Abstract

The aerial parts of four Cleome species (Capparaceae) were investigated for their surface flavonoids. Ten methylated flavonoids were isolated and identified as 5,7,4'-trihydroxy-3-methoxyflavone (isokaempferide), 5,7,4'-trihydroxy-3,3'-dimethyoxyflavone, 5,7,4'-trihydroxy-6,3'-dimethoxyflavone (jaceosidin), 5,4'-dihydroxy-3,6,7-trimethoxyflavone (penduletin), 5,7,3',4'-tetrahydroxy-3,6-dimethoxyflavone (axillarin), 5,7,4'-trihydroxy-6,3',5'-trimethoxyflavone, 5,4'-dihydroxy-3,6,7,3'-tetramethoxyflavone (chrysosplenetin), 5,3'-dihydroxy-3,6,7,4',5'-pentamethoxyflavone, 5,4'-dihydroxy-3,6,7,8,3'-pentamethoxyflavone and 5-hydroxy-3,6,7,3',4',5'-hexamethoxyflavone.
