Abstract EN
Ultrasound was used for the extraction of larch arabinogalactan from Larix gmelinii.
The optimal conditions for ultrasound extraction were determined by response surface methodology.
Specifically, the Box-Behnken design was employed to evaluate the effects of three independent variables: ultrasound time, temperature, and liquid-solid ratio.
The highest arabinogalactan yield (11.18%) was obtained under the optimal extraction condition (extraction temperature 41.5°C, extraction time 24.3 min, and liquid-solid ratio 40 mL/g).
In addition, the antioxidant activity of arabinogalactan that was extracted from dihydroquercetin extraction residues exhibited a moderate and concentration-dependent hydroxyl radical-scavenging capacity, ferric-reducing power, and reducing power.
The wood material was characterized before and after processing by scanning electron microscopy and Fourier-transform infrared spectroscopy.
