Abstract

Two samples of tartary buckwheat (Fagopyrum tataricum Gaertn.) from China and one from Luxembourg were studied by high-performance liquid chromatography (HPLC) to reveal the possibilities of growing tartary buckwheat herb as a possible source of rutin, quercetin, and quercitrin. The content of rutin was determined as up to 3% dry weight (DW) in tartary buckwheat herb. Quercitrin values were in the range of 0.01-0.05% DW. Only traces of quercetin were detected in just some of the samples. Tartary buckwheat seeds contained more rutin (about 0.8-1.7% DW) than common buckwheat seeds (0.01% DW). Rutin and quercetin content in seeds depends on variety and growing conditions. Tartary buckwheat seeds contained traces of quercitrin and quercetin, which were not found in common buckwheat seeds.

摘要

采用高效液相色谱法（HPLC）对来自中国的两份苦荞（鞑靼荞麦）样本和一份来自卢森堡的苦荞样本进行了研究，以揭示种植苦荞草作为芦丁、槲皮素和槲皮苷可能来源的可能性。苦荞草中芦丁的含量测定为高达3%干重（DW）。槲皮苷含量在0.01 - 0.05% DW范围内。仅在部分样本中检测到痕量的槲皮素。苦荞种子所含芦丁（约0.8 - 1.7% DW）比普通荞麦种子（0.01% DW）更多。种子中芦丁和槲皮素的含量取决于品种和生长条件。苦荞种子含有痕量的槲皮苷和槲皮素，而普通荞麦种子中未发现这些成分。
