Abstract

Antioxidant plays an important role in the body's defense against various diseases, because antioxidant compounds were able to prevent the bad effects caused by free radicals. Phenolic compounds and flavonoids are known as natural antioxidant o from plants. Jalantir (Coryza sumatrensis) is known contain phenolic and flavonoid. The aim of this study was to determine total phenolic content, flavonoid content and antioxidant activity using the 2,2-diphenyl-1-picrylhydrazyl (DPPH) method. The results showed that jalantir extract had a total phenolic content of 38.27 mg GAE/g and flavonoid content of 56.60 mg QE/g. Meanwhile, for the antioxidant activity, value of IC50 for extract, water fraction, ethyl acetate, and n-hexane were 9.76; 45.91; 60.75; and 74.31 ppm respectively. Jalantir extract was the strongest antioxidant category compared to other fractions.Keywords: phenolics, flavonoids, antioxidant, jalantir

茉莉叶（Coryza sumatrensis）的总酚含量、芳香物质和抗氧化活性

抗氧化剂在人体抵御各种疾病的过程中发挥着重要作用，因为抗氧化剂化合物能够防止自由基造成的不良影响。众所周知，酚类化合物和类黄酮是植物中的天然抗氧化剂。众所周知，Jalantir（Coryza sumatrensis）含有酚类和类黄酮。本研究的目的是采用 2,2-二苯基-1-苦基肼（DPPH）法测定总酚含量、类黄酮含量和抗氧化活性。结果表明，贾兰蒂提取物的总酚含量为 38.27 毫克 GAE/克，类黄酮含量为 56.60 毫克 QE/克。同时，在抗氧化活性方面，提取物、水馏分、乙酸乙酯和正己烷的 IC50 值分别为 9.76、45.91、60.75 和 74.31 ppm。与其他馏分相比，珈蓝提尔提取物的抗氧化性最强。关键词：酚类化合物、黄酮类化合物、抗氧化剂、珈蓝提尔
