Antioxidant capacity of the aqueous extract of Malva sylvestris was measured by its ability to scavenge the DPPH and superoxide anion radicals and to induce the formation of a phosphomolybdenum complex. Analysis of the extract, carried out by different chromatographic techniques, led to the isolation of eleven compounds: 4-hydroxybenzoic acid, 4-methoxybenzoic acid, 4-hydroxy-3-methoxybenzoic acid, 4-hydroxycinnamic acid, ferulic acid, methyl 2-hydroxydihydrocinnamate, scopoletin, N-trans-feruloyl tyramine, a sesquiterpene, (3R,7E)-3-hydroxy-5,7-megastigmadien-9-one, and (10E,15Z)-9,12,13-trihydroxyoctadeca-10,15-dienoic acid. The antioxidant activities of all these compounds are reported.
通过锦葵水提取物清除二苯基苦味酰基自由基(DPPH)和超氧阴离子自由基以及诱导磷钼络合物形成的能力来测定其抗氧化能力。采用不同的色谱技术对提取物进行分析,分离出了11种化合物:4-羟基苯甲酸、4-甲氧基苯甲酸、4-羟基-3-甲氧基苯甲酸、4-羟基肉桂酸、阿魏酸、2-羟基二氢肉桂酸甲酯、东莨菪素、N-反式阿魏酰酪胺、一种倍半萜、(3R,7E)-3-羟基-5,7-大柱香波龙二烯-9-酮以及(10E,15Z)-9,12,13-三羟基十八碳-10,15-二烯酸。报告了所有这些化合物的抗氧化活性。
