| titleOfInvention | Liquid/liquid interface electrochemical detection method for traditional Chinese medicine component emodin |
| abstract | The invention provides a liquid/liquid interface electrochemical detection method of traditional Chinese medicine component emodin, which is characterized in that a four-electrode electrolysis device is adopted, a polyvinylidene fluoride membrane is used for modifying a water/1, 6-dichlorohexane interface, and the content of the emodin in a sample is quantitatively detected by a differential pulse voltammetry method. The method is characterized in that a polyvinylidene fluoride membrane is used for modifying a water/1, 6-dichlorohexane interface, and a differential pulse voltammetry is adopted to draw a standard curve of peak current and emodin concentration generated when emodin is transferred on the water/1, 6-dichlorohexane interface. The traditional Chinese medicines of the root of giant knotweed, the rumex madaio (root, stem and leaf), the aloe plant and the aloe beverage are extracted and centrifugally separated for pretreatment, the differential pulse voltammetry is used for detecting emodin in the extract of the root of giant knotweed, the rumex madaio (root, stem and leaf) and the aloe leaf and the aloe beverage, and the emodin content in the sample is obtained according to the drawn standard curve. The invention provides a simple and rapid method for electrochemically detecting emodin. |
