摘  要：
[目的]研究南五味子根黄酮提取物的抗菌抗氧化活性。[方法]采用乙醇和水为溶剂提取南五味子根的黄酮类物质,并对其黄酮提取物进行抗菌及抗氧化试验。[结果]南五味子根醇提黄酮粗提物提取率大于水提,其中醇提法提取率为13.67%,水提法提取率为7.80%。醇提黄酮提取物对黑曲霉的抑菌效果最好,抑菌圈直径达到12.94 mm。南五味子根的黄酮提取物具有抑制羟自由基的能力。醇提黄酮提取物的抑制羟自由基能力高于水提,抑制羟自由基能力随着稀释倍数的增加呈递减趋势。其中稀释100倍醇提时所提取的黄酮类物质抑制能力最强,达13 560.78 U/mL。[结论]根部是贮存抗菌抗氧化活性物质的主要器官,南五味子根具有较强的抗菌抗氧化活性。

摘  要：
[Objective]The research aimed to study the antibacterial and antioxidation activities of flavonoids extract from the roots of Kadsura longipedunculata.[Method]Ethanol and water were used as solvents to extract flavonoids from the roots of Kadsura longipedunculata, and antibacterial and antioxidant tests was made on flavonoids extracts.[Result]The extraction rate of crude flavonoids extract by alcohol extraction from the roots of K. longipedunculata was greater than that by water extraction. The extraction rate of crude flavonoids extract by alcohol extraction rate was 13.67% and that by water extraction rate was 7.80%.The flavonoids extract by alcohol extraction from the roots of K. longipedunculata had the best inhibitory effect on Aspergillus niger,and the diameter of inhibition zone reached 12.94 mm. The flavonoids extract from the roots of K. longipedunculata had the inhibitory effect on hydroxyl radicals. The inhibitory activity of flavonoids extract by alcohol extraction from the roots of K. longipedunculata on hydroxyl radicals was greater than that by water extraction, and the inhibitory activity on hydroxyl radicals showed the decreased trend with the dilution times. The inhibitory activity inhibitory activity of flavonoids extract by diluting 100 times of alcohol with from the roots of K. longipedunculata on hydroxyl radicals was the strongest, reaching 13 560.78 U/mL. [Conclusion]The root is the main organ for the storage of antibacterial and antioxidative active substances. The root of K. longipedunculata had stronger antibacterial and antioxidant activities.
