| 摘 要： | 研究玫瑰茄的体外抗氧化活性。采用不同极性的有机溶剂萃取玫瑰茄40%乙醇提取物(粗提物),得到石油醚萃取物、氯仿萃取物、乙酸乙酯萃取物、正丁醇萃取物,然后采用Folin-Ciocalteu比色法测定粗提物以及各萃取物的多酚含量,同时应用DPPH法、试剂盒法、ABTS法分别测定粗提物和各萃取物的DPPH自由基清除能力、还原Fe3+能力以及ABTS自由基抑制能力。DPPH法、试剂盒法、ABTS法测定各提取物抗氧化能力的结果为粗提物>正丁醇萃取物>乙酸乙酯萃取物>氯仿萃取物>石油醚萃取物。玫瑰茄提取物具有较高的多酚含量和较强的抗氧化能力;玫瑰茄提取物的多酚含量与抗氧化能力之间存在较好的相关性。

| Abstract: | Antioxidant activities of Hibiscus sabdariffa extracts with petrol ether,chloroform,ethyl acetate,butanol and 40 % ethnol were studied respectively.Then the phenolic content of extracts was determined by using Folin-Ciocalteu colorimetry.The antioxidant activities of extracts were measured by DPPH radicals scavenging activity assay,Fe3+ reducing power assay and ABTS radicals restraining activity assay.On those assays,the antioxidant activity of extract in 40 % ethnol,in butanol,in ethyl acetate,in chlorofor... |
