荷叶蜡质层处理与荷梗品质及抗氧化性

Qualities and antioxidant activities of lotus leaf wax layer treatment and lotus petioles

为了探索荷叶蜡质层是否影响荷叶品质,明确荷梗的品质及其抗氧化性,主要研究了打磨荷叶、无打磨荷叶和荷梗的活性成分、营养成分和抗氧化性.实验结果表明:无打磨荷叶的活性成分和营养成分含量(维生素C含量除外)显著高于打磨荷叶的活性成分和营养成分含量,而打磨荷叶的抗氧化性显著高于无打磨荷叶的抗氧化性.荷梗的生物碱含量较高,同时抗氧化性也较强.因此,荷梗具有重要的开发潜能.

The paper mainly discussed the qualities and the antioxidant activities in the polished lotus leaves, the unpolished lotus leaves and the lotus petioles, in order to exploring whether the wax layer on lotus leaves affect the qualities of lotus leaves, and to indentifying the quality and antioxidant activity of lotus petioles. The results showed that the active and nutritional ingredients(except for vitamin C content) of the unpolished lotus leaves were significantly higher than that of the polished lotus leaves. The antioxidant activities of the polished lotus leaves were significantly higher than that of the unpolished lotus leaves. Lotus petioles showed high alkaloid content and powerful antioxidant activity. Therefore, lotus petioles have great potential to be utilized.
