Arum dioscoridis, locally called 'Gavur pancari', is a wild plant the leaves of which have been used as vegetable and for preparing special soup which has a sour taste. This study was set up to determine in vitro antioxidant activities and total phenolic and flavonoid contents of different extracts of A. dioscoridis. Free radical scavenging activity was evaluated using 2,2-diphenyl-1-picrylhydrazyl (DPPH) and ferric reducing activity with different concentrations of ethanol, methanol, acetone and water extracts of the plant leaves. Total phenolic and flavonoid contents were widely variable depending on solvents. Ethanol and methanol extractions of the plant material showed better performances with respect to both phenolic and flavonoid contents, respectively. The highest phenolic and flavonoid contents of ethanol and methanol extracts were 100.890 mg/g GAE and 72.643 mg/g QE, respectively. The lower DPPH scavenging and ferric reducing activities were determined in comparison with previous reports and standard synthetic chemicals.
紫萁，俗称“野葛菜”，是一种野生植物，其叶子可作为蔬菜，并用于制作具有酸味的特殊汤。本研究旨在测定不同提取物的体外抗氧化活性以及总酚和类黄酮含量。通过使用 2,2-二苯基-1-苦基肼（DPPH）和不同浓度的乙醇、甲醇、丙酮和水提取物来评估自由基清除活性。总酚和类黄酮含量因溶剂而异。与其他溶剂相比，植物材料的乙醇和甲醇提取物在酚类和类黄酮含量方面表现更好。乙醇和甲醇提取物的最高总酚和类黄酮含量分别为 100.890 mg/g GAE 和 72.643 mg/g QE。与之前的报道和标准合成化学品相比，DPPH 清除和铁还原活性较低。
