Abstract

In this work, an electrochemical oscillation system has been developed using the Belousov–Zhabotinsky reaction. The effect of the combination of each reagent, reaction temperature, and stirring speed on the induction period, oscillating period, and oscillating life were optimized. The nuts of Prunus persica, Prunus davidiana, and Prunus armeniaca have been widely used for medical purposes. The proposed electrochemical oscillation system was then used for the identification of P. persica, P. davidiana, and P. armeniaca. Three nuts exhibited very different electrochemical oscillation profiles. The dendrogram was divided into three main principal infrageneric clades. Each cluster only contains one species, suggesting that no outlier was observed in this study. Based on the discussed results, we proposed a simple method for herbal medicine identification.

Highlights

  • The fingerprint of traditional herbal medicine refers to the map of common peaks that can mark the characteristics of the traditional herbal medicine after proper pretreatment with a certain analysis method (Xie et al, 2006; Zhu et al, 2016; Wang et al, 2017)

  • Electrochemical Oscillation for Plant Indentification (Cui et al, 2019), and DNA fingerprint (Pawar et al, 2017; Selvakumari et al, 2017). These methods can be used for in-depth research on traditional herbal medicine, but proper pretreatment of traditional herbal medicine is required

Summary

Introduction

The fingerprint of traditional herbal medicine refers to the map of common peaks that can mark the characteristics of the traditional herbal medicine after proper pretreatment with a certain analysis method (Xie et al, 2006; Zhu et al, 2016; Wang et al, 2017). Electrochemical Oscillation for Plant Indentification (Cui et al, 2019), and DNA fingerprint (Pawar et al, 2017; Selvakumari et al, 2017) These methods can be used for in-depth research on traditional herbal medicine, but proper pretreatment of traditional herbal medicine is required. Due to the good reproducibility of the oscillating response, its application research is becoming more and more extensive, which provides a new idea and method for solving this problem
