| titleOfInvention | Simultaneous quantitative detects the method for Ligustilide and Senkyunolide A |
| abstract | Simultaneous quantitative detects the method for Ligustilide and Senkyunolide A. Taking butylphenyl phthaleine as substitute reference substance, the high performance liquid chromatography that is filler with octadecylsilane chemically bonded silica, adopts the single wavelength within the scope of 275～284nm, measures respectively the peak area A of Ligustilide in sample (X) and Senkyunolide A (Y) x And A y , according to the concentration C of substitute reference substance butylphenyl phthaleine (Z) z With peak area A z , use correction factor<i>f</i>Calculate the concentration C of tested composition Ligustilide and Senkyunolide A by following formula. Correction factor wherein<i>f x </i>=0.20～0.25，<i>f y </i><i></i>=0.46～0.54. The testing result of the method is stable,, has solved and must adopt at present dual wavelength to detect and the higher and poor problem of universality to HPLC equipment requirement simultaneously as the method testing result of reference substance is consistent with Ligustilide taking fresh preparation, Senkyunolide A. |
