 Title    New Cembranoids from Burley T ob acco  
 Abstract    The liquid C 0 2-extract of aged burley tobacco was investigated for its content of diterpenoids, which are considered as im portant precursors of flavour constituents. Among several cembranoids, already known from various tobacco types, 4,8-dimethyl-8-hydroxy-l l-(l-methyl-ethyl)-14-oxo-pentadeca-5,9-diene-4-olide, a new natural product, could be identified, evidently originating from 2,6,11-cem-bratriene-4,8-diol by oxidative cleavage of the 11,12-double bond with subsequent cyclization to the seco-lactone 14.

 Title    Ozothamnus scutellifolius (A steraceae)  
 Abstract    Leaf and stem exudate of Ozothamnus scutellifolius, previously reported to contain 21 flavonoid aglycones, was now investigated for its terpenoid composition. Seven structurally related diterpenoids were identified. One of them, 16a,19-diacetoxy-enf-kaurane, is a novel natural product.
