Barking up the right tree : The spirodienone sesquineolignan pinobatol ( 1 ), a long‐time speculated monomeric unit of lignin, was isolated from the 70 % aqueous acetone extract of pine ( Pinus sylvestris L.) bark. Its structure was determined by high‐resolution electron ionization mass spectrometry and a variety of NMR spectroscopic techniques.
