Microwave-assisted extraction of polysaccharides from Camptotheca acuminate (CAPs) was optimized by response surface methodol. The optimal parameters were as follows: microwave power, 600 W; liquid-solid ratio, 40:1 g/mL; extraction time, 14 min; and extraction temperature, 70 °C. Under these conditions, the yield of CAPs reached up to 8.61%. CAP-3, an acidic polysaccharide with a mol. weight of 121.34 kDa, was separated and purified from CAPs, which was only composed of glucose and mannose. CAP-3 exhibited strong antioxidant activity against DPPH (IC50: 0.78 mg/mL), hydroxyl radicals (IC50: 0.84 mg/mL) and also showed synergistic antioxidative effect with ascorbic acid in vitro. Meanwhile, CAP-3 could protect plasmid DNA from oxidative damage. Moreover, CAP-3 could improve immunomodulatory activity of RAW264.7 cells through promoting the phagocytosis and nitric oxide release. Therefore, CAP-3 had a strong potential in functional food, pharmaceuticals and cosmetics industries.

In order to explore snow chrysanthemum polysaccharides (SCPs) as functional food ingredients and natural antioxidants for industrial applications, both microwave-assisted extraction (MAE) and ultrasonic-assisted extraction (UAE) were firstly optimized for the extraction of SCPs. Furthermore, the effects of conventional hot water extraction, UAE, and MAE on the chem. structures and antioxidant activities of SCPs were investigated. The maximum extraction yields of SCPs extracted by UAE (4.13 ± 0.24%) and MAE (4.26 ± 0.21%) were achieved at the optimized extraction parameters as follows: ultrasound amplitude (68%) and microwave power (500 W), ultrasound extraction time (21 min) and microwave extraction time (6.5 min), and ratio of liquid to raw material (42.0 mL/g for UAE and 59.0 mL/g for MAE). In addition, different extraction methods significantly affected the contents of uronic acids, the mol. weights, the molar ratio of constituent monosaccharides, and the degree of esterification of SCPs. SCPs exhibited remarkable DPPH (IC50 = 1.702 mg/mL), ABTS (IC50 = 1.121 mg/mL), and nitric oxide (IC50 = 0.277 mg/mL) radical scavenging activities, as well as reducing power (= 80.17 ± 4.8μg Trolox/mg), which suggested that SCPs might be one of the major contributors toward the antioxidant activities of snow chrysanthemum tea. The high antioxidant activities (DPPH, IC50 = 0.693 mg/mL; ABTS, IC50 = 0.299 mg/mL; nitric oxide, IC50 = 0.105 mg/mL; and reducing power, 127.79 ± 2.57μg Trolox/mg) observed in SCP-M extracted by the MAE method might be partially attributed to its low mol. weight and high content of unmethylated galacturonic acids. Results suggested that the MAE method could be an efficient technique for the extraction of SCPs with high antioxidant activity, and SCPs could be further explored as natural antioxidants for industrial application.

This study investigated the effect of Lactobacillus fermentum fermentation treatment on the gastrointestinal digestion and fermentation in vitro of polysaccharides from longan pulp. Polysaccharide isolated from unfermented and fermented longan pulp named LP and LP-F, resp. The mol. weight of LP-F declined from 109.62 ± 10.66 kDa to 51.46 ± 6.26 kDa while that of LP declined from 221.63 ± 2.41 kDa to 69.68 ± 2.36 kDa with gastrointestinal digestion. At same time, the reducing sugars content of LP and LP-F were both increased significantly. In addition, after 48 h gut microbiota fermentation, there were more total short chain fatty acids and acetic acid, as well as more Enterococcus, Bifidobacterium, and Clostridium in LP-F fermentation culture than those in LP fermentation culture. Moreover, LP-F fermentation culture showed lower pH value and less residual carbohydrate percentage than that of LP. These results indicated that LP-F is easier than LP to be fermented by human gut microbiota.

Microwave assisted extraction (MAE) technol. was used to extract polysaccharides from Porphyra Haitanensis (PHP) with water. Polysaccharide yield was used as index to evaluate the extraction process. Effects of ratio of water to raw material (X1), microwave power (X2) and extraction time (X3) on polysaccharide yield were investigated. Based on single factor experiment, MAE process of PHP was optimized using response surface methodol. Chem. characterization of PHP was investigated based on anal. of chem. compositions, monosaccharide and thermal gravimetric. The antitumor activities of PHP in vivo and in vitro were evaluated. The results indicated that the optimal conditions for MAE of PHP were ratio of water to raw material 28.98(mL/g), microwave power 77.84 W and extraction time 14.14 min. MAE was a suitable and efficient technique for PHP extraction compared with traditional hot water extraction Anal. of chem. characterization showed that PHP contained 75.36 ± 1.48% of total carbohydrates, 24.63 ± 1.69% of uronic acid residue and no proteins with monosaccharides such as rhamnose, arabinose, xylose, mannose, glucose, and galactose in a molar ratio of 10.25:9.38:1:12.45:9.9:11.55. Thermal gravimetric anal. suggested that PHP was relatively stable below 170°C. PHP had obvious effect on inhibiting proliferation, inducing apoptosis of SGC-7901 tumor cells in vitro and antitumor effect on SGC-7901 tumor-bearing mice in vivo. The results suggested that PHP had the potential for clin. use in cancer prevention and treatment.

