“…Thus, ABP have relatively small molecular mass. Pharmacological and clinical studies have shown that ABP can exert antioxidant, antiallergic, immunomodulatory, arthritis alleviation, antiinflammatory, hepatoprotective, and anticancer effects ( Kim and Park, 2010 ; Bang et al., 2012 ; Jang et al., 2012 ). Previous studies have indicated that ABP have significant immune-stimulating activity, which are achieved through the generation of reactive oxygen species, the secretion of cytokines, cell proliferation, and the phagocytic activity of macrophages ( Li and Li, 1997 ; Yin et al., 2019 ; Zhang et al., 2019 ).…”

This study was conducted to evaluate the effects of Achyranthes bidentata polysaccharide ( ABP ) on growth performance, antioxidant capacity, immune function, relative organ weight, ileal microflora, and meat quality in Pekin ducks. A total of 1,200 female 1-day-old Pekin ducklings (51.2 ± 0.2 g) were blocked based on body weight ( BW ) and randomly allocated into 3 treatments with 10 replicates of 40 birds each. The experiment lasted for 6 wk, and dietary treatments included corn–soybean meal–based diet supplemented with 0, 0.02, and 0.04% ABP. The supplementation of ABP increased ( P < 0.05) body weight gain ( BWG ) and final BW linearly during day 22 to 42 and day 1 to 42, respectively, but decreased ( P < 0.05) feed-to-gain ratio ( F/G ) linearly during day 22 to 42 and day 1 to 42. The inclusion of ABP increased ( P < 0.05) serum superoxide dismutase, glutathione peroxidase, total antioxidative capacity, catalase, complement3, complement4, immunoglobin A, immunoglobin G, interleukin-2, interferon-γ, and tumor necrosis factor-α linearly. The relative weight of breast meat was increased ( P < 0.05) linearly, but the relative weight of abdominal fat was decreased ( P < 0.05) linearly with the increasing dietary ABP supplementation. The supplementation of ABP increased ( P < 0.05) ileal Lactobacilli counts linearly, whereas decreased ( P < 0.05) Escherichia coli counts linearly. Taken together, the inclusion of ABP promoted BWG and final BW during day 22 to 42 and the entire experiment, decreased F/G during day 22 to 42 and day 1 to 42, and partially improved antioxidant activities, immunity, and gut microflora in Pekin ducks.

“…The methods used for the extraction of plant polyphenols mainly include organic solvent extraction, ultrasound-assisted extraction, microwave-assisted extraction and enzymatic extraction [14,15]. After extraction, processes of separation and purification are necessary if the phenolics need to be further purified.…”

An efficient preparative separation method for Sphallerocarpus gracilis stems and leaves polyphenols (SGslP) was established in this study. An X-5 macroporous adsorption resin was selected for the purification of the SGslP, and the polyphenol content of the purified SGslP (PSGslP) was increased 5.11-fold from 8.29% to 42.38% after one treatment run. The chemical composition of the PSGslP was analyzed by HPLC-MS/MS, and the predominant compounds were found to be luteolin-7-glucoside, acacetin-7-acetyglycoside and its isomers. In addition, the PSGslP was evaluated in vitro to determine the DNA damage-protective activity and inhibitory effects of α-amylase and α-glucosidase. The results indicated that the PSGslP exhibited significant protective activities against both ROO‚ and ‚OH radical-induced DNA damage. Moreover, the PSGslP exerted a dose-dependent inhibition effect on α-glucosidase but no inhibitory effect on α-amylase. These findings indicate that the Sphallerocarpus gracilis stems and leaves are good natural sources of antioxidants and are potent inhibitors of α-glucosidase activity and are potential anti-diabetic inhibitor.

: The Ponciri fructus immaturus (Poncirus trifoliata Rafinesque) has been used in oriental medicine for uterine contraction, stomachache, abdominal distension and cardiovascular diseases. Two main compounds, poncirin and naringin were successfully analyzed by high performance liquid chromatography (HPLC) and carried out method validation according to ICH guideline. A successful resolution and retention times were obtained with a C 18 reversed phase column, at an 1 ㎖ min −1 flow rate, with a gradient elution of a mixture of methanol, water and acetonitrile. Poncirin and naringin showed good linearity (R 2 > 0.999) in relatively wide concentration ranged. The recovery of each compound was 95.81~101.48% with R.S.D. values less than 1.0%. The application of ultrasound-assisted extraction was shown to be more efficient in extracting poncirin and naringin from Ponciri fructus immaturus. The predicted optimal poncirin and naringin yield were poncirin 2.15%, naringin 1.65% under an extraction temperature of 40℃, an extraction time of 10 min in a solvent of 70% methanol.
