摘要: 旨在探讨新疆伊犁蜂胶和库车蜂胶不同溶剂提取物清除1,1-二苯基苦基苯肼(DPPH)自由基和抗油脂过氧化力的作用,并测定新疆伊犁蜂胶的主要生物活性物质槲皮素和白杨素的含量。处理原蜂胶,以4 种溶剂提取蜂胶,用DPPH 自由基法和抗亚油酸过氧化法对新疆伊犁蜂胶和库车蜂胶提取物进行抗氧化活性的测定。以70% 乙醇和甲醇作为提取溶剂从新疆伊犁蜂胶中提取槲皮素和白杨素;用高效液相色谱法对所提取的槲皮素和白杨素进行含量测定,测定波长分别为370 nm 和268 nm。结果显示,对DPPH 自由基的清除能力在蜂胶不同提取物和不同浓度之间则有差异,部分试验组的清除能力优于同浓度的茶多酚;对亚油酸均有抗氧化活性,其中伊犁蜂胶抗亚油酸过氧化活性较好。在乙醇提取液里槲皮素的含量最低,为2.2950 mg/g,而在经脱脂的甲醇提取液里其含量最高,为2.8150 mg/g ;在甲醇提取液里白杨素的含量最低,为60.72 mg/g,而在经脱脂的甲醇提取液里其含量最高,为74.37 mg/g。伊犁和库车蜂胶具有一定的抗氧化作用;DPPH 自由基法是一种快速、灵敏、简便的方法,结果表明,新疆产蜂胶可作为天然抗氧化剂进一步开发和利用;经过高效液相色谱法(HPLC)的分析结果表明,活性成分槲皮素和白杨素从新疆伊犁蜂胶样品中可被检测出。

Abstract: To study the DPPH free radical scavenging activity and anti-lipid peroxidation activity of Kuqa and Yili, and determine the content of the Quercetin and Chrysin in Xinjiang Yili propolis. Different extracts of raw propolis were extracted by four kinds of solvents, taking tea polyphenol as comparison; measure Kuqa and Yili, Xinjiang propolis extracts antioxidant activity in removal of DPPH(1, 1-Diphenyl- 1-picrylhydrazyl)free radicals and antioxidant properties of linoleic acid peroxidation. With 70% ethanol and methanol as solvent to extract Quercetin and Chrysin from Xinjiang Yili propolis, using HPLC(high performance liquid chromatography)to determine the content of the extracted Quercetin and Chrysin, the detection wavelength was 370 nm and 268 nm, respectively. Result showed that propolis different extracts in different concentrations has different scavenging free radical DPPH capacity, in partial experimental groups’ scavenging capacity is even surpassed to same concentration of tea polyphenol group; has antioxidant activity to linoleic acid, in which Yili propolis has higher antiperoxidation activity. The content of Quercetin was the lowest in the without defatted ethanol extracts(2.2950 mg/g), the highest in the defatted methanol extracts(2.8150 mg/g);The content of Chrysin was the lowest in the without defatted methanol extracts(60.72 mg/g), the highest in the defatted methanol extracts(74.37 mg/g). The Kuqa and Yili propolis has a certain extent of antioxidant capacity, this DPPH method is fast, sensitive and simple, this results showed that the Xinjiang propolis is a natural antioxidant, and waiting for further study and utilization; HPLC analysis showed that Quercetin and Chrysin the active ingredients of propolis samples from Xinjiang Yili were detected.
