Simultaneous Microwave-Ultrasound Assisted Extraction of Bioactive Compounds from Bark

Larix decidua is one of the fastest growing conifers and one of the most important coniferous tree species in Europe with high importance at wood-based industry; however, the bark generated from the debarking process is mainly considered as waste. This study aimed to evaluate the chemical compositio...
