Tartary buckwheat is a plant recognized for its resistance to various environmental stresses. Due to its valuable source of phenolic compounds, is also characterized as a medicinal plant; therefore, the aim of this study was to investigate the drought stress for the levels of phenolic compounds in the morphological parts of the plant.
This experiment was conducted in 7 L pots under laboratory conditions. Phenolic compounds were identified using a UHPLC-MS chromatography system. Antioxidant activity was assessed using well-known methods, including the DPPH scavenging activity and ferrous ion chelating activity.
In Tartary buckwheat leaves, stems, seeds, and husks, 57 phenolic compounds were identified, with a predominance of quercetin 3-rutinoside, quercetin, kaempferol-3-rutinoside, kaempferol, and derivatives of coumaric acid. It was observed that the Tartary buckwheat samples subjected to drought stress exhibited a slight decrease in the majority of individual phenolic compounds.
The measurement of biological parameters indicated that plant regeneration after drought stress demonstrated a rapid recovery, which can be a positive response to the progression of climate changes.
苦荞麦是一种以其对各种环境胁迫的抗性而闻名的植物。由于其富含酚类化合物，它也被视为一种药用植物；因此，本研究的目的是调查干旱胁迫对该植物形态部分中酚类化合物水平的影响。
本实验在实验室条件下的7升花盆中进行。使用超高效液相色谱-质谱（UHPLC-MS）色谱系统鉴定酚类化合物。采用包括DPPH清除活性和亚铁离子螯合活性等知名方法评估抗氧化活性。
在苦荞麦的叶、茎、种子和壳中，鉴定出57种酚类化合物，其中以槲皮素3-芸香糖苷、槲皮素、山奈酚-3-芸香糖苷、山奈酚和香豆酸衍生物为主。观察到遭受干旱胁迫的苦荞麦样品中，大多数单个酚类化合物略有减少。
生物学参数的测量表明，干旱胁迫后的植物再生表现出快速恢复，这可能是对气候变化进程的一种积极反应。
