This document specifies a rapid colloidal gold immunochromatographic detection method for bufenozide residues in vegetables and fruits. This document is suitable for the rapid detection of bufenozide residues in vegetables and fruits. Note 1: Vegetables include onions, cabbage, cauliflower, broccoli, kale, sprouts, leafy vegetables, stem lettuce leaves, Chinese cabbage, tomatoes, peppers, bell peppers, okra, stem lettuce, radish, Carrots, turnips. Note 2: Fruits include citrus fruits, pome fruits, apples, peaches, nectarines, blueberries, lingonberries, currants, grapes, kiwis, avocados, papayas, and melons. This method adopts the principle of competitive inhibition immunochromatography. The bufenozide in the sample is extracted and binds to the colloidal gold-labeled specific antibody, inhibiting the binding of the antibody to the antigen on the test line (T line) in the test strip, resulting in a change in the color of the test line (T line). . By comparing the color depth of the test line (T line) and the quality control line (C line), a qualitative analysis of bufenozide in the sample was performed.
