One new and six known lignans, as well as sideritoflavone and rosmarin
ic acid were isolated from Hyptis verticillata. The new lignan, hyptin
in, was fully characterized by spectroscopic methods (UV, H-1, C-13 NM
R, MS, IR, CD). The known lignans were identified as dehydropodophyllo
toxin, dehydrodesoxypodophyllotoxin, 4'-demethyldesoxypodophyllotoxin,
podophyllotoxin, podorhizol and epipodorhizol.
