During the last decade, the popularity of hemp products has been rising rapidly. Products containing cannabidiol (CBD) are of predominant interest. Traditional hemp products are frequently enriched by CBD due to their potential therapeutic effects. Cannabidiol occurs naturally in hemp juice together with other biologically active substances, such as terpenes, flavonoids, and stilbenoids. These constituents act synergistically. This study aimed to observe the influence of the hemp plant developmental stage on its chemical composition and antioxidant activity. The hemp plants were analyzed during three vegetative stages, i.e., before, during, and after flowering. The collected samples were evaluated using the following analyses: total polyphenolic content and profile, terpenoid and cannabinoid contents, and ferric reducing antioxidant power. The results revealed statistically significant differences between the samples in almost all set parameters. The optimal period for hemp harvest depends on desirable compounds, i.e., phenolic content is the highest before flowering, while the levels of cannabinoids and terpenoids are the highest during the flowering period.
在过去十年中，大麻产品的受欢迎程度迅速上升。含大麻二酚（CBD）的产品备受关注。传统大麻产品因其潜在的治疗作用，常富含CBD。大麻二酚与其他生物活性物质（如萜类、黄酮类和芪类）一起天然存在于大麻汁中。这些成分协同作用。本研究旨在观察大麻植物发育阶段对其化学成分和抗氧化活性的影响。在三个营养阶段，即开花前、开花期间和开花后，对大麻植物进行了分析。使用以下分析方法对采集的样本进行评估：总多酚含量和谱图、萜类和大麻素含量以及铁还原抗氧化能力。结果显示，几乎所有设定参数的样本之间存在统计学上的显著差异。大麻收获的最佳时期取决于所需的化合物，即酚类含量在开花前最高，而大麻素和萜类的含量在开花期最高。