Longan polysaccharides are valuable compounds with many biol. activities. Lactobacillus fermentum was selected to ferment longan pulp and the polysaccharides from unfermented and fermented longan pulp (denoted as LP and LP-F, resp.) were isolated. Their physicochem., immunomodulatory and prebiotic activities were investigated. The results revealed that LP-F, the mol. weight of which was lower than that of LP, contained less neutral sugar, uronic acid and glucose but more arabinose, galactose, rhamnose and mannose. Compared with LP, LP-F had better solubility, lower apparent viscosity and particle size. LP-F exhibited stronger stimulation on macrophages secretion of NO and IL-6, as well as better proliferation of Leuconostoc mesenteroides and Lactobacillus casei. In summary, fermentation treatment could change the physicochem. properties and enhance the bioactivity of polysaccharides from longan pulp.

Trichoderma viride was utilized to ferment the defatted rice bran (DRB), and soluble dietary fiber was prepared before and after fermentation, named as B-SDF and F-SDF, resp. Optimum fermentation conditions for yield of F-SDF were determined using response surface methodol. (RSM). The yield of F-SDF was significantly increased from 10.5 (weight/weight, %) to 33.4 (weight/weight, %) under the optimal conditions (inoculum size = 10%, pH = 5.8 and time = 41 h). Fourier transform IR spectroscopy (FTIR) demonstrated that both B-SDF and F-SDF had typical characteristics of the IR spectrum of polysaccharides, and X-ray diffraction (XRD) revealed they were mainly substances of amorphous structure. In addition, F-SDF showed looser structure by SEM (SEM) anal., increased mol. weight by high-performance gel permeation chromatog. (HPGPC) anal., and more complex monosaccharide composition by high-performance anion exchange chromatog. (HPAEC) anal. Furthermore, functional properties anal. showed that F-SDF exhibited higher water-holding capacity (WHC), oil-holding capacity (OHC), water solubility (WS) and cholesterol absorption capacity (CAC) than B-SDF. In summary, the present study suggested that SDF from defatted rice bran obtained through Trichoderma viride fermentation has a higher potential to be used as a functional ingredient in foods.

In order to explore polysaccharides from loquat leaves (LLPs) as functional food ingredients for prevention and treatment of obesity and type 2 diabetes, the physicochem. characteristics, in vitro binding properties, and inhibitory effects on α-amylase and α-glucosidase of polysaccharides from the leaves of different loquat cultivars, including ‘Baiyu’, ‘Chuannong8’, ‘Yuanbao’, and ‘Dawuxing’, were investigated and compared. Results showed that the contents of total uronic acids and degree of esterification in LLPs ranged from (27.04 ± 1.76)% to (41.46 ± 1.91)%, and from (20.54 ± 0.11)% to (26.90 ± 0.10)%, resp. The weight-average mol. weights of LLPs ranged from 4.307 × 106 Da to 5.101 × 106 Da, and the major constituent monosaccharides of LLPs were rhamnose, galacturonic acid, arabinose, and galactose. Furthermore, LLPs exerted strong in vitro fat binding, cholesterol binding, and bile acid binding capacities, as well as remarkable inhibitory effects on α-amylase and α-glucosidase, which might be attributed to their mol. weights, mol. weight distributions, and degree of esterification. Results are helpful for better understanding of chem. structures and bioactivities of polysaccharides from loquat leaves, and LLPs had good potential to be explored as functional food ingredients for prevention and treatment of obesity and type 2 diabetes.

Potato peel was used for the extraction of three types of polysaccharides (PW, PAL, and PAC) using water, alk., and acid treatments, resp. The structure of the PP polysaccharides was examined by means of Fourier transform IR spectroscopy (FT-IR) anal. and Gas chromatog.-mass spectrometry (GC-MS). The results suggest that the extracted polysaccharides constituted essentially three functional groups: C=O, C-H, and O-H. The polysaccharides were comprised of low proportions of proteins, 17-23% uronic acids, and approx. 70% carbohydrates. PAL, PW, and PAC with mol. weights of 2.25 × 103, 2.18 × 103, and 1.92 × 103 kDa, resp., were composed of rhamnose, xylose, mannose, arabinose, glucose, and galactose. Functional properties (solubility, oil holding capacity, foaming, and emulsion properties) of these polysaccharides were evaluated. Among three, PAL showed the highest fat-binding capacity which was 7.50 g/g with the solubility of 95.06%. The three polysaccharides possessed appreciable in vitro anti-oxidant (scavenging DPPH and ABTS+ radicals, chelating ferrous ions, and reducing power) potential. PAL exhibited the strongest reducing power, scavenging activity on DPPH radicals and chelating capability on ferrous ions. PP polysaccharides can be used as promising natural antioxidants in food, pharmaceutical, and cosmetic preparations
