Constituents of Ipomoea horrida Humber ex ducke: spectroscopic identification of the flavonoids

Abstracts

As part of a systematic investigation of the Ipomoea species of Northeastern Brazil, a mixture of 7,4'-diO-methylkaempferol and 7,3',4'-tri-Omethylquercetin were identified in extracts obtained from the aerial parts of Ipomoea horrida.
