ABSTRACT
Objective:
To establish a method for the content determination of triptolide, total diterpenoids and total alkaloids in Leigongteng oral solution to provide basis for the quality control.Methods:
An HPLC analysis was used to detect the content of triptol-ide, which was carried out on an Eclipse XDB-C18 column (150 mm × 4. 6 mm, 5μm) with the mobile phase consisting of acetonitrile-water with gradient elution. The flow rate was maintained at 1. 0 ml·min-1 , the column temperature was kept at 40℃ and the detec-tion wavelength was set at 218 nm. Using triptolide and wilforine as the contrast, the total diterpenoids and total alkaloids were deter-mined by UV-Vis spectrophotometry.Results:
There were good linear relationship in the determination of triptolide, total diterpenoids (caculated as triptolide) and total alkaloids (caculated as wilforine) (r≥0. 999 8), the average recovery were 91. 96%, 90. 56%, 99. 18%, and the RSD were less than 3%.Conclusion:
The method is with good reproducibility and stability, which can be used for the quality control of Leigongteng oral solution.
