The interest in L. has been on the rise recently, driven by its potential applications in various sectors, including the food industry, the medical sector, and other key areas. This crop possesses a diverse profile of essential fatty acids and a range of bioactive compounds, which exhibit properties that are highly significant for functional food ingredients and nutraceutical purposes. The objective of this study was to investigate the characteristic lipid and bioactive profiles of different plant parts (e.g., inflorescences and leaves) to ascertain their possible uses in nutritional and therapeutic fields. The fat content of the plant material was determined by the Soxhlet method, and gas chromatography was employed for the assessment of the fatty acids and selected bioactive compounds profile. In addition, some lipid quality indices were calculated with the purpose of providing a more in-depth discussion of these aspects beyond the traditional n-6/n-3 ratio. A distinct lipid composition was evident among the various plant parts. Compared to inflorescence samples, leaves typically contain higher proportions of SFAs, MUFAs, PUFAs, and n-3 fatty acids, along with a more favorable n-6/n-3 ratio, which may significantly impact nutritional value. Phytol-rich leaves can suggest its potential application as a functional feed or even a nutraceutical. Furthermore, the occurrence of hexacosane and related antimicrobial and antifungal compounds serves to enhance the practical utility of the leaves. Notably, hemp leaves are not merely a by-product, but rather offer significant practical applications.
近年来，由于L.在食品工业、医疗部门和其他关键领域等各个行业的潜在应用，人们对它的兴趣一直在上升。这种作物含有多种必需脂肪酸和一系列生物活性化合物，这些化合物对功能性食品成分和营养保健品具有非常重要的特性。本研究的目的是调查不同植物部位（如花序和叶子）的特征性脂质和生物活性成分，以确定它们在营养和治疗领域的可能用途。通过索氏提取法测定植物材料的脂肪含量，并采用气相色谱法评估脂肪酸和选定的生物活性化合物成分。此外，还计算了一些脂质质量指标，目的是在传统的n-6/n-3比值之外，对这些方面进行更深入的讨论。不同植物部位的脂质组成明显不同。与花序样品相比，叶子通常含有更高比例的饱和脂肪酸（SFAs）、单不饱和脂肪酸（MUFAs）、多不饱和脂肪酸（PUFAs）和n-3脂肪酸，以及更有利的n-6/n-3比值，这可能会显著影响营养价值。富含叶绿醇的叶子表明其作为功能性饲料甚至营养保健品的潜在应用价值。此外，二十六烷及相关抗菌和抗真菌化合物的存在增强了叶子的实际用途。值得注意的是，麻叶不仅仅是一种副产品，而是具有重要的实际应用价值。
