New 3-Methyoxyflavones, an Iridoid Lactone and a Flavonol from Duroia hirsuta
Investigation of the roots of Duroia hirsuta from Ecuador yielded the iridoid lactone duroin (1) together with 3,7,3‘,5‘-tetramethoxy-4‘-hydroxyflavone (2), 3,7,3‘-trimethoxy-4‘,5‘-dihydroxyflavone (3), and 7,3‘,5‘-trimethoxy-3,4‘-dihydroxyflavone (4) as novel constituents.
