[The extraction of DNA from milligram amounts of wild mountain ginseng tissues]
1Institute of Medicinal Plants, Chinese Academy of Medical Sciences and Peking Union Medical College, Beijing 100094.
Objective:
To keep wild mountain ginseng, a rare medicinal remedy, as intact as possible when extracting DNA from it, a new way to extract DNA has been explored.
Method:
The CTAB method was improved and a simple and direct way was developed.
Result:
From 0.001 g of dried samples of ginseng root DNA was obtained in an amount up to 2.25 micrograms.
Conclusion:
The RAPD fingerprinting generated by this DNA is as good as that by CTAB method. This new method may also be used for extraction of other precious Chinese medicinal materials.
