中文摘要:

      目的 调查云南省文山州新鲜三七花、根、茎、叶中钾和磷含量的分布情况。方法 按照 GB 5009.268-2016《食品安全国家标准 食品中多元素的测定》中电感耦合等离子体发射光谱法对随机采集的文山州出产新鲜三七花、根、茎和叶各40份样品中的钾、磷含量进行测定, 使用SPSS软件对数据进行分析。 结果 160件样品中钾含量范围为64.98~2307.84 mg/100 g, 其中花、根、茎、叶中钾含量分别为948.05 mg/ 100 g、282.65 mg/100 g、334.51 mg/100 g、517.42 mg/100 g; 磷含量范围为21.05~951.70 mg/100 g, 其中花、根、茎、叶中磷含量分别为355.17 mg/100 g、94.33 mg/100 g、61.86 mg/100 g、74.47 mg/100 g。结论 云南省文山州新鲜三七中钾含量由高到低依次为花、叶、茎、根, 磷含量由高到低依次为花、根、叶、茎, 三七花的钾含量和磷含量都远高于其他部位, 在文山州8个地区中, 马关县产三七中钾含量和磷含量较高, 广南县产三七中钾含量和磷含量较低。

英文摘要:

      Objective To investigate the distribution of potassium and phosphorus content in fresh Panax notoginseng flowers, roots, stems and leaves in Wenshan prefecture in Yunnan province. Methods According to GB 5009.268-2016 National food safety standard-Determination of many elements in food, the contents of potassium and phosphorus in 40 samples of fresh panax notoginseng produced in wenshan prefecture were determined by inductively coupled plasma emission spectrometry. SPSS software was used to analyze the data. Results The potassium contents in 160 samples were 64.98~2307.84 mg/100g, the potassium contents in flowers, roots, stems and leaves were 948.05 mg/100 g, 282.65 mg/100 g, 334.51 mg/100 g, 517.42 mg/100 g respectively. the range of phosphorus content were 21.05~951.70 mg/100 g, the phosphorus contents in flowers, roots, stems and leaves were 355.17 mg/100 g, 94.33 mg/100 g, 61.86 mg/100 g, 74.47 mg/100 g, respectively. Conclusion The content of potassium in fresh Panax notoginseng from Wenshan prefecture in Yunnan province was flower, leaf, stem and root from high to low. The content of phosphorus from high to low was flower, root, leaf and stem. The potassium content and phosphorus content of Panax notoginseng were both far higher than other parts. In the eight regions of Wenshan prefecture, the potassium content and phosphorus content of Panax notoginseng in Maguan county are higher, and the potassium content and phosphorus content in Panax notoginseng of Guangnan county are lower.
