Abstract
Representatives of the genera Odixia and Ozothamnus, Australian Astera ceae belonging to the tribe Gnaphalieae, have been analyzed for the pr esence of flavonoid aglycones accumulated on leaf and stem surfaces. F iftytwo more or less lipophilic flavonoids have been identified. Methy l ethers of apigenin, luteolin, kaempferol and quercetin are abundant, while rare methyl ethers of isoscutellarein, 8-hydroxy galangin, herb acetin and gossypetin appear to be characteristic. The distribution of rare flavonoids is discussed.
