Ginseng years can be identified by biotechnology
Ginseng is known as the "King of Herbs". However, for a long time, the identification of its age relies on the experience of old pharmaceutical workers to make it difficult to quantify, standardize and digitize. On January 23, a research report published by the team of Huang Yiqi of the Chinese Medicine Resource Center of the China Academy of Chinese Medical Sciences in the journal Nature Reports will fundamentally solve this problem.
The results of this study extracted DNA from ginseng cells and identified ginseng growth years using telomere length and telomerase activity. The researchers analyzed the average telomere length of ginseng by TRFs. From the second year onwards, the telomere length of ginseng increased with the extension of its age, and based on this, a mathematical model related to ginseng age and telomere length was established.
