- ... In the present study, the digestion properties of a polysaccharide from Rosa roxburghii fruit (RTFP-3) under saliva, simulated gastric and small intestinal conditions were studied for the first time. The results indicated that human saliva had no effect on RTFP-3. RTFP-3 was slightly degraded in simulated gastric and small intestinal juices. The molecular weight (Mw) of RTFP-3 was decreased from 6 ...

- ... Superoxide dismutases (SODs) were purified from sea buckthorn and chestnut rose by ammonium sulfate precipitation and anion‐exchange chromatography, and the detection methods of water‐soluble tetrazolium‐1 (WST‐1), nitrobluetetrazolium (NBT) and pyrogallol autoxidation (PA) for SOD activity were compared. WST‐1 method was selected due to its coefficient of variation (CV) <6% in this study. Two SOD ...
