目的:为充分利用三七地上部分植物资源,对不同产地的三七茎叶和花的主要营养成分和矿质元素含量进行分析。方法:采用国家标准方法对不同产地三七地上部分的水分、灰分、粗脂肪、粗纤维、粗蛋白、矿质元素含量等进行测定。结果:三七地上部分茎叶和花含有较高的蛋白质、粗纤维、较低的脂肪含量以及大量的矿质元素,其中以锌(Zn),铁(Fe),锰(Mn),钙(Ca),镁(Mg)的含量较高。结论:三七茎叶和花含有丰富的营养元素和矿质元素,可以作为新资源食品进行开发。

Objective： To make full use of the plant resources of Panax notoginseng, nutritional compositions and mineral elements were analyzed in aerial part of P. notoginseng from different areas in Yunnan. Method： Using the national standard method, water, ash, crude fat, crude fiber, crude protein and mineral elements were determined in aerial part of P. notoginseng from different growing areas. Result： Results showed that there were higher contents of crude fiber and crude protein, and lower content of crude fat in the stems and flowers of P. notoginseng. Meanwhile, a large number of mineral elements were determined in two locations of P. notoginseng, and the contents of Zn, Fe, Mn, Ca and Mg were obvious higher among these mineral elements. Conclusion： This study showed that the stems and flowers of P. notoginseng were nutritious and suggested that the aerial part may be utilized as new resources foods.
