L. has a long tradition of use in folk medicine. The chemical composition of the roots and green parts of the plant is quite well known. There is the lowest amount of data on the cypsela (fruit) of this plant. In this study, the microscopic structures and the chemical composition of the cypsela were investigated. Preliminary cytochemical studies of the structure of the L. cypsela showed the presence of substantial amounts of protein and lipophilic substances. The chemical composition of the cypsela was investigated using spectrophotometry, gas chromatography with mass spectrometry, and high-performance liquid chromatography with spectrophotometric and fluorescence detection. The cypsela has been shown to be a rich source of macro- and microelements, vegetable oil (25%), α-tocopherol (approx. 2 g/kg of oil), protein (approx. 36% seed weight), and chlorogenic acids (approx. 22 g/kg seed weight). It also contains a complex set of volatile compounds. The cypsela is, therefore, a valuable source of nutrients and bioactive substances.
L. 在民间医学中有着悠久的使用传统。该植物的根和绿色部分的化学成分已相当清楚。关于该植物的瘦果（果实）的数据最少。在这项研究中，对瘦果的微观结构和化学成分进行了研究。对 L. 瘦果结构的初步细胞化学研究表明，存在大量的蛋白质和脂溶性物质。使用分光光度法、气相色谱-质谱联用和高效液相色谱-分光光度法和荧光检测法研究了瘦果的化学成分。结果表明，瘦果是大量宏量和微量元素、植物油（25%）、α-生育酚（约 2g/kg 油）、蛋白质（约 36%种子重量）和绿原酸（约 22g/kg 种子重量）的丰富来源。它还含有一套复杂的挥发性化合物。因此，瘦果是营养物质和生物活性物质的宝贵来源。
