New constituents of the leaf and stem exudate of Ozothamnus hookeri (Asteraceae).
The exudate of Ozothamnus hookeri has been investigated for its non-flavonoid constituents. A new natural C6-C3 ester of a long chain fatty acid and seven structurally related kaurane-diterpenoids were isolated. Three of the latter are new natural products, too. A rare 8-methoxy flavonol was also identified.
