“…The reduction in the pectin yield with the augment of solvent amount is not in agreement with mass transfer principles, since the concentration gradient which is the driving force is thought to be higher when a lesser solid to solvent ratio is used. Similar effect was observed for the extraction of polysaccharides from Acanthopanax senticosus [18] and Boletus edulis mycelia [19].…”

Four factors three level face centered central composite response surface design was employed in this study to investigate and optimize the effect of process variables (liquid-solid (LS) ratio (10:1-20:1ml/g), pH (1-2), sonication time (15-30min) and extraction temperature (50-70°C)) on the maximum extraction yield of pectin from waste Artocarpus heterophyllus (Jackfruit) peel by ultrasound assisted extraction method. Numerical optimization method was adapted in this study and the following optimal condition was obtained as follows: Liquid-solid ratio of 15:1ml/g, pH of 1.6, sonication time of 24min and temperature of 60°C. The optimal condition was validated through experiments and the observed value was interrelated with predicted value.

“…Most studies have paid much attention on the active constituents and pharmacological properties of F. velutipes. Polysaccharides, one of the most important components of mushrooms, have exhibited extensive and powerful benefits applicable in developing novel drugs and functional foods, which are correlated to their immune-modulating, anti-oxidation, anti-tumor and nontoxic effects (He et al, 2016;Hou et al, 2013;Sang, Yong, Sang, & Jin, 2015;Zhang, Cui, Cheung, & Wang, 2007;Zhao, Xu, Ye, & Dong, 2013). Several polysaccharides have been isolated from F. velutipes fruiting bodies or mycelia, and their anti-oxidation, anti-tumor and immuno-regulatory effects were studied (Ikekawa et al, 1982;Miao, Wang, & Wu, 2003;Wu & Gao, 2002;Wu, Duan, Liu, & Cen, 2010;Yang, Fang, Liang, & Hu, 2011;Zhao, Dong, Chen, & Hu, 2010).…”

The optimal conditions for preparing Zn-Flammulina velutipes polysaccharide (Zn-FVP) chelate were studied by using L 9 (3 4) orthogonal test. The results showed that the optimized conditions for the chelating reaction were as follows: initial concentration of Zn (II), 6 mg/mL; ratio of purified polysaccharide (FVPp) to Zn (II), 1:2; chelating time, 8 h; and pH, 5. Chelating rate achieved 98.11% under the optimal conditions. Characteristic bands for OH stretching at 3000-3500 cm −1 and bands corresponding to C-H variable angle vibration between 1000-1100 cm −1 showed some obvious differences for chelation of polysaccharides and zinc. The qualitative spectrum of Zn-FVP indicated the presence of ZnSO 4 and the abundant Zn (II) groups were widely present in the chelated samples. The anti-inflammatory effect of FVPp and Zn-FVP on Lipopolysaccharide-stimulated RAW 264.7 cells was evaluated. In the range of 5-50 μg/mL, Zn-FVP did not exhibit obvious inhibition of the survival rate of cells. Zn-FVP in noncytotoxic levels showed strong suppressive effect on the inflammatory cytokines (IL-6, TNF-α, INF-γ and NO) and these provided a theoretical base for the anti-inflammatory mechanism of Zn-FVP.

“…This might be due to the degradation of heat sensitive bioactive compounds and the possibility of solvent vaporization (Brijesh, 2015). cate that the yield of TPC and TFC increases with time initially and gradually reaches its maximum at 20 min (Zhao, Xu, Ye, & Dong, 2013). It is also found that there is a prompt increase of extraction at the initial stages and a slower rate of extraction at the end.…”

The aim of the present study is to optimize the ultrasonic-assisted solvent extraction (UASE) variables and to identify the phytochemical compounds present in the prickly pear (Opuntia ficus-indica) peel extract and the results are compared with the extract obtained using soxhlet extraction (SE) techniques. Box-Behnken design (BBD) was used to optimize the UASE variables and the maximum TPC (5.95 mg GAE/g dW) and TFC (9.79 mg RUE/g dW) was obtained at 17 min of time, 40 C bath temperature and 1:24 g/mL solid-solvent ratio. The SEM analysis further shows that ultrasonic cavitation caused morphological changes, which accelerates the rate of extraction. The phytochemical analysis of UASE and soxhlet extracts revealed that the components which possess pharmacological activity are about 68.08% in UASE, whereas 61.72% in SE. In addition, components like phytol, azulene, andrographolide, serverogenin acetate, and stigmasterol, possess pharmacological properties that are notably present in UASE and are absent in SE.
