摘要

[Objectives] This study was conducted to establish an analytical method for the establishment of 13 trace elements in Anshun thorn pear ( Rosa roxburghii ) and golden thorn pear ( Rosa sterilis S. D. Shi).[Methods] Nitric acid was used as the digestion system for microwave digestion. Inductively coupled plasma mass spectrometry (ICP-MS) was used to determine the trace elements in thorn pear and golden thorn pear.[Results] Be, Ti, V, Cr, Mn, Co, Ni, As, Sr, Mo, Cd, Sb and Hg were determined by ICP-MS method in thorn pear and golden thorn pear. The correlation coefficients of the regression equations of the elements were higher than 0.996;the precision RSD was lower than 2.87%;and the recovery ranged from 94.3% to 109.8%.[Conclusions] The method has the advantages of high sensitivity, good accuracy and simultaneous detection of multiple elements, and provides a reference method and theoretical basis for determining trace elements in thorn pear and golden thorn pear and other fruits.
