- Abstract
Thirteen trace elements and active constituents of 40 batches of <italic>Lonicera japonica flos</italic> and <italic>Lonicera flos</italic> were comparatively studied using inductively coupled plasma mass-spectrometry (ICP-MS) and high-performance liquid chromatography-photodiode array (HPLC-PDA). The trace elements were 24Mg, 52Cr, 55Mn, 57Fe, 60Ni, 63Cu, 66Zn, 75As, 82Se, 98Mo, 114Cd, 202Hg, and 208Pb, and the active compounds were chlorogenic acid, 3,5-<italic>O</italic>-dicaffeoylquinc acid, 4,5-<italic>O</italic>-dicaffeoylquinc acid, luteolin-7-<italic>O</italic>-glucoside, and 4-<italic>O</italic>-caffeoylquinic acid. The data of 18 variables were statistically processed using principal component analysis (PCA) and discriminate analysis (DA) to classify <italic>L. japonica flos</italic> and <italic>L. flos</italic>. The validated method was developed to divide the 40 samples into two groups based on the PCA in terms of 18 variables. Furthermore, the species of <italic>Lonicera</italic> was better discriminated by using DA with 12 variables. These results suggest that the method and statistical analysis of the contents of trace elements and chemical components can classify the <italic>L. japonica flos</italic> and <italic>L. flos</italic> using 12 variables, such as 3,5-<italic>O</italic>-dicaffeoylquincacid, luteolin-7-<italic>O</italic>-glucoside, Cd, Mn, Hg, Pb, Ni, 4-<italic>O</italic>-caffeoyl-quinic acid, 4,5-<italic>O</italic>-dicaffeoylquinc acid, Fe, Mg, and Cr.
