Concentration level of nine elements viz. Zn, Cu, Mn, Fe, Co, Na, K, Ca, and Li were determined in leaves and roots of Asparagus curillus (Buch.-Ham.) ex Roxb. collected from four different altitudes in three seasons by atomic absorption spectroscopy. The overall concentration of K was found to be highest, whereas the level of Cu was lowest. The maximum concentrations of Zn, Cu, Mn, Fe, Co, Na, K, Ca, and Li were found to be 97.0 +/- 1.5, 28.0 +/- 7.0, 44.0 +/- 7.3, 1138.0 +/- 18.5, 91.0 +/- 6.2, 381.0 +/- 7.8, 9508.0 +/- 7.8, 3076.0 +/- 6.4, and 78.0 +/- 4.6 mg/kg, respectively.
采用原子吸收光谱法测定了从三个季节的四个不同海拔高度采集的芦笋（Buch.-Ham.ex Roxb.）的叶和根中的九种元素（锌、铜、锰、铁、钴、钠、钾、钙和锂）的浓度水平。发现 K 的总浓度最高，而 Cu 的水平最低。Zn、Cu、Mn、Fe、Co、Na、K、Ca 和 Li 的最大浓度分别为 97.0 +/- 1.5、28.0 +/- 7.0、44.0 +/- 7.3、1138.0 +/- 18.5、91.0 +/- 6.2、381.0 +/- 7.8、9508.0 +/- 7.8、3076.0 +/- 6.4 和 78.0 +/- 4.6 mg/kg。
