A comparison of the Björkmann lignins from larch and fir woods


To decide this question, ervinidine was reduced with sodium borohydride in methanol. This gave an amorphous base, ervinidinol, with R] 0.43 [thin-layer chromatogram on silica gel, ethylacetate-methanol (9 : 1)], and 0.89 [paper chromatogram, bu t an l -o l acetic ac id water(100: 5: 100) ]. The UV spectrum of ervinidinol had one maximum: ?'max 288 mg (log s 3.44) and a small break at 254 m/~ (log 8 3.60) characteristic for an indole derivative.
