中药琥珀及其伪品的鉴定

An Appraisal of the Traditional Chinese Medicine Amber and Its Counterfeit

用偏光显微镜、电子显微镜等对琥珀及其伪品进行了对照鉴定，并用等离子体发射光谱进行了微量元素分析。结果伪品是蛋白石；煤珀与蛋白石都含有35种微量元素，蛋白石含Ca、Mg、Al、Fe量大于煤珀10～70倍，亦可作为鉴别的依据。

Distinction between the traditional Chinese medicine amber and its counterfeit was studied by polarizing microscope and electron microscope, and trace clements analyse d by plasma spectroscopy. Results showed that the counterfcit of amber is opal, which contains the same thirty-five kinds of trace elements as coal amber. The total amount of Ca, Mg, Al,and Fe contained in opal is 10 to 70 times more than that contained in coal amber, whichcau provide a basis for the appraisal of coal amber and opal.
