Analysis of distribution of wood extractives in Gmelina arborea by gas chromatography and time-of-flight secondary ion mass spectrometry
The aim of the present study was to investigate the extractives of stem from the sapwood (sW) to heartwood (hW) including the transition zone (tZ) between them by means of quantitative GC-MS, while the spatial distribution of four typical compounds was analysed by TOF-SIMS. The focus was on gmelinol...

Summary: | The aim of the present study was to investigate the extractives of
stem from the sapwood (sW) to heartwood (hW) including the transition zone (tZ) between them by means of quantitative GC-MS, while the spatial distribution of four typical compounds was analysed by TOF-SIMS. The focus was on gmelinol, paulownin, 7′-
-ethyl arboreol, and β-sitosterol, which were isolated and purified from hW. The four compounds revealed a characteristic distribution pattern corresponding to their key role in biosynthesis and depending on their susceptibility to secondary reactions in the hW. |
