Two new cyclized C ‐geranylated flavonoids, the dihydroflavonol bonanniol C ( 4a ) and the flavanone bonannione B ( 6a ), were isolated as minor compounds from the aerial parts of Bonannia graeca (Umbelliferae). Their structures were elucidated by a combined approach of extensive spectroscopic means and quantum mechanical methods. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2007)
