Abstract

AbstractExtraction of ripened noni juice has been carried out using ethanol and water. The purpose of this study was to determine the total phenolic, total flavonoids, scopoletin, content and antioxidant activity of the ripened noni juice extract. The activity test was carried out on the ripened noni juice extract without and with the addition of ethanol and water solvent. The phytochemical assays of ethanol extract of the ripened noni juice showed that thetotal phenolic content was 3,94 mg gallic acid equivalent/g extract, the total flavonoids was 0,59 mg quercetin equivalent /g extract, the IC50 antioxidant activity was 24,92 mg/L, scopoletin content was 2,45 mg/gram.Keywords : Antioxidant, flavonoids, phenolic, ripened noni juice, scopoletin
诺丽汁成熟提取物总酚、总黄酮、东莨菪碱含量及抗氧化活性研究
摘要采用乙醇和水对成熟诺丽汁进行提取。本研究旨在测定成熟诺丽汁提取物的总酚、总黄酮、东莨菪碱含量及抗氧化活性。对成熟诺丽汁提取物进行了不加乙醇和添加水溶剂的活性试验。对成熟诺丽汁乙醇提取物进行植物化学分析,其总酚含量为3.94 mg没食子酸当量/g提取物,总黄酮含量为0.59 mg槲皮素当量/g提取物,IC50抗氧化活性为24.92 mg/L,东莨菪碱含量为2.45 mg/g提取物。关键词:抗氧化剂,黄酮类化合物,酚类物质,成熟诺丽汁,东莨菪碱
