生物活性化合物大部分是从天然来源获得的。从固体样品中测定植物化学物质通常需要几个连续的步骤，如果其中一个步骤没有正确执行，则分析的总体性能将很差，将引入错误，因此，结果可能不一致。样品制备用于提高分析的效率，消除或减少潜在的干扰，通过增加分析混合物中分析物的浓度来提高分析的灵敏度，有时还用于将感兴趣的分析物转化为更合适的形式
Bioactive compounds are largely obtained from natural sources. For the determination of phytochemicals from solid samples several consecutive steps are usually necessary, and if one of them is not properly followed, the overall performance of the analysis will be poor, errors will be introduced, and consequently, inconsistency in the results can be expected. Sample preparation is used to increase the efficiency of an analysis, to eliminate or reduce potential interferences, to enhance the sensitivity of the analysis by increasing the concentration of the analyte in the assay mixture, and sometimes to transform the analytes of interest into a more suitable form that can be easily
