To study the physicochemical properties and antioxidant activity of ethanol-graded polysaccharides of Glehnia Radix. Four kinds of polysaccharides of Glehnia Radix (GLP-30, GLP-50, GLP-70, GLP-residual) were fractionated and purified by water extraction and alcohol precipitation. Fourier transform infrared spectroscopy, high performance liquid chromatography, and gel permeation chromatography, scanning electron microscopy, and differential scanning calorimetry-thermogravimetric analysis were used to evaluate the physicochemical properties and structure characteristics of polysaccharides. The antioxidant activities were also studied. The four polysaccharides of Glehnia Radix have the typical groups of polysaccharides, but the results of differential scanning calorimetry are quite different, which may be due …

Taking the Prunus mira nut as raw material, the oil and protein of were synchronous extracted by aqueous extraction method combined with enzymatic demulsification, the extraction process was optimized by orthogonal tests based on single factor experiment. The main physicochemical indexes of Prunus mira nut oil were determined, and the fatty acid compositions were analyzed by GC. The results indicated that the Prunus mira nut protein yields were(78.13±1.53)%, and oil total yields were(67.79±2.97)%, the optimal oil and protein extraction process were obtained as followed: sample size 150 mesh, liquid-solid ratio 8：1 (mL/g), pH 10, extraction temperature 50 ℃, extraction time …
