Ultrasound-microwave synergistic extraction enhances bioactivities of Phyllanthus emblica L. polysaccharides through structure-function modulation.

ABSTRACT: Phyllanthus emblica L. is a traditional medicinal and edible plant, and its primary bioactive constituents are polysaccharides. In this study, the Ultrasonic-Microwave synergistic extraction method (UMSE) was used to extract polysaccharides from Phyllanthus emblica L. (PEP) under optimized conditions: microwave power of 370 W, ultrasonic power of 340 W, a solid-liquid ratio of 1:6.5 (w/v), and a time of 25 min, resulting in an extraction yield of 8.05 % ± 0.12 %. After purification using DEAE-52 cellulose and Sephadex G-100, three polysaccharide fractions exhibiting distinct differences in molecular weight named PEP-A, PEP-B, and PEP-C were obtained. Structural characterization demonstrated that UMSE influenced the monosaccharide composition, spectral properties, surface morphology, and th
