“…Table 3 Pearson correlation coefficients between the physicochemical properties of jujube powder moles of polyphenols (Jeong et al, 2004). Phenolic compounds formed by non-enzymatic browning in AD also could increase the polyphenol content, because the polyphenol-determining method using the Folin-Ciocalteu reagent can response to phenolic compounds (Hong et al, 2011). Similar results of polyphenol content were observed from drying studies with tangerine epicarp and onion (Jeong et al, 2004;Kim et al, 2007).…”

Physical and chemical properties of jujube powder with different powder sizes prepared by different drying methods were determined, and correlations of the properties were statistically analyzed. Air-, vacuum-, and freeze-dried (AD, VD, and FD, respectively) jujube were milled and sieved to produce powders. Powder size, morphological characteristics, color, volatile profile, moisture sorption isotherm, water solubility, rehydration, total sugar content, and polyphenol content of the powder were determined. Hunter L, a, and b, degree of browning, and volatile profile varied depending on drying methods. Moisture sorption isotherms exhibited typical Type II sigmoidal shape. Polyphenol content was highest in AD powder (2.6±0.1 mg/g). Powder size, morphology, water solubility, and total sugar content were not different by different drying methods. Correlations identified among the properties indicate rehydration of the powder could be maximized by controlling particle size and water activity of the powder. Rehydration and powder size of AD, VD, and FD powder were significantly correlated (p <0.001) (R 2 = 0.92, 0.88, and 0.94, respectively). Property correlations determined could be useful in customizing properties of jujube powder and increasing commercial uses of the powder.

“…Bradford method was operated to quantify total protein and BSA was used as a standard for Bradford method at 595 nm [27]. Total polyphenols were determined by the Folin-Ciocalteu reagent method using gallic acid as a reference at 750 nm [28]. Each powder sample was blended with distilled water to make a 1.0% (w/v) solution (10 mg/mL) for 1 h using a nutator mixer (FinePCR, Gunpo-si, Republic of Korea) while homogenizing with a sonicator (Branson, MO, USA) by 1 min sonication and 5 min cooling on ice-cold water.…”

In this research, the potential anti-obesity efficacy of Lactobacillus rhamnosus BST-L.601 and its fermented product (named SPY) with mashed sweet potato paste were investigated using 3T3-L1 preadipocytes and high-fat diet (HD)-induced obese mice. SPY (0–0.5 mg/mL) dose-dependently and significantly reduced lipid accumulation and TG content and the expression of adipogenic markers (C/EBPα, PPAR-γ, and aP2) and fatty acid synthetic pathway proteins (ACC and FAS) in 3T3-L1 adipocytes, demonstrating that SPY suppresses adipocyte differentiation and lipogenesis. Oral administration of SPY (4 × 107 CFU/kg body weight) to HD-induced obese mice for 12 weeks significantly reduced the body and liver weight, the size of adipocytes, and the weight of epididymal, visceral, and subcutaneous fat tissues. SPY was more effective in decreasing body weight gain in HD mice than in treatment with BST-L.601 alone. Administration of SPY or BST-L.601 also reduced the serum level of total cholesterol and LDL cholesterol and leptin secretion at a similar level. These results revealed that both SPY and BST-L.601 effectively suppress HD-induced adipogenesis and lipogenesis, suggesting that these materials would be useful in the functional foods industry to ameliorate and/or prevent obesity.

“…Total polyphenol content was determined using Folin-Ciocalteu’s phenol reagent, as previously published ( Hong et al, 2011 ), with the amount of total polyphenol determined in tannic acid equivalents. Total flavonoid content was analyzed using the method described by Jia et al (1999) , with slight modification.…”

The rhizomes of Cnidium officinale Makino have been used as a traditional medicine for many purposes, however, use of its aerial parts is very limited. We investigated the antioxidant properties and protective effects of the aerial parts (leaves and stems) from C. officinale on H2O2-induced toxicity in SH-SY5Y neuroblastoma. C. officinale methanol extracts (70%) were sequentially fractionated using hexane (non-polar fraction, NF), ethyl acetate (intermediate polar fraction, IF), and water (polar fraction, PF). Total phenolics and flavonoids contents were highest in IF, followed by PF. IF also showed the strongest radical scavenging activities against 2,2-diphenyl-2-picrylhydrazyl and 2,2'-azinobis(3-ethylbenzothiazoline-6-sulfonic acid), as well as superoxide, with the half maximal inhibitory concentrations of 13.2, 23.2, and 12.8 μg/mL, respectively. Furthermore, all fractions significantly inhibited linoleic acid peroxidation induced by the Fenton reaction or by UV irradiation. Both PF and IF protected against H2O2-induced SH-SY5Y neuronal cell death by increasing the cell survival by 22.1∼47.7 and 35.9∼50.3% at concentrations of 25∼100 and 25∼400 μg/mL, respectively, whereas NF was toxic to the cells at these concentrations. IF also significantly decreased intracellular levels of reactive oxygen species by 7.72∼47.47% at a concentration of 25∼200 μg/mL. Our results indicate that compounds from the aerial parts of C. officinale have potent antioxidant activities, which may help rescue neuronal cells from oxidative stress-induced injury. Therefore, the aerial parts, as well as the rhizomes, of C. officinale may have medicinal applications.
