| 摘 要： | 为探讨UV-B辐射对鲜土贝母有效成分和抗氧化活性的影响,对土贝母(Bolbostemma paniculatum)新鲜块茎的有效成分含量和抗氧化活性进行了研究。结果表明,100 k J m–2的高剂量UV-B辐射使鲜土贝母的还原糖含量升高60.17%,大黄素含量升高209.60%。辐射后还原能力及清除DPPH·自由基能力均显著高于对照(P0.01)。这说明UV-B辐射可显著提高土贝母鲜品的有效成分含量和抗氧化活性,因此鲜土贝母加工前进行UV-B辐射可望提高药材质量。

| Abstract: | In order to understand the effects of ultraviolet-B (UV-B) radiation on active constituents and antioxidant activity in fresh Bolbostemma paniculatum (Maxim.) Franque, the contents of active ingredient and antioxidant activities were studied. The results showed that the contents of reducing sugar and emodin increased by 60.17% and 209.60%, respectively, radiated by 100 kJ m-2 UV-B. Compared to control, the reducing capacity and DPPH· scavenging ability of B. paniculatum significantly enhanced (P<0.01). Therefore, UV-B radiation could increase active ingredient contents and antioxidant activities of B. paniculatum, and its quality could be improved if radiated with UV-B before processed. |
