1前言GA4+76-BA是赤霉素和细胞分裂素的复配产物,在农业中应用广泛。在葡萄上可以用于发芽后促进发芽整齐,减轻冻害,花后主要用于防落保果、果实膨大等。我公司研发部对此进行了产品开发。目前赤霉酸A4+A7具体的分析方法未见报道。本文采用高效液相色谱法,对该产品进行分析,该方法操作简便、快速、准确,分离效果好,准确度和精密度均能达到定量分析的要求,可以作为企业生产过程质量控制的参考方法。
1 Introduction GA4 + 76-BA is a complex product of gibberellin and cytokinin, widely used in agriculture. The grapes can be used after germination to promote germination, reduce frost damage, after anthesis is mainly used for anti-drop fruit, fruit enlargement. R & D department of our company carried out product development. The current Gibberellic acid A4 + A7 specific analysis methods have not been reported. In this paper, the product is analyzed by high performance liquid chromatography. The method is simple, rapid and accurate, and the separation effect is good. The accuracy and precision can reach the requirements of quantitative analysis, which can be used as the reference method of quality control in the production process .
