關鍵字: | Antioxidant activity; Cunninghamia konishii; Ethanolic extract; Isolariciresinol; Lanceolatanin D | 公開日期: | 2015 | 卷: | 64 | 起(迄)頁: | 39-44 | 來源出版物: | Industrial Crops and Products | 摘要: | Antioxidant potencies of ethanolic extract and its compounds from Cunninghamia konishii wood were investigated and reported for the first time. The results revealed that among five soluble fractions derived from ethanolic extract, the EtOAc soluble fraction possesses the highest antioxidant activity. The bioassay-guided fractionation yielded two potent antioxidant constituents from subfraction E2, namely lanceolatanin D (. 1) and isolariciresinol (. 2). Both lanceolatanin D (. 1) and isolariciresinol (. 2) exhibited DPPH radical, superoxide anion radical scavenging, and reducing power activities. Therefore, C. konishii wood ethanolic extract and its compounds are great sources of antioxidants for improving human health. ? 2014 Elsevier B.V. |
