L. and (L.) Hill represent medicinal plants used for the production of herbal teas and preparations with antioxidant and expectorant activity. Flowers and roots of both species possess the same biological activity. In the presented study, raw materials of wild growing and were compared in terms of the content and composition of phenolic compounds using a fast and simple HPLC-DAD method. The study showed that flowers of both species were rich in flavonoids. However, flowers were characterized with a distinctly higher content of isorhamnetin-3-O-glucoside, astragalin, and (+)-catechin, whereas occurred to be a richer source of rutoside and isorhamnetin-3-O-rutinoside. Hyperoside was found exclusively in flowers. Phenolic glycosides (primverin and primulaverin) were identified only in the roots. Their content was about ten times higher in in comparison with underground organs. The obtained results clearly show that both species differ distinctly in terms of the content and composition of phenolic compounds. The compounds differentiating both species to the highest degree (hyperoside, in flowers, as well as primverin and primulaverin, in the roots) may be useful chemical markers in the identification and evaluation of both species.
L. 和 (L.) Hill 代表用于生产具有抗氧化和祛痰活性的花草茶及制剂的药用植物。这两个物种的花和根具有相同的生物活性。在本研究中，使用快速简便的HPLC-DAD方法，对野生生长的 和 的原材料中酚类化合物的含量和组成进行了比较。研究表明，这两个物种的花都富含黄酮类化合物。然而， 花中异鼠李素-3-O-葡萄糖苷、黄芪苷和(+)-儿茶素的含量明显更高，而 则是芸香苷和异鼠李素-3-O-芸香糖苷更丰富的来源。金丝桃苷仅在 花中被发现。酚苷（樱草苷和报春花苷）仅在根中被鉴定出来。与 的地下器官相比，其含量在 中高出约十倍。所得结果清楚地表明，这两个 物种在酚类化合物的含量和组成方面存在明显差异。在区分这两个物种方面程度最高的化合物（花中的金丝桃苷以及根中的樱草苷和报春花苷）可能是鉴定和评估这两个物种的有用化学标志物。
