Microwave assisted (MW) and autohydrolysis (AH) extraction processing were the two green technologies compared in this study to recover bioactive compounds. Fresh crushed branches were placed in each extraction device using distilled water as a solvent at the following operation conditions: liquid: solid ratio fixed at 15:1 (w/w) and a wide range of extraction temperatures (140, 160, 180, 200, and 220 °C) was used. In the case of AH treatment, distilled water and ground sample were processed in a stirred pressure reactor (Parr instruments series 4842, Il., USA) of 0.6 L volume equipped with temperature controller and heater. The same conditions as the autohydrolysis were reproduced in a Microwave reactor (Anton Paar, Monowave 450, Austria) in order to obtain comparative severity factor (log Ro), i.e. the treatment efficiency, according to Overend and Chornet (1987) .
The obtained liquid phases were filtrated and separated from the solid phases. The liquors were further analysed to determine their bioactive potential. Solid phases were set aside (−20 °C) for future potential agricultural applications as adsorbent or fertilizer.
