| Abstract: | Objective： To quantitate flavonoids and quercetin in Tianlong Kechuanling of polyherbal formulations. Methods ： Total flavonoids and quercetin were quantitated by UV-Visible spectrophotometry and High proficiency liquid chromatography （ HPLC ）. Results ： The standard curve of total flavonoids was linear in the range of 0.008-0.048 mg mL-1 （ r=l ）, and the average recovery ratio was 98.98%, and the RSD wasl.65%. The standard curve of quercetin was linear in the range of 0.0168-0.0840 mg mL-1 （ r=0.9999 ）, and the average recovery ratio was 99.83%, and the RSD was 2.03%. Conclusion ： We have identified and quantitated flavonoids and quercetin in Tianlong Keehuanling. The method of quantitive analysis of total flavonoids and quercetin in Tianlong Kechuanling is reliable and able to be used for the quality control of the formula. |
