条叶榕营养成分分析及黄酮含量的测定

Analysis of the nutritional components and content determination of total flavonoids in Ficus pandurata hance var.angustifolia Cheng

以野生条叶榕为研究对象,对其叶、茎、根的化学营养成分、氨基酸组成、矿质元素组成进行了分析。同时,对条叶榕总黄酮的测定条件进行了分析,并测定其总黄酮含量。结果表明,条叶榕的叶、茎和根均富含蛋白质、粗脂肪、粗纤维、总糖、维生素C,其叶中的含量最高;条叶榕中氨基酸种类齐全,必需氨基酸与总氨基酸比例合理;条叶榕富含Cr、Mn、Fe、Cu、Zn、As、Se、Ag、Cd、Hg和Pb,其中Mn、Fe、Zn的含量较高;采用盐酸-镁粉显色法测定条叶榕中总黄酮含量,该方法简便、快速、准确,测得其总黄酮含量为12.74g/kg。测定结果说明,条叶榕具有一定的营养保健功能。

Taking Ficus pandurata hance var.angustifolia Cheng as object,nutrional components,amino acids components and mineral elements components in leaves,stem and root were analyzed. Determination conditions of the flavonoid were also studied,and the content was determined. The result showed that protein,crude fat, crude fiber,total sugar and vitamin C were rich in leaves,stems and roots of Ficus pandurata hance var. angustifolia Cheng,particularly the content of leaves were the most. The complete compositions of amino acids existed in Ficus pandurata hance var.angustifolia Cheng,and there were well balanced with reasonable proportion of essential amino acids and total amino acids. There were rich in essential trace elements Cr,Mn, Fe,Cu,Zn,As,Se,Ag,Cd,Hg and Pb in Ficus pandurata hance var.angustifolia Cheng,particularty the content of Mn,Fe,Zn were much more. The toatal flavonoid in Ficus pandurata hance var.angustifolia Cheng was measured by hydrochloric acid-Mg as developing reagents,this method was simple,rapid and accurate. The toatal flavonoid content of Ficus pandurata hance var.angustifolia Cheng was 12.74g/kg. The test showed that Ficus Dandurata hance var.anaustifolia Chena had nutritive value and health function.
