teideadiol 18-monoacetate, teideadiol 18-malonate and teidic acid have been isolated from the aerial parts of Nepeta teydea. The known diterpenes dehydroabietan-18-ol (pomiferin A) and teideadiol have also been obtained from this species. The (13)CNMR spectra of several dehydroabietane derivatives have been assigned.

Lophachinins A–E, abietane diterpenes from a Mongolian traditional herbal medicine Lophanthus chinensis
Five new abietanediterpenes, lophachinins A–E (1–5), and eleven known related diterpenes were isolated from a Mongolian traditional herbal medicine, the aerial parts of Lophanthus chinensis (Lamiaceae). The structures of new diterpenes were assigned by spectroscopic analyses. Lophachinins A (1) and B (2) were abietanediterpene possessing an endoperoxy bridge at C-ring. In contrast, lophachinins C–E
