Abstract

The invention discloses an analysis method for the contents of active components in a benthiavalicarb isopropyl.dimethomorph compound preparation. The analysis method comprises the following steps of: utilizing a silica gel column with the column length of 250 mm and the column diameter of 4.6 mm, and taking methanol-water solution with the volume fraction of 35-55% as a mobile phase, wherein the flow velocity is 0.8-1.2 mL / min, and the column temperature is 10-50 DEG C; carrying out quantitative analysis on benthiavalicarb isopropyl and dimethomorph which are active components in the compound preparation by utilizing an ultraviolet detector or a diode array detector and a high performance liquid chromatography (HPLC) method, wherein the detection wavelength is 240-260 nm. The method has the advantages that the precision is high, the reproducibility is good, the accuracy is high and the repetitiveness is good; a basis is provided for the quantitative analysis of the active components in the benthiavalicarb isopropyl.dimethomorph compound preparation; the method has an important practical value for the application of the benthiavalicarb isopropyl.dimethomorph compound preparation in agricultural production practice.
