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)
描述了七种新的具有(-)拉丹烷骨架的双碳环二萜与拟南芥的分离。已经确定它们的结构为4d,6d,6e,6f,7a,8a和10b。另外,石竹烯氧化物(9),对映LABD -8(20),13-二烯-15 OIC酸(4克),对映LABD -8(20) -烯-15,18-二酸(图6c),对映体labd -8(20)-en -15-油酸(5b)和(-)13-Epimanool(10a)已被分离。该树脂的成分与从该树的种子荚中提取的成分明显不同。后者主要包含与(-)贝壳杉烯有关的四碳环和五碳环的二萜。
