Terpenoids and phenylethyl esters from the exudate of the Australian plant Ozothamnus ledifolius (Asteraceae)

摘要

The leaf exudate of Ozothamnus ledifolius, previously reported to contain a series of flavonoid aglycones, mostly consists of a mixture of terpenoids. From this resinous material we now identified four sesquiterpenes, a diterpenediol and two pentacyclic triterpene acids. In the phenolic portion we found three phenylethyl esters. [References: 21]
