The aim of this study is to evaluate the antioxidant properties of 70% methanolic extracts and the correlation between several antioxidant activities in selected Umbelliferae plants, based on total phenolic content (TPC) and total flavonoid content (TFC). For Umbelliferae plants extracts, the IC of DPPH radical (100 μM) quenching activities for extract, TPC, and TFC were 39∼179 μg dry weight (DW)/mL, 14.08∼38.11 μg TPC/mL, and 0.36∼1.51 μg TFC/mL, respectively. The oxygen radical absorbance capacity (ORAC) of extracts ranged from 11.44 to 42.88 mg Trolox equivalent (TE)/g DW extract, whereas ORAC for TPC and TFC was 47.40∼240.19 mg TE/g and 0.72∼11.22 g TE/g, respectively. The TPC had a superior linear correlation (r=0.817) with 2,2'-azinobis (3-ethylbenzothiazoline-6-sulfonic acid) values. Of the 14 Umbelliferae plant extracts, , , , , and showed the strongest antioxidant activity.
本研究旨在基于总酚含量（TPC）和总黄酮含量（TFC），评估70%甲醇提取物的抗氧化性能以及所选伞形科植物中几种抗氧化活性之间的相关性。对于伞形科植物提取物，提取物、TPC和TFC对DPPH自由基（100 μM）淬灭活性的IC分别为39∼179 μg干重（DW）/mL、14.08∼38.11 μg TPC/mL和0.36∼1.51 μg TFC/mL。提取物的氧自由基吸收能力（ORAC）范围为11.44至42.88 mg Trolox当量（TE）/g DW提取物，而TPC和TFC的ORAC分别为47.40∼240.19 mg TE/g和0.72∼11.22 g TE/g。TPC与2,2'-偶氮二（3-乙基苯并噻唑啉-6-磺酸）值具有较强的线性相关性（r = 0.817）。在14种伞形科植物提取物中， 、 、 、 和 表现出最强的抗氧化活性。
