摘要
产地群众反映我国特有植物太行菊茶饮或药用效果远优于其近缘属的传统药食兼用野菊,为深入研究太行菊,本文比较研究太行菊和野菊不同器官醇提液的抗氧化活性,紫外-可见吸收光谱特性以及抗氧化活性与总黄酮和多酚含量的相关性。结果表明,太行菊和野菊醇提液均有一定抗氧化活性,在一定质量浓度范围,存在剂量效应关系,活性与提取温度相关;太行菊各器官提取液抗氧化活性,紫外-可见光谱吸收峰及总黄酮和多酚含量高于野菊对应器官;相关性分析结果显示,总黄酮和多酚对菊试样抗氧化活性有较大贡献,ABTS和DPPH两种抗氧化活性评价方法间存在较高相关性。太行菊较于野菊可能具有更好的保健或药用功效,有待合理开发利用。
Opisthopappus taihangen^is （Ling） Shih as tea or medicine was found to possess superior efficacy than Den- dranthema indicum by people in place of their origin. Alcoholic extracts of different organs of 0. taihangensis and D. in- dicum were analyzed for their antioxidant capacities, UV-Vis spectral characteristics and the relationship between antioxi- dant capacity and total polyphenols and flavonoids contents. Correlation coefficients were calculated to characterize the relationship between antioxidant capacities and total polyphenols and flavonoids contents. The results showed that alcoholic extracts of different organs of 0. taihangensis and D. indicum exhibited antioxidant activities related with the extraction temperatures and dosage. Alcoholic extracts of different organs of 0. taihangensis showed stronger antioxidant activities and higher UV-Vis absorbanee values and total polypbenols and flavonoid contents than that of D. ind/cum. Furthermore, the antioxidant activities were significantly correlated with total palyphenols and flavonoid contents. Hence, it was concluded that 0. taihangensis was better for health-promoting than D. Indicum, and huge utilization potential was expected from the whole plant of 0. taihangensis.
