野生豆腐柴总黄酮及微量元素的测定

采用分光光度法和原子吸收测定法,分别对秦巴山区野生豆腐柴中的总黄酮及铁、钙、锌、镁、铜5种微量元素进行了测定。结果表明:秦巴山区野生豆腐柴含总黄酮为6.06%;含5种微量元素为Ca 12 574μg/g、Fe 1 830.5μg/g、Mg 4 312.5μg/g、Zn 41.5μg/g、Cu29.5μg/g。截至目前,豆腐柴中总黄酮及微量元素含量的测定尚未见有类似的报道,故这一测定结果对开发利用豆腐柴这一野生资源起着重要作用。

Determination of Total Flavone and Microelements in Premna microphylla Turcz

The study determines the contents of total flavone,Fe,Ca,Zn,Mg and Cu with spectrophotometer and atomic absorption methods.The results show that the total flavonoid content is 6.06%,Ca is 12 574 μg/g,Fe is 1 830.5 μg/g,Mg is 4 312.5 μg/g,Zn is 41.5 μg/g,Cu is 29.5 μg/g.There isn't a similar report about the determination the total flavone and microelements of premna microphylla turcz,so it plays an important role in researching and developing the resource of premna microphylla Turcz.
