Abstract

Ultrasound-assisted extraction (UAE) of polysaccharides from mulberry leaves was studied. The effects of four factors on the yield of polysaccharides were investigated. The results showed that optimum conditions were extraction power of 60W, extraction temperature of 60°C, extraction time of 20min and ratio of water to raw material of 15:1 (ml/g). The three different methods (UAE, MAE and CSE) were compared for extracting polysaccharides from the mulberry leaves by SEM images. Totally, UAE had the largest yield of polysaccharides. The crude polysaccharides obtained from UAE were purified and two components (MPS-1 and MPS-2) were obtained. Their structure was analysed with chemical methods. From FT-IR, they were polysaccharides. MPS-1 had more functional groups than MPS-2. From HP GPC analysis, molecular weights of MPS-1 and MPS-2 were 24898D and 61131D, respectively. From GC analysis, MPS-1 was composed of Sor, Ara, Xyl and Glc, and MPS-2 was composed of Rha, Ara, Xyl, Glc, Gal and Man.

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • UAE is a non-thermal technique in which sound waves cause cavitation that disrupts cell walls, reduces particle size and enhances solvent contact with target compounds.

    “UAE is a non-thermal extraction technique wherein sound waves migrating through a medium, inducing pressure variations and cavitations that grow and collapse, transforming the sound waves into mechanical energy, which disrupts the cell walls, reduce the particle size and enhance the contact between the solvents and the targeted compounds”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
