采用微波消解前处理, 全反射X射线荧光分析法(TXRF)同时测定松花粉中16种元素, 并对马尾松、 云南松、 油松、 黑松、 赤松等五种松花粉中16种元素含量进行了测定与比较。 结果表明: 五种松花粉中都含有这16种元素; Ca, Ti, Mn, Zn和Rb等五种元素平均含量在不同树种间均存在极显著性差异(p≤0.01); K, V, Fe, Co, Cu和Sr等六种元素平均含量在不同树种间均存在显著性差异(p≤0.05); Cr, Ni, As, Pb和Se等五种元素平均含量在不同树种间不存在显著性差异(p＞0.05); 研究还表明松花粉具有温性或偏寒凉性药的元素谱征。 研究结果可以初步断定, 松花粉中这16种元素的含量和树种有关, 和生长环境、 地域等密切相关。

After microwave digestion, 16 elements in pine pollen were simultaneously determined by TXRF. The results show that all the 16 elements were found in all pine pollens. There was a significant difference in the average content of the element such as Ca, Ti, Mn, Zn and Rb between different groups of pine pollen (P≤0.01). There was a difference in the average content of the element such as K, V, Fe, Co, Cu and Sr between them (P≤0.05). And there was no difference in the average content of the element such as Cr, Ni, As, Pb and Se between them. The results also show that pine pollen has the spectral characteristics of warm property or cold property drug. They were closely related to the tree species and the growth environment or the growth area.
