| Abstract: | This article established the way to mensurate the content of niacinamide in metaldehyde by DAD-HPLC, and the mobile phase system and conditions. With methanol-water （15：85） as the mobile phase, DAD ultraviolt detector, the peak was detected at 261 nm. The results of the sample for the separation and determination with liquid chromatography indicated that this method was simple and quick, the nature finally reappeared well, the quota was accurate. Its accuracy has a significantly linear relation with its precision. |
