spectrum. There are some additional signals in the aliphatic and aromatic region, but of very weak intensity aswas confirmed by the analysis of 2D spectra and DEPT-135. The chemical shift difference between literature data (Jansson et al., 2006) and our signals,1.8 ppm for 13C (Table 3), (Lundborg & Widmalm, 2011), is a consequence of the internal reference standard we used (Section 2.9.2).
