摘要

摘要本研究比较了传统提取方法(溶剂提取)和新型提取方法(超声辅助)对银椴花和苞片中酚类化合物的提取效果。对乙醇(70%)提取物的抗氧化活性进行了分析。采用Folin-Ciocalteu法测定总酚含量，采用DPPH自由基清除和铁还原抗氧化能力(FRAP)测定抗氧化能力。为了确定超声处理对提取的影响，两种方法均采用相同的提取参数。结果表明，超声辅助提取得到的提取物具有较高的总酚含量和抗氧化活性。

The influence of extraction method on antioxidant potential of Tilia argentea flowers and bracts

Abstract The objective of this work was to compare the extraction of phenolic compounds from Tilia argentea flowers and bracts by using conventional (solvent extraction) and novel (ultrasound assisted) extraction methods. Ethanol (70 %) extracts were analyzed for their antioxidant activities. Total phenolic content was determined using Folin-Ciocalteu method and the antioxidant potential was determined by DPPH radical scavenging and Ferric Reducing Antioxidant Power (FRAP) assays. To determine the effect of ultrasound treatment on the extraction, same extraction parameters were applied in both methods. The results showed that extracts obtained by ultrasound assisted extraction have higher total phenolic content and antioxidant activity.
