Identification of Codonopsis Radix and Gentianae Macrophylae Radix by Nonlinear Electrochemistry Fingerprint
Objective: To establish the method for identification of Codonopsis Radix and Gentianae Macrophylae Radix. Method: In a glass reactor with diameter less than 0.125 mm of Chinese herbal medicine powder (accurate to 0.002 g) as the substrate of reaction
the H+-Mn2+-CH3COCH3-BrO3- for oscillation system. Temperature kept at 310 K and the stirring speed was 310 r·min-1. With saturated calomel electrode as reference
the platinum electrode as indicator electrode
the electrochemical workstation records of chemical potential in the oscillation system
along with the change of time. Draw E-t curve using Origin 7.5 software
get the non-linear electrochemical fingerprint. The character of parameters:the highest potential
induction time
oscillation oscillation cycle and service life
calculate the activation energy of reaction
using cluster analysis method to study. Result: The repeatability is good
the non-linear electrochemical fingerprint intuitively see the party to participate in the non-linear electrochemical fingerprint has obvious difference
also have obvious different characteristic parameters
sample cluster analysis divided into two categories. Conclusion: This method can be used to identify Codonopsis Radix and Gentianae Macrophylae Radix.
