In the present study we demonstrate the identification of phenolic compounds and the phenolic contents of the methanol extracts from stem and buds of Calligonum polygonoides with antioxidant activity. Eleven and nine phenolic compounds were identified and quantified from stem and buds, respectively by high-performance liquid chromatography (HPLC). p-Coumaric acid was predominant in stem and gallic acid in buds. In general, the samples with the highest phenolic contents had the highest antioxidant activities. Stem and buds sparked attention due to their high phenolic contents and antioxidant activities. The Results from present study reveal that the C. polygonoides could be considered as a promising source of antioxidant phytochemicals.

在本研究中,我们证明了酚类化合物的鉴定以及具有抗氧化活性的caligonum polygonoides茎和芽中甲醇提取物的酚类含量。通过高效液相色谱 (HPLC) 分别从茎和芽中鉴定出11种和9种酚类化合物并对其进行定量。对香豆酸在茎中占主导地位,在芽中占主导地位。通常,酚类含量最高的样品具有最高的抗氧化活性。茎和芽由于其高酚类含量和抗氧化活性而引起了人们的关注。本研究的结果表明,多角藻可被认为是抗氧化剂植物化学物质的有希望的来源。
