ABSTRACT

In this study, the banana flower was divided into bract and male flowers and extracted with water and ethanol, at different temperatures, and then the functionality of the obtained extract was evaluated and the bioactive compounds were analyzed. The findings showed that the banana flower with an ethanol extract of 50% and a temperature of 50°C (FE-50%-50°C) had the best DPPH radical scavenging ability and hydroxyl radical scavenging ability of 97.44% and 38.86%, respectively. Moreover, the FE-50%-50°Calso had the best reducing power. In terms of its ferrous ion chelating ability, the banana flower ethanol 50% extract at room temperature (FE-50%-RT) had the best ferrous ion chelating ability of 96.82%. The 95% ethanol extract of the banana flower was effective in inhibiting α-amylase, α-glucosidase, and lipase activity was 31.75%, 84.17%, and 70.59%, respectively. FE-50%-50°C had the highest alcohol dehydrogenase activity of 74.92%. In addition, the FE-95%-50°C had the highest content of lupeol and umbelliferone, which were 40.10 and 90.83 μg/mg, respectively.

摘要

本研究将香蕉花分为片花和雄花，并在不同温度下用水和乙醇提取，然后评估所得提取物的功能并分析其生物活性成分。结果表明，乙醇提取率为50％，温度为50°C（FE-50％-50°C）的香蕉花具有最佳的DPPH自由基清除能力和羟自由基清除能力，分别为97.44％和38.86％，分别。此外，FE-50％-50°C的还原力也最好。就其亚铁离子螯合能力而言，室温下50％香蕉花乙醇提取物（FE-50％-RT）的最佳亚铁离子螯合能力为96.82％。香蕉花的95％乙醇提取物可有效抑制α-淀粉酶，α-葡萄糖苷酶，脂肪酶活性分别为31.75％，84.17％和70。分别为59％。FE-50％-50°C具有最高的酒精脱氢酶活性，为74.92％。此外，FE-95％-50°C的羽扇豆酚和伞形酮含量最高，分别为40.10和90.83μg/ mg。
