ABSTRACT
[Objective] To establish a method for the determination of ferulic acid and salvianolic acid B contents in Yixin Tablets. [Methods] High pressure liquid chromatography (HPLC) was adopted. The chromatographic conditions were: 100-fold methanol as solvent, Bonification for 30min, gradient elution on C18 comlumn with acetonitrile and phosphoric acid as mobile phase, the detection wavelength being 320nm. [Results] Ferulic acid had a good linearity in the range of 0.024 32 - 0.729 60 ?g and r=0.999 9; salvianolic acid B had a good linearity in the range of 0.416 8-12.504 0?g and r = 0.9999; the average recovery rate was 100.95% in ferulic acid and 99.35% in salvianolic acid B respectively. [Conclusion] This method is simple, accurate and with good reproducibility.
ABSTRACT
Objective To select the herba anti- human papillomavirus (HPV) active fraction from herba Arnebia. Methods The fractions from herba Arnebia. were separated with systematic solvents including petroleum arieal part of benzin, n- butanol , ethanol and distilled water, and their effects on HPV- DNA were evaluated by fluorescence quantitative polymerase chain reaction (FQ- PCR) technique. Results Only the water- extract of.this drug showed in- vitro inhibitory effect on HPV- DNA and its minimum effective concentration is 0.08g/mL. Conclusion Herba Arnebia. has in- vitro inhibitory effect on HPV- DNA and the active components exists in the water- extract.
