Figure 2

FT-Raman spectra collected from two distinct bark points from each of nine birch trees from spontaneous forest flora area in the Apuseni Mountains, Romania. The relative intensity of the bands at 1633 cm-1 representative for the triterpenes and 1601 cm-1 assigned to other species than triterpenes, I1633/I 1601 varies from 0.9 to 1.1 in the nine bark samples.
