Revised Chinese Pharmacopoeia 2025: Atomic Fluorescence Spectroscopy for the Detection of Traditional Chinese Medicine
Date: 2025-05-07Read: 0
With the steady progress of the revision of the 2025 edition of the Chinese Pharmacopoeia, the National Pharmacopoeia Committee has recently released important public announcements. The publication of the draft standards for atomic fluorescence spectrometry and the draft standards for lead, cadmium, arsenic, mercury, and copper determination in the 2321 Pharmacopoeia have attracted widespread attention in the field of drug testing.
In this revision, it is explicitly stipulated that atomic fluorescence spectroscopy can be used for the detection of arsenic and mercury in traditional Chinese medicine. Atomic fluorescence spectroscopy is an instrument analysis method based on the absorption of ground state atoms of the element to be measured in the vapor phase by a light source, which excites characteristic spectral lines with fluorescence, and quantitatively analyzes them based on the fluorescence intensity. This method has the characteristics of high sensitivity, high accuracy, and rapid analysis, and is suitable for trace to trace detection of elements that can form hydrides, atomic vapor states, or volatile compounds, such as arsenic, mercury, selenium, tin, etc.

In addition, this revision is applicable to limit inspection and content determination of some heavy metals in Chinese medicinal materials, traditional Chinese patent medicines and simple preparations, chemicals and excipients. This means that atomic fluorescence spectroscopy will play an important role in controlling drug quality, further enhancing the accuracy and reliability of drug testing.
The revised content of the Chinese Pharmacopoeia, as a legal code for recording drug standards and specifications in the country, has a profound impact on the pharmaceutical industry. The inclusion of atomic fluorescence spectroscopy in the detection standards for traditional Chinese medicine not only reflects the acceptance and application of advanced detection technologies in the pharmacopoeia, but also provides stronger technical support for the quality control of traditional Chinese medicine, which helps to ensure the safety of public medication.
