Studies on Stability and Antioxidation of Procyanidins from Lycium Ruthenicum Murray
The stability and antioxidation of procyanidins from Lycium Ruthenicum Murray were studied,the results showed that the procyanidins was quite stable under the avoiding light,natural light or low sunlight conditions,and sensitive to temperature and pH.procyanidins was stable under a low temperature and pH,but the stability would decrease quickly when the temperature was above 50 ℃ or pH values above 6.The procyanidins have strong scavenging effects to ·DPPH radicals,and has the highest scavenging activity when the concentration of procyanidins was below 0.005 mg/mL,the clearance rate of · DPPH was 77.26％.
