摘要: 以时间、 温度和料液比3个单因素进行正交实验, 确定葛根中黄酮提取的最佳条件. 结果表明, 提取的最佳条件为: m(料)∶V(液)=(1∶40)g/mL, 60 ℃浸提3 h, 葛根粗提率为82%, 黄酮提取率最高为18.04%. 以模式生物秀丽隐杆线虫(线虫)为模型, 考察质量浓度分别为1,2,5 mg/mL黄酮提取物对线虫的抗氧化作用. 结果表明, 在35 ℃培养12 h, 1 mg/mL[KG*8]黄酮提取物喂食线虫的存活率较对照组有显著提高, 即黄酮提取物有明显的抗氧化作用.

Abstract: The orthogonal experiments were carried out with 3 single factors of time, temperature and ratio of material to liquid. The optimum conditions for the extraction of flavonoids from Pueraria lobata were m(material)∶V(liquid)=(1∶40)g/mL, 60 ℃ as exaction temperature and 3 h as exaction time. The crude extraction rate of P.lobata was 82%, and the highest extraction rate of flavonoids was 1804%. Using the model organism Caenorhabditis elegans as a model, we investigated the antioxidant effects of mass concentrations of 1,2,5 mg/mL of extraction of flavonoids on C.elegans, respectively. The results show that 1 mg/mL flavonoids extracts are fed to C.elegans and cultured 12 h at 35 ℃, the survival rate of C.elegans is significantly higher than that of the control group, i.e., flavonoids extract has obvious antioxidant effect.

Key words: Pueraria lobata, Caenorhabditis elegans, flavonoid, antioxidant
