摘  要:
本文分别以水、甲醇和乙醇为溶剂从新疆恰玛古中浸提皂苷,并对其清除DPPH、·OH、·O2-自由基的活性进行了研究。试验结果表明:在试验浓度范围内,恰玛古皂苷浓度与清除自由基能力呈量效关系,但均低于Vc清除自由基的能力,差异显著(P≤0.01)。

摘  要:
Saponins from Brassica campestris L. were extracted with water, methanol and ethanol, respectively,and their free radical scavenging activity was also studied in this paper. The experiment's results showed that saponins could be extracted form Brassica campestris L. using different solvent. However, the extracting yield of ethanol and methanol were higher than water(P≤0.01). In the present study, there were dose-effect relationships between free radical scavenging activity and the concentration of saponins of Brassica campestris L., and its scavenging activity was weaker than that of Vc(P≤0.01).
