Plant phenolics and flavonoids have a powerful biological activity, which outlines the necessity of their determination. The phenolics and flavonoids content of 20 medicinal plants were determined in the present investigation. The phenolic content was determined by using Folin-Ciocalteu assay. The total flavonoids were measured spectrophotometrically by using the aluminium chloride colorimetric assay. The results showed that the family Mimosaceae is the richest source of phenolics, (Acacia nilotica: 80.63 mg gallic acid equivalents, Acacia catechu 78.12 mg gallic acid equivalents, Albizia lebbeck 66.23 mg gallic acid equivalents). The highest total flavonoid content was revealed in Senna tora which belongs to the family Caesalpiniaceae. The present study also shows the ratio of flavonoids to the phenolics in each sample for their specificity.
植物酚类和黄酮类化合物具有强大的生物活性，这凸显了对其进行测定的必要性。本研究测定了20种药用植物中的酚类和黄酮类化合物含量。酚类含量采用福林-西奥尔特法测定。总黄酮采用氯化铝比色法进行分光光度测定。结果表明，含羞草科是酚类物质最丰富的来源（阿拉伯胶树：80.63毫克没食子酸当量，儿茶相思树78.12毫克没食子酸当量，合欢66.23毫克没食子酸当量）。属于苏木科的决明子总黄酮含量最高。本研究还展示了每个样品中黄酮类与酚类的比例以体现其特异性。
