“…Moreover, the low molecular weight fractions in CMP-U (73.72%) were higher than those of CMP-H (62.56%). This could be attributed to the degradation of CMPs caused by ultrasonic power, which was correspondent with previous literature [24,38].…”

In order to evaluate the antioxidant and α-glucosidase activities of polysaccharides from Chrysanthemum morifolium cv. Hangju (CMPs), the response surface methodology was applied to optimize the parameters for extraction progress of CMPs by ultrasound, with heat reflex extraction (HRE) performed as the control. The difference in the physicochemical properties of polysaccharides obtained by the two methods were also investigated. The maximum yields (8.29 ± 0.18%) of polysaccharides extracted by ultrasonic assisted extraction (UAE) were obtained under the optimized conditions of ultrasonic power 501 W, extraction time 19 min, and ratio of liquid-to-raw material 41 mL/g. Polysaccharides extracted by UAE possessed lower protein contents (2.56%) and higher uronic acids contents (7.08%) and low molecular weight fractions than that by HRE. No significant differences were found in monosaccharide composition and Fourier transform infrared (FT-IR) spectra of polysaccharides extracted by UAE and HRE, while polysaccharides by UAE possessed stronger antioxidant and α-glucosidase inhibitory activities. Therefore, UAE was an efficient way to obtain CMPs.

“…The FT‐IR spectrum of polysaccharides isolated from G. lucidum displayed absorption bands at 3,000–3,500 cm −1 (–OH stretching), 2,950 and 2,850 cm −1 (aliphatic C–H groups), 2,922 cm −1 (CH 2 stretching), 1635 cm −1 (proteins), 1,407 cm −1 (aliphatic groups), 1,032 cm −1 (α‐linkages), and 890 cm −1 (β‐glycosidic (C1–H) deformation) (Kozarski et al, ). FT‐IR spectra of four polysaccharides obtained from Poria cocos showed absorption bands at 3,388–3,392 cm −1 (–OH stretching), 2927–2931 cm −1 (C–H stretching and bending), 1,615–1,619 and 1,414–1,420 cm −1 (asymmetric and symmetric stretching of C=O), and 1,200–1,000 cm −1 (stretching vibrations of C–O side groups and the C–O–C glycosidic band vibration) (Wang et al, ). The obtained data is in full compliance with the previous studies on the characterization of the mushroom polysaccharides.…”

Chemical composition and structural characterization of polysaccharides of Fomes fomentarius (FF), Fuscoporia torulosa, Ganoderma adspersum, Ganoderma applanatum (GAP), Ganoderma lucidum, Phellinus igniarius, Pleurotus ostreatus (PO), and Porodaedalea pini (PP) tree mushrooms with antioxidant and anticholinesterase activities were determined in this research. Total carbohydrate contents of the polysaccharides were ranged between 65.06 ± 6.76 and 88.27 ± 5.15 µg/mg and total protein contents were ranged between 3.18 ± 0.72 and 6.56 ± 1.25 µg/mg. Galactose, glucose, and mannose were identified as major monosaccharides in all polysaccharides using gas chromatography‐mass spectrometry. FT‐IR analysis showed the characteristic peaks of the polysaccharides and high performance liquid chromatography‐diode array detection was used to determine the molecular weight of the polysaccharides. In β‐carotene–linoleic acid assay FF (IC50: 2.55 ± 0.40 µg/ml) displayed the highest antioxidant activity, whereas GAP indicated the highest antioxidant activity in cupric reducing antioxidant capacity (A0.50:59.90 ± 0.53 μg/ml), ABTS•+ (IC50: 16.62 ± 0.31 μg/ml), and DPPH• (IC50: 45.58 ± 0.21 μg/ml) assays. In cholinesterase inhibitory activity test, PO (56.31±0.0.74%) showed significant inhibitory activity against butyrylcholinesterase enzyme. Practical applications Polysaccharides from mushrooms are the major class of bioactive compounds with various biological activities. Several studies were performed on the biological activity of the polysaccharide extracts from different mushrooms. However, to our knowledge, this is the first report on the chemical composition, structural characterization, antioxidant, and anticholinesterase activities of extracted polysaccharides from studied mushrooms in detail. This investigation shows that polysaccharide extracts obtained from tree mushrooms show a significant bioactivity and these polysaccharides might be used as bioactive natural sources in the pharmaceutical, food, and cosmetic industries.

“…In addition, the absorptions at 1073-1071 cm −1 (Fig. 3) indicated a pyranose form of sugar (Wang et al, 2016). A weak absorption at 897 cm −1 was observed in spectra of the four polysaccharide fractions, suggesting that pyranoses existed in the β-configuration in TMP30, TMP60, TMP80, and TMP (Luo et al, 2011).…”

Abstract:An ultrasonic-assisted technique was employed to extract crude polysaccharide from Tricholoma matsutake fruiting bodies. Single-factor tests and orthogonal experimental design (L 9 (3 3 )) were used to obtain the optimal extraction conditions. Results showed that the optimal parameters were as follows: ultrasonic temperature, 40 °C; ultrasonic time, 50 min; water to raw material ratio, 25 ml/g; ultrasonic frequency, 45 kHz; and ultrasonic power, 100 W. Three novel T. matsutake polysaccharide (TMP) fractions (TMP30, TMP60, and TMP80) were isolated and purified from TMP by stepwise alcohol precipitation. Their preliminary structural features were determined by highperformance anion-exchange chromatography with pulsed-amperometric detection (HPAEC-PAD) and Fourier transform infrared spectrophotometer (FT-IR) analyses. Furthermore, their in vitro antioxidant activity was investigated in terms of a reducing power assay and the scavenging rates of 2,2-diphenyl-1-picrylhydrazyl (DPPH) and hydroxyl radicals. The order of the various fractions based on their antioxidant activity was TMP80>TMP>TMP60>TMP30. These findings suggested that novel polysaccharide fractions from T. matsutake, especially TMP80, could be promising active macromolecules for biomedical use.
