Of the above four types, cadinanes are most common and are fairly widely distributed in nature (396). Several of these compounds have been found in woody parts of plants. Examples are T cadinol (294) and the hydroxy ketone 295 from the wood of Taiwania cryptomerioides (92, 255), (4-)-5-cadinene (296) from trunk wood of Cedrela toona (291), and (-)-y-cadinene (286), khusinol (297) and several related compounds from vetiver oil of North Indian origin (222, 394). Muurolenes (e.g., e-muurolene, 298) were first characterized in 1966, and were isolated from wood of Firms sylvestris (413). Cedrela toona wood (291). The other two types have not...
