Vsebnost ekstraktivov v skorji in lesu robinije (Robinia pseudoacacia L.)

Vsebnost ekstraktivov v skorji in lesu robinije (Robinia pseudoacacia L.)

The content and composition of extractives in the wood and bark tissue of black locust (Robinia pseudoacacia L.) were investigated. Wood and bark samples were extracted using a Soxhlet apparatus with acetone. The extracts were gravimetrically examined to measure total hydrophilic extractive...
