Abstract

ABSTRACT Chili peppers are among the most important vegetables in the world. The demand of this fruit reveals a noticeable rapid increasing, which importance is mainly due to its nutraceutical composition. These fruits are rich in capsaicinoids, phenolic compounds, carotenoids, and others, including vitamins. In this study, a comparative evaluation between two extraction methods of bioactive compounds of fourteen chili pepper cultivars was performed. Two extraction methods for antioxidants, the time-solvent and the ultrasound were evaluated. The design of the experiment was completely randomized with three repetitions where variables evaluated were total phenolic compounds, flavonoids content, antioxidant capacity and capsaicin. Results showed that the phenolic compounds oscillated between 48.7 - 634.1 mg GAE/100 g dry weight (DW), the flavonoids content varied from 1 - 97 mg QE/100 g DW, the antioxidant activity from 65 - 348 µmol Trolox/g DW and the capsaicin content oscillated from 0.3 - 922 mg/100 g DW. The extraction method with higher values of bioactive compounds for each of the chili pepper types was the ultrasound for all the measured variables.

两种提取方法对辣椒和甜椒品种抗氧化性能的影响

摘要辣椒是世界上最重要的蔬菜之一。这种水果的需求呈现出明显的快速增长，其重要性主要是由于其营养成分。这些水果富含辣椒素、酚类化合物、类胡萝卜素和其他物质，包括维生素。本研究对14个辣椒品种的两种生物活性化合物提取方法进行了比较评价。对抗氧化剂的两种提取方法，时间溶剂法和超声波法进行了评价。实验设计完全随机，重复三次，评估的变量为总酚类化合物、黄酮类化合物含量、抗氧化能力和辣椒素。结果表明，酚类化合物在48.7-634.1 mg GAE/100 g干重（DW）之间波动，黄酮类化合物含量在1-97 mg QE/100 g DW之间变化，抗氧化活性在65-348µmol Trolox/g DW范围内变化，辣椒素含量在0.3-922 mg/100 g DW。每种辣椒类型的生物活性化合物值较高的提取方法是对所有测量变量进行超声波提取。
