A new flavanone from Teucrium alyssifolium

Abstract

From the aerial parts of Teucrium alyssifolium in addition to previously obtained neo-clerodane diterpenoids, a new flavanone alysifolinone and three flavones cirsiliol, cirsilineol and luteolin-6, 7, 3', 4'-tetramethyl ether, were isolated. The structure of the compounds was established by spectral data, and by TLC comparison for the known compounds.
