摘要

刺荨麻标本于6月在图兹拉地区采集。以鲜叶和干叶为原料制备水提液，测定并比较其生物活性成分含量和抗氧化活性。提取方法有常规索氏法、超声辅助提取法和传统浸渍法。采用分光光度法对酚类和黄酮类进行了定量测定。采用铁还原抗氧化能力和DPPH自由基清除能力测定了荨麻水提物的抗氧化活性。索氏提取法提取的总酚和总黄酮含量最高，抗氧化能力最强，浸渍法提取的抗氧化能力最低。关键词:刺荨麻提取物;生物活性成分;提取

Effect of extraction technique on the content of bioactive components and antioxidant activity of aqueous extracts of fresh and dried nettle (Urtica dioica L.)

The samples of stinging nettle were collected during June in the Tuzla region. Aqueous extracts were prepared from fresh and dried leaves in order to determinate and compare content of bioactive components and antioxidant potential. Conventional soxhlet, ultrasound assisted extraction and traditional maceration extraction were used as extraction methods. Quantitative determination of phenols and flavonoids was carried out using spectrophotometric methods. Antioxidant activity of nettle aqueous extracts was determined using ferric reducing antioxidant power and DPPH free radical scavenging activity. Extracts obtained by Soxhlet extraction showed the highest total phenolic and flavonoid content and expected the highest antioxidant capacity, while extracts obtained by maceration gave the lowest results. KEYWORDS:stinging nettle extract;bioactive components;extraction;antioxidant
