Stinging nettle (SN) is an extraordinary plant from the botanical family. It is well-known and widely used in food and folk medicine to treat different disorders and diseases. This article aimed to study the chemical composition of SN leaves extracts, i.e., polyphenolic compounds and vitamins B and C, because many studies ascribed high biological potency to these compounds and their significance in the human diet. Besides the chemical profile, the thermal properties of the extracts were studied. The results confirmed presence of many polyphenolic compounds and vitamins B and C. It also showed that the chemical profile closely correlated with the applied extraction technique. The thermal analysis showed that analyzed samples were thermally stable up to about 160 °C. Thermal degradation of samples UAE, MAE, and MAC took place in four steps, and sample SE in three steps. Altogether, results confirmed the presence of health-beneficial compounds in stinging nettle leaves and indicated the possible application of its extract in pharmaceutical and food industries as both a medicinal and food additive.
荨麻（SN）是一种来自植物科的非凡植物。它在食品和民间医学中广为人知并被广泛用于治疗各种疾病和病症。本文旨在研究 SN 叶提取物的化学成分，即多酚化合物、维生素 B 和 C，因为许多研究认为这些化合物具有很高的生物效力，并且它们在人类饮食中的意义重大。除了化学特征外，还研究了提取物的热性能。结果证实了许多多酚化合物和维生素 B 和 C 的存在。它还表明，化学特征与所应用的提取技术密切相关。热分析表明，分析样品在约 160°C 以下是热稳定的。UAE、MAE 和 MAC 样品的热降解分四个步骤进行，SE 样品分三个步骤进行。总的来说，结果证实了荨麻叶中存在有益健康的化合物，并表明其提取物可能作为药用和食品添加剂应用于制药和食品工业。
