[Study of inorganic elements in silybum marianum: distribution and extraction rate].

The contents of multiple inorganic elements in silybum marianum products in different processing stages, including dry fruit, seedcake and extracts, were simultaneously measured by inductively coupled plasma atom emission spectrometry (ICP-AES) and inductively coupled plasma mass spectrometry (ICP-MS). The results indicated that the contents of the elements are the highest in the seedcake and the lowest in the extracts. Moreover, the different decoctions of Silybum marianum fruit made for different immersion times were determined.
