Analysis on mineral element contents in Nadao capsicum and Xiaomi capsicum from Shiping of Yunnan Province _ | 云南石屏那刀辣与小米辣矿质元素含量分析

Chinese. ［目的］为云南石屏县那刀辣与小米辣的开发利用提供科学依据。［方法］以石屏县那刀辣与小米辣为材料，采用原子吸收光谱法测定其中的矿质元素含量。［结果］小米辣Ca、Fe含量分别比那刀辣高235.0、4.1 mg/kg，那刀辣Mg、Zn、Cu、Co、Ni含量分别比小米辣高71.20、_0.84_、0.02、0.125、1.05 mg/kg；2种辣椒Mg含量最高，分别为1 948.3和1 877.1 mg/kg，Ca含量次之，分别为347.5、582.5 mg/kg，Co含量最低，分别为0.650 0、0.525 0 mg/kg；2种辣椒所分析7种矿质元素的含量依次为：MgCaFeZnCu NiCo，矿质元素的加标回收率为_97.18_%～107.77%，测定结果的相对标准偏差为0.43%～1.86%。［结论］那刀辣与小米辣中矿质元素含量存在一定差异。

English. ［Objective］ The aim was to provide the scientific basis for the development and utilization of Nadao capsicum and Xiaomi capsicum from Shiping of Yunnan Province. ［Method］With Nadao capsicum and Xiaomi capsicum from Shiping Country as the materials, their mineral element contents was determined by atomic absorption spectrometry. ［Result］ The contents of Ca and Fe in Xiaomi capsicum were higher 235.0 and 4.1 mg/kg than those in Nadao capsicum resp., while the contents of Mg, Zn, Cu, Co and Ni in Nadao capsicum were higher 71.20, 0.84, 0.02, 0.125 and 1.05 mg/kg than those in Xiaomi capsicum. Mg content in 2 kinds of capsicum was the highest, being 1 948.3 and 1 877.1 mg/kg resp., and the following was that of Ca, being 347.5 and 582.5 mg/kg resp., Co content in 2 kinds of capsicum was the lowest, being 0.650 0 and 0.525 0 mg/kg resp. The contents of 7 kinds of analyzed mineral element in 2 kinds of capsicum in order was: MgCaFeZnCu NiCo, and the recovery of standard addition of the mineral elements was 97.18%-107.77% with relative standard deviation of 0.43%-1.86%. ［Conclusion］ The mineral element contents in Nadao capsicum and Xiaomi capsicum had some differences.
