Optimization of arabinogalactan and taxifolin extraction process from Dahurian larch (Larix gmelinii ) and evaluation of the effects on activities of α-amylase, α-glycosidase, and pancreatic lipase in vitro

Double experimental designs, Plackett–Burman design coupled with Box–Behnken design, were used to optimize the simultaneous extraction process of arabinogalactan and taxifolin from Larix gmelinii by ultrasonic microwave synergistic extraction (UMSE) method. The optimal extraction conditions were determined with the extraction yields of 223.40 ± 7.82 mg/g for larch arabinogalactan and 125.02 ± 5.30 mg/g for taxifolin. Compared to conventional...
