ABSTRACT

The objective of this paper was to examine the total polyphenols, vitamin C and capsaicin contents of pepper (varieties: Garam F1, Alma, Poseidon, Promontor, Slovakia, Claudius, Bhut Jolokia, Serrano, and Candlelight) and their correlation with the antioxidant activity by using the high performance liquid chromatography and Folin-Ciocalteu method. The limit of detection for capsaicin was 0.09 µg.g⁻¹.Vitamin C and capsaicin ranged from 95.76 to 2,139 and from 44.40 to 2,224 μg.g⁻¹ dry matter (DM), respectively. The determined total polyphenol content (TPC) ranged from 4,230 to 9,939 mg GAE.kg⁻¹ DM and the values of antioxidant activity (AA) determined by using DPPH •, FRAP and ABTS • + methods were in range 19.48–91.81, 19.08–61.46 and 15.72–65.70 μmol TE.g⁻¹ DM, respectively. Based on the statistical evaluation, there was a high correlation between vitamin C content and antioxidant activity of peppers. The obtained results suggest that due to the composition of bioactive compounds, especially antioxidants, the consumption of pepper fruits is an ideal choice for the prevention of the cell damage.

摘要

本文的目的是检查辣椒（品种：Garam F1、Alma、Poseidon、Promontor、Slovakia、Claudius、Bhut Jolokia、Serrano 和 Candlelight）的总多酚、维生素 C 和辣椒素含量及其与抗氧化活性的相关性采用高效液相色谱法和 Folin-Ciocalteu 方法。辣椒素的检测限为 0.09 µg.g ^{-1 .}维生素 C 和辣椒素的范围分别为 95.76 至 2,139 和 44.40 至 2,224 µg.g ^-1干物质 (DM)。测定的总多酚含量 (TPC) 范围为 4,230 至 9,939 mg GAE.kg ^-1 DM，使用 DPPH •、FRAP 和 ABTS • + 方法测定的抗氧化活性 (AA) 值范围为 19.48-91.81、19.08- 61.46 和 15.72–65.70 μmol TE.g^-1 DM，分别。根据统计评估，维生素C含量与辣椒的抗氧化活性之间存在高度相关性。所得结果表明，由于含有生物活性化合物，尤其是抗氧化剂，食用辣椒果实是预防细胞损伤的理想选择。
