独根草不同部位几种化学成分的分析比较

为评价独根草这一药赏两用植物,对独根草根、茎和叶中粗灰分、粗纤维、粗脂肪、还原糖、部分矿质元素及活性成分(多糖、绿原酸和总黄酮)进行了测定分析.结果表明:独根草叶中粗灰分、粗纤维、粗蛋白、粗脂肪及还原糖的含量分别为10.11％、8.02％ 、9.54％、9.91％和6.53％；Fe、Zn、Cu、Mn、K、Na、Ca和P等矿质元素含量分别为284、132.8、1.07、19.5μg/g、7.01 mg/g、169.38μg/g、221.9 μg/g和300.5 μg/g;还含有2.00％的绿原酸、6.98％的总黄酮,以及3.29％的粗多糖.叶中各成分含量多高于茎和根,证明其主要药用成分在叶；而茎和根均含有多种元素和活性成分,有一定的药用价值,是一种可以全株入药的药赏两用植物.

Analysis and Comparison of Chemical Composition in Different Parts of the Oresitrophe rupifraga Bge

In order to evaluate plant Oresitrophe rupifraga Bge which can be use for medicine and ornament,the crude ash,crude fiber,crude fat,reducing sugar,some mineral elements(Fe、Zn、Mn、Cu、K、Na、Ca、P) and effective components(polysaccharide,chlorogenic acid and total flavones) in the roots,stems and leaves of Oresitrophe rupifraga Bge were determined and analyzed.The results showed that there were 10.11% of crude ash,8.02% of crude fiber,9.54% of crude protein,9.91% of crude fat,6.53% of reducing sugar,2.00% of chlorogenic acid,6.98% of total flavones and 3.29% of crude polysaccharide,and the content of Fe,Zn,Cu,Mn,K,Na,Ca and P was 284,132.8,1.07,19.5 μg/g,7.01 mg/g,169.38 μg/g,221.9 μg/g and 300.5 μg/g,respectively,in the leaves of O.rupifraga.The contents of ingredients in the leaves were higher than those in the stems and roots,which proved that the main medicinal ingredients were in the leaves.Moreover,there were many mineral elements and active ingredients in the stems and roots,which had certain medicinal value.Therefore,the whole plant might be used as medicine and ornament.
