The isolation from Trachylobium verrucosum of seven new bicarbocyclic diterpenes, possessing the (−) labdane skeleton, is described. Their structure have been determined as 4d, 6d, 6e, 6f, 7a, 8a and 10b. In addition, caryophyllene oxide (9), enantio labd-8(20), 13-diene-15 oic acid (4g), enantio labd-8(20)-en-15,18-dioic acid (6c), enantio labd-8(20)-en-15-oic acid (5b) and (−) 13-epimanool (10a)
