摘要

印度尼西亚盛产苏昆（Artocarpus altilis (Parkinson) Fosberg）。然而，其使用量却非常有限。本研究旨在分析印尼未充分利用的植物之一苏昆叶的抗氧化活性。成熟的苏昆叶采用浸渍法提取，溶剂为 96% 的工业乙醇。采用 Burdan 和 Olezek 方法（2001 年）进行 DPPH 分析。采用 IC50 法分析苏昆叶的维生素 C 含量。分析的浓度分别为 2、3、4、5 和 6 ppm。通过 DPPH 法，发现提取物的总抗氧化活性分别为 45.79、48.11、49.38、50.95 和 51.70。IC 50 分析表明，每种浓度的提取物中维生素 C 的含量分别为 54.82、57.72、60.64、63.94 和 65.49。由此可以得出结论，苏昆叶具有很强的抗氧化活性。关键词：抗氧化分析、苏昆（海芋）、营养分析、未充分利用的植物

Antioxidant Analysis of Sukun (Artocarpus Altilis (Parkinson) Fosberg) Leaves Using DPPH and IC50 Methods

Sukun (Artocarpus altilis (Parkinson) Fosberg) are abundantly found in Indonesia. However, the usage of it was very limited. This research was conducted to analyze the antioxidant activity of Sukun leaves as one of the underused plants in Indonesia. Mature Sukun leaves were extracted using maceration method where 96% technical ethanol was used as the solvent. DPPH analysis was conducted using Burdan and Olezek method (2001). IC50 method was performed to analyze Vit C content of Sukun leaves. The analysis was performed on 2, 3, 4, 5, and 6 ppm concentrations. By using the DPPH method, it was found that the total antioxidant activity of the extract was 45.79; 48.11; 49.38; 50.95; and 51.70 respectively. IC 50 analysis shows that the vitamin C content of the extract was 54.82; 57.72; 60.64; 63.94; and 65.49 respectively for every concentration. It can be concluded that Sukun leaves showed strong antioxidant activity. Keywords: antioxidant analysis, Sukun (Artocarpus altilis), nutrition analysis, underused plant
