    Abstract:
    Honeysuckle is a lonicera plant, commonly used traditional precious raw material for medicine in China, and is a commonly used Chinese native medicine and an important material for cold drink. Honeysuckle has the effect of alleviating fever and disintoxicating, and is used mainly to treat the carbuncular swelling, and cure boils, throat rheumatism, erysipelas, painfully hot sun blood dysentery, cold, and various diseases accompanied by fever. The simultaneous determination of multi-metal elements in honeysuckle was studied by inductively coupled plasma atomic emission spectrum (ICP-AES) after carbon pick-up acid dissolvation digestion. The average recovery of the method for Cu, Mn, Ni, Pb, Fe, Cr, Ca and Mg in honeysuckle was found to be 83.8%-115.6%, while RSD (n = 10) is 1.1%-4.9% for the multi-elements in honeysuckle. The method was applied to the analysis of some practical samples and the results obtained were satisfactory. Fe and Mn are rather rich in honeysuckle. It is of important significance to assess the value of the food cooked with medicinal herbs by the determination of multi-trace elements.
