Abstract
Objective:
To establish a method for the determination of triptophenolide in Chinese herb Leigongteng (Tripterygium wilfordii Hook. f.).
Method:
TLCS was used. The sample was purified with a column and developed upwardly with CHCl3-EtOEt(2:1), sprayed with Keddle testing solution and scanned. The content was calculated with external two-point method.
Result:
The linear range was 2.1 micrograms-10.5 micrograms, r = 0.998.
Conclusion:
The method is proper for the quality control of Leigongteng.
