Character Study of Content and Correlativity of Elements in Propolis Obtained from Different Regions

OBJECTIVE To study content and correlativity of elements in propolis obtained from different regions. METHODS The content of elements in propolis samples from different country and provinces were determined by ICP-MS, AFS and ASS. The correlation of elements in propolis was analyzed by statistic software(SPSS). RESULTS Firstly, it was observed that the content of metal elements in propolis from high to low was K, Ca, Na, Fe. Seven groups of elements were related(P<0.05) or related obviously(P<0.01), especially Ca and Fe, Ca and Mg, Mg and K were related obviously. Secondly, the content of longevity elements in the samples from high to low was Co, Mo, Se and Mn. Se and Mn was related obviously(P<0.01). Thirdly, As and Cd were low in samples, while Pb, Hg, Cr, Ni were different obviously. CONCLUSION It is concluded that element content in propolis are special different with aid of soil, climate and natural environment. Some elements show certain relationship.
