Extractable Compounds in a Birch Tree—Variations in Composition and Yield Potentials

Extractives from silver birch (Betula pendula) can play an important role in the future bioeconomy by delivering feedstock, for instance, antioxidative applications. It is, therefore, inevitable to gain knowledge of distribution extractive content and composition different tissues tree estimating potential volumes valuable extractable compounds. This study examines compound such as outer inner bark wood, respectively, considering original height stem comparing yields after Soxhlet accelerated solvent extraction (ASE). Eleven parts model (seven discs four branches) were separated into primary extracted with a ternary system. The investigated methods resulted comparable performance regarding extractives. extractives divided single compounds betulin, lupeol, γ-sitosterol, lupeone substance groups carbohydrates, terpenes, aromatics, other groups. substances depends on location function examined tissues. Furthermore, evidence correlation substance’s is stronger lupeol than betulin. Primary betulin sources calculated output are branches. By using small branches, further be utilized. A calculation current revealed significant 23 kg available chemical resource by-product utilization.
