| Abstract: | Several ent-13-epi-manoyl oxides and a new natural product, ent-8α-hydroxylabda-13(16),14-dien-19-oic acid, have been isolated from Sideritis varoi subsp. cuatrecasasii. In addition, a study has been made of some natural and semisynthetic ent-13-epi-manoyl oxides functionalized at C-12. |
