Abstract
CANARIC ACID (3,4-SECO-LUPANE DERIVATIVE) ISOLATED FROM PROPOLIS OF CEARÁ.Phytochemical investigation of a propolis sample from Alto Santo -Ceará, Brazil, allowed identification of triterpenes (lupeol, lupenone, germanicone, canaric acid) and flavonoids (quercetin, kaempferol and acacetin), which were identified by spectroscopic data (IR, MS, and NMR, including 2D techniques).This is the first report of canaric acid in propolis.Propolis extract and flavonoids showed antioxidant activity using a DPPH radical scavenging assay.
