Abstract In this study, polyphenols were extracted with subcritical water (SWE) from lotus seed epicarp. Based on single factor experiments, the extraction parameters were optimized by response surface methodology (RSM). Lotus seed epicarp polyphenols (LSEP) were purified by column chromatography (AB-8 macroporous resin) and identified by HPLC-ESI-MS. The antiproliferation ability of LSEP was also investigated. The optimal extraction parameters for the polyphenols were the temperature of 160℃, t...

Abstract Bioactive compounds in cash crops can be obtained from horticulture, oil and medicinal crops sources. Conventional extraction methods have disadvantages such as low extraction rate, large solvent consumption, high energy consumption and long production cycle. Ultrasonic-assisted extraction is a novel, green and rapid developing technology, which is suitable for up scaling and improving the extraction efficiency of bioactive compounds. Ultrasound mainly acts by producing cavitation bubbl...

Abstract Subcritical water extraction (SWE), an environment-friendly technique, was applied to extract polyphenolics from sorghum bran. Extraction temperatures (°C), time (min), and solid-liquid ratio (mL/g) were investigated and optimized by Box-Behnken design. The optimized conditions for SWE was 144.5 °C of temperature, 21 min of time, and 35 mL/g of solid-liquid ratio, with a polyphenolics yield of 47.253 ± 0.375 mg GAE/g dw, which was in good agree with the predicted value. Comparing with h...

Abstract Natural antioxidants play a critical role in the promotion of good health for its prevention of oxidative stress. The main purpose of this study is to investigate the protective effects of radish leaves extract on the oxidative damage in human fetal lung fibroblast (MRC-5) cells. F2, a fraction of radish leaves extracts, which was fractionated by different polarity solvents and AB-8 macroporous resins column shows the best free radical scavenging ability, the highest total polyphenol co...

Abstract Ultrasonic-assisted extraction (UAE), using aqueous ethanol as the solvent, was firstly applied to extract polyphenolic compounds from red sorghum bran. In this study, ultrasonic time (min), ethanol concentration (%) and solvent to solid ratio (mL/g) were investigated and optimized using a Box-Behnken design. The optimized result for UAE was 21 min of ultrasonic time, 53% of ethanol concentration, and 52:1 mL/g of solvent to solid ratio, 49.743 mg GAE/g dw of yield of total polyphenolic...

ABSTRACTIn the present study, we investigated the structure and selected functional properties of zein protein as treated with subcritical water. The results showed that subcritical water treatment, with different time (20–120 min) and temperatures (110–170°C), increased the solubility, foam capacity, and foam stability of zein protein significantly (p < 0.05). Analyses of particle size analysis, differential scanning calorimetry, circular dichroism spectra, scanning electron microscopy, and ato...

Abstract Water-soluble polysaccharides were obtained from Cordyceps militaris ( C. militaris ) (CMP) by subcritical water extraction (SWE). Two polysaccharides fractions, CMP-W1 and CMP-S1, were isolated from CMP using DEAE-52 cellulose and Sephadex G-150 column chromatography. The structural characteristics of CMP-W1 and CMP-S1 were investigated. The results showed that the molecular weight of CMP-W1 and CMP-S1 are 3.66 × 105 Da and 4.60 × 105 Da, respectively, and both of them were heteropolys...

Abstract This study aimed to evaluate the protective effect of Lotus seedpod procyanidins (LSPCs) from extremely low frequency electromagnetic field (ELF-EMF) exposure (50 Hz, 8 mT, 28 days) and their protective mechanism against radiation damage. The results showed that LSPCs increased the organ index of mice and made the damaged blood-producing function and cytokine(INF-γ, TNF-α, IL-2, IL-6 and IL-10 in spleen) levels by ELF-EMF-irradiation recovered to normal appearance. And experimental resu...

Abstract The present study investigated the protective effects of lotus seedpod procyanidins (LSPCs) on extremely low frequency electromagnetic field (ELF-EMF)-induced neurotoxicity in primary cultured rat hippocampal neurons and the underlying molecular mechanism. The results of MTT, morphological observation, superoxide dismutase (SOD) and malondialdehyde (MDA) assays showed that compared with control, incubating neurons under ELF-EMF exposure significantly decreased cell viability and increas...

Abstract With the increasing use of electromagnetic technology, the effects of extremely low-frequency electromagnetic fields (ELF-EMF) on biological systems, central neurotransmitter systems, and human health have attracted extensive attention worldwide. In this study, lotus seedpod procyanidins (LSPCs) were evaluated for their protective effects on ELF-EMF induced oxidative stress injury in mice. Sixty male ICR mice were used for the experiment. The mice were randomly divided into five equal g...
