Terpenoids and Unusual Flavonoids Bearing Prenylated Malonic Acids in Dodonaea Species

Abstract

AbstractNatural products isolation studies were performed on two Dodonaea species. This led to the discovery of one previously unreported prenylated flavonoid bearing a malonic acid moiety and six known compounds from the aerial parts of Dodonaea filiformis. In addition, three previously unreported natural products (another malonic‐acid‐containing prenylated flavonoid, a prenylated flavonoid and an ent‐labdane diterpenoid) and seven known compounds were found from the flowers of D. viscosa. Furthermore, as a result of this work, a revised structure is proposed for a prenylated flavonoid previously isolated from D. viscosa.
