摘　　要：目的　对比分析国家一类动物药塞隆骨和禁用传统中药材虎骨中的 19种矿物质元素的含量。方法　骨骼样品经灰化或消解处理后 ,采用原子吸收光谱法、氢化物原子荧光光谱法、催化极谱法等分析方法测定矿物质元素。结果　两种动物骨骼中元素含量差异显著 ,塞隆骨 11种元素高于虎骨 ,特别是 Cu、Zn、Fe、Mn、Se等生命活动必需微量元素塞隆骨极为显著地高于虎骨 ,而组成骨骼的主要成分 Ca、P则为虎骨高于塞隆骨。矿物质元素在头骨、脊梁骨和腿骨中分布非常不平衡 ,多数元素以头骨中分布最为丰富 ,而 5种常量元素 Ca,P,Na,Mg,K的含量为腿骨 >头骨 >脊梁骨。骨骼中主要成分 Ca和 P的存在形式主要为羟磷灰石 Ca1 0 (PO4 ) 6 (OH) 2 。结论　塞隆骨骨骼中的矿物质元素与虎骨有可比性 ,必需微量元素塞隆骨明显优于虎骨。Object The contents and distribution of 19 mineral elements in Sailong bone and tiger hone, which are the first-class national animal medicinal materials and the banned Chinese materia medicas respectively, were analyzed and compared. Methods After the skeleton samples were reduced into ashes or digested, 19 mineral elements were determined by atom absorption spectrometer (AAS), hydride generation atomic fluorescence spectrometry (HAFS), and catalytic wave oscillopolarograph (CWOP). Results The contents of mineral elements were significantly different in the two kinds of animals' bone. By comparison, the contents of 11 elements in Sailong bone were higher than those in tiger bone, and especially the contents of Cu, Zn, Fe, Mn, Se, etc., which were essential for life activities, were much higher in Sailong bone. However, the contents of Ca and P, the main components of skeleton, were higher in tiger bone. Moreover, the distribution of mineral elements were not so average in the head bone, backbone, and leg bone, the most mineral elements were the richest in head bone. However, the content distribution trend of five macro-elements (Ca, P, Na, Mg, and K) was: leg bone > head bone > backbone. The existing form of Ca and P in the skeletons of Sailong and tiger was mainly Ca 10(PO 4) 6(OH) 2. Conclusion The mineral element contents in the skeletons of Sailong and tiger bone have the comparability. It shows that the contents of essential trace elements in Sailong bone are prior to those in tiger bone, significantly.
