Abstract: Background

Although traditional Chinese medicine already has been deeply studied in recent years, the contents of elements such as potassium, sulfur, chromium, etc., in patented medicine are hardly been investigated, and test reports for toxicity of heavy metal are limited, etc.

Purpose

This study aims to establish related work for sulfur and other heavy metals in patent medicine and give quantitative analysis.

Methods

First of all, Several common plants, animals and Chinese patent drugs were takes as experimental samples. Then, experiments were carried out by self-made XRF (X-ray fluorescence) instrument with detection limit, except potassium under 90 mg?kg?1, under 20 mg?kg?1 and commercial inductively coupled plasma emission spectromter with detection limit under 30 mg?kg?1. Finally, the contents of sulphur, potassium, chromium, manganese, vanadium and zirconium in these samples were analyzed and studied.

Results

Experimental results show that all the test samples contain high-level of potassium and almost all samples, especially those in patent group, contain high sulfur content but very low-level vanadium and zircon contents. Among some animal samples and all patent samples, the detection of chromium and manganese in excess of standard indicates the need to reduce dosage when not necessary.

Conclusion

According to the provision of general standard of chromium under 0.5 mg?d?1 and manganese under 11 mg?d?1, the tolerable daily intake is made as: phytogroup <2.841 g?d?1, animalia <0.958 g?d?1, patent group <0.935 g?d?1.
